"That murder of Sir Charles Moon." Halliday quivered with surprise. It was so amazing that Laurance should hit upon the very subject, which employed his own thoughts. "Yes?" he inquired. "You are engaged to Miss Moon; you were in the house when the crime was committed; you saw the body; you-"
"Stop! Stop! I was not in the house when the crime was committed. I returned there from the theatre some time later-in fact about midnight. I certainly did see the body. As to being engaged to Miss Moon-h'm! I came to see about that, Freddy."
"The deuce you did. Great minds jump. What?" Laurance puffed a blue cloud, sat down astride a chair and leaned his arms on the back. "Strange!"
"That you and I should be on the hunt. Well it is."
"On the hunt!" echoed Laurance, staring. "What do you mean?"
"I should rather ask that question of you," said Dan drily. "Sir Charles is dead and buried these many weeks, and the woman who assassinated him can't be found, in spite of the reward and the effort of the police. Why, at this late hour, do you wish to rake up stale news? I thought that The Moment was more up-to-date."
"It will be very much up-to-date when the next murder is committed," observed Laurance, grimly and significantly. The legs of Dan's chair grated, as he pushed back in sheer surprise. "What do you mean by the next murder?" he demanded sharply. "Well, this gang-"
"Gang! gang! Who says there is a gang?" and Dan's thoughts flew back to Durwin's reason for visiting Sir Charles. "Humph!" growled Laurance, thrusting his hands into his pockets. "I'm disappointed. I thought you knew more."
"I know a good deal," retorted the other quickly, "but I don't intend to talk to you about what I know until I learn your game."
"What about your own?" "That comes later also," said Halliday promptly. "Go on! I want to know why you rake up Moon's murder."
"Naturally you do, seeing you are engaged to the daughter."
"Am I? I am not quite sure. She loves me and I love her, but the new baronet wants her to marry Lord Curberry. She refused, and I kicked up a row some hours back. Result, we are on probation for one year, during which time I am to discover the assassin of Sir Charles."
"And if you don't?"
"Time enough to talk about that when I fail," said Halliday coolly; "at least I have twelve months to hunt round. I came for your help, but it seems that you want mine. Why?" Freddy, through sheer absence of mind, flung away a half-smoked cigarette and lighted another. Then he rose and strolled across the room to lean his shoulders against the mantelpiece. "We can help one another, I think," was his final observation. "I hope so. In any case I intend to marry Lillian. All the same, to pacify Sir John, I am willing to become a detective. You know my game. Yours?"
"Listen," said Laurance vivaciously. "I forgot all about the murder, since there seemed to be no chance of the truth coming to the light, and so did every one else for the same reason. But a few nights ago I was dining out, and met a chap called Durwin-"
"Scotland Yard man," interrupted Dan, nodding several times. "He came to see Sir Charles on business and found the corpse." "Just so. Well, after dinner we had a chat, and he told me that he was anxious to learn who killed Moon, because he didn't want any more murders of the kind to happen-as a police official, you understand."
"Strange he should be confidential on that point," murmured Halliday thoughtfully, "seeing that he wished his theory regarding a possible gang kept quiet, in the hope of making discoveries."
"He has changed his mind about secrecy, and so has Tenson," said Freddy. "Oh!" Dan raised his eyebrows. "The Inspector. You have seen him also?" Laurance nodded. "After I saw Durwin, and learned what he had to say I saw Tenson, and interviewed him. They told me about the fly on the neck, and remembering the case of the purple fern, and having regard to the fact that the fly in question was artificial, both men are inclined to believe in the existence of a gang, whose trade-mark the said fly is." Dan nodded again. "Quite so; and then Durwin came to see Moon and hear about the gang. He found him dead."
"So you said; so Durwin said," rejoined Laurance quietly. "It seems very certain, putting this and that together, that Sir Charles became dangerous to this gang, whatever it is, and wherever it exists, so was put to death by the false Mrs. Brown, who came expressly to kill him."
"So far I am with you on all fours," said Halliday. "Well?"
"Well, both Durwin and Tenson, dreading lest the gang may commit another crime, wish me to make the matter as public as I can, so as to frighten the beasts."
"H'm!" said Dan, looking at his neat brown boots. "They have changed their minds, it seems. Their first idea was to keep the matter quiet, so as to catch these devils red-handed. However, publicity may be a good thing. How do you intend to begin?"
"I have got facts from Tenson and from Durwin," said Freddy promptly; "and now, since you saw the body and found the fly, I want to get the facts from you. On what I acquire I shall write a letter in that extra sheet of ours, and you can be pretty certain from what you know of human nature that any amount of people will reply to my letter."
"They may reply to no purpose."
"I'm not so sure of that, Dan. If I mention the fly as a trade-mark and recall the strange case of the purple fern, some one may write about matters known to themselves from positive knowledge. If this gang exists, it has committed more murders than one, but the fly being a small insect may not have been noticed as a trade-mark in the other crimes. I wonder you spotted it anyhow."
"It was easily seen, being on the back of the neck near the wound. Besides, flies in November-the month of the murder-are rare. Finally Tenson discovered the fly to be artificial, which shows that it was purposely placed on the dead man's neck, near the wound. H'm!" he reflected, "perhaps someone may know of some crime with the fly trade-mark, and in that case we can be certain that such a gang does exist."
"So I think," cried Laurance quickly, "and for that reason I intend to start a discussion by writing an open letter. Publicity may frighten the beasts into dropping their trade; on the other hand, it may goad the gang into asserting itself. In either case the subject will be ventilated, and we may learn more or less of the truth."
"Yes. I think it's a good idea, Freddy. And the perfume? Did Durwin or the Inspector tell you anything about the perfume. No, I can see by your blank stare that they didn't. Listen, Freddy, and store this knowledge in your blessed brain, my son. It is a clue, I am sure," and Halliday forthwith related to his attentive listener details concerning the strange perfume which had impregnated the clothes of the dead man. "And Sir Charles hated perfumes," he ended, emphatically; "he didn't even like Lillian or Mrs. Bolstreath to use them, and they obeyed him." "Curious," mused the journalist, and idly scribbling on his blotting-paper; he was back at his desk by this time. "What sort of scent is it?"
"My dear chap, you ask me to describe the impossible," retorted Dan, with uplifted eyebrows. "How the deuce can I get the kind of smell into your head? It must be smelt to be understood. All I can say is that the perfume was rich and heavy, suggestive of drowsiness. Indeed, I used that word, and Tenson thought of some kind of chloroform used, perhaps, to stupefy the victim before killing him. But there was an odor about the mouth or nose."
"On the handkerchief, perhaps?" suggested the reporter. "No. Tenson smelt the handkerchief."
"Well, if this Mrs. Brown used this perfume, you and Miss Moon and Mrs. Bolstreath must have smelt it on her in the hall. I understand from Durwin that you all three saw the woman." "Yes. And Lillian, poor girl, persuaded her father to see the wretch. But we did not smell the perfume on the woman. Tenson or Durwin-I forget which-asked us the question."
"Humph!" said Laurance, after a pause; "it may be a kind of trade-mark, like the fly business." He took a note. "I shall use this evidence in my letter to the public. I suppose, Dan, you would recognize the scent again?"
"Oh, yes! I have a keen sense of smell, you know. But I don't expect I shall ever drop across this particular fragrance, Freddy."
"There's always Monsieur Chance, you know," remarked Laurance, tapping his white teeth with a pencil. "Perhaps the gang use this scent so as to identify one another-in the dark it may be-like cats. How does that strike you?"
"As purely theoretical," said Dan, with a shrug, and reached for another cigarette; "it's a case of perhaps, and perhaps not." Laurance assented. "But everything so far is theoretical in this case," he argued; "you have told me all you know?"
"Every bit, even to my year of probation. Do you know Curberry?"
"Yes. He was a slap-up barrister. A pity he got title and money, as he has left the Bar, and is a good man spoiled. Lucky chap all the same, as his uncle and cousin both died unexpectedly, to give him his chance of the House of Lords."
"How did they die?" "Motor accident. Car went over a cliff. Only the chauffeur was saved, and he broke both legs. Do you know the present Lord Curberry?"
"I have seen him, and think he's a dried-up, cruel-looking beast," said Dan, with considerable frankness. "I'd rather see Lillian dead than his wife."
"Hear, hear!" applauded Laurance, smiling. "The girl's too delightful to be wasted on Curberry. You have my blessing on the match, Dan."
"Thanks," said Halliday ruefully, "but I have to bring it off first. Sir John's infernally clever, and managed to get both Lillian and me to consent to let matters stand over for a year, during which time I guess he'll push Curberry's suit. But I can trust Lillian to be true to me, bless her, and Mrs. Bolstreath is quite on our side. After all," murmured the young man disconsolately, "it's only fair that Sir Charles should be avenged. Perhaps it would be selfish for Lillian and me to marry and live happy ever afterwards, without making some attempt to square things. The question is how to start. I'm hanged if I know, and so I came to you."
"Well," said Laurance thoughtfully, "there's a hope of Monsieur Chance you know. In many ways you may stumble on clues even without looking for them, since this gang-if it exists-must carry on an extensive business. All you can do, Dan, is to keep your eyes and ears and nose open-the last for that scent, you know. On my part I shall write the letter, and publish it in the annex of The Moment. Then we shall see what will happen."
"Yes, I think that's about the best way to begin. Stir up the muddy water, and we may find what is at the bottom of the pond. But there's one thing to be considered, and that is money. If I'm going to hunt for these scoundrels I need cash, and to own up, Freddy, I haven't very much." "You're so beastly extravagant," said Laurance grinning, "and your private income goes nowhere."
"Huh! what's five hundred a year?"
"Ten pounds a week, more or less. However, there's your aviation. I hear that you take people flights for money?" Dan nodded. "It's the latest fashionable folly, which is a good thing for me, old son. I get pretty well paid, and it means fun."
"With some risk of death," said Laurance drily. "Well, yes. But that is a peculiarity of present-day fun. People love to play with death-it thrills them. However, if I am to hunt for the assassin of Sir Charles, I can't give much attention to aviation, and I repeat that I want money. Oceans of it."
"Would two thousand pounds suit you?"
"Rather. Only I'm not going to borrow from you, old man, thank you."
"I haven't that amount to lend," said Freddy, drily; "but you must have seen, if you read our very interesting paper, that our proprietor has offered a prize of two thousand pounds for a successful flight from London to York."
"A kind of up-to-date Dick Turpin, I suppose," laughed Dan, rising and stretching his long limbs. "Good, I'll have a shot, I may win."
"You will, if you use a Vincent machine."
"Vincent, Vincent? Where have I heard that name?"
"Everywhere if you know anything of the aviation world," snapped Laurance rather crossly, for at times Dan's indolence in acquiring necessary information annoyed him. "Solomon Vincent, who has been inventing airships and new-fangled aeroplanes for ever so long."
"Yes, yes! I remember now. He's a genius. Every one knows him." "Every one knows of him, except yourself; but no one knows him personally. He lives a secluded life up in Hillshire, on the borders of the moors, where he can find wide space for his experiments in aerial craft. I interviewed him a year ago, and-and-" Laurance blushed red. "Hullo, what's this?" asked Dan shrewdly. "Can it be that the inventor has a daughter fair?"
"A niece," retorted Laurance, recovering; "why shouldn't I be in love as well as you, Halliday? However, that doesn't matter."
"It matters a great deal to you."
"Never mind. What you have to do is to secure one of Vincent's machines and try for this race. If you win the prize you will have heaps of money to search for the gang. But why doesn't Miss Moon-"
"I don't take Lillian's money," said Dan curtly, and blushed in his turn. "It is a good idea, Freddy. How can I get hold of the machine?"
"I shall take you up to Hillshire next week, and you can see Vincent for yourself. He can talk to you, and-"
"And you can talk to the niece. What's her name?"
"Oh, shut up and get out," said Laurance, turning away, "you're interrupting my work."
"Going to write a letter to the beloved," said Dan, leisurely making for the door. "All right, old son, I'll go. You know my address, so write me when you want me. I'd like to see Vincent's machines, as I hear he has made several good improvements, and everything tells in a race. Salaam!"
"Keep your eyes open," Laurance called after him; "remember Monsieur Chance may prove to be our best friend." Dan departed, shrugging his shoulders. "I don't believe in heaven-sent miracles," were his last words. But they were wasted on Freddy, for that alert young man was already buried in his work. It was painful to witness such industry, in Halliday's opinion. In an inquiring frame of mind, the amateur detective strolled along Fleet Street, thinking of Lillian instead of keeping his wits about him, as Freddy had requested. It seemed impossible that he should strike on a clue without deliberately searching for it, which he did not feel inclined to do at the moment. Monsieur Chance, indeed! He was a mythical personage in whom this sceptical young man did not believe. Besides love dominated his thoughts to the exclusion of minor matters, and he dreamed about his darling all along the Strand. Thus he did not look where he was going, and stumbled into the midst of a Charing Cross crowd, where a motor had broken down after colliding with a 'bus. A policeman was conversing with the chauffeur and the 'bus driver, who were conversing abusively with one another. The crowd blocked the street and stopped the traffic in order to enjoy the conversation, which left nothing to be desired in the way of free language. Dan halted idly, as a spectator, not because he wished to be one, but for the very simple reason that he could not get through the crowd into Trafalgar Square. Thrust up against one man, and wedged in by two others, and surrounded by hundreds, he grumbled at the delay, and peered over shoulders to see when the incident would end. As he did so, he suddenly in his mind's eye saw a vision of Sir Charles lying dead in the well-lighted library. While wondering why he thought of the crime at this particular moment, he became aware that a familiar scent assailed his nostrils, the scent about which he had talked to Durwin and Tenson and Laurance. Nosing like a hound, he tried to find the person from whom it emanated, and almost immediately later the man turned, and Dan found himself face to face with Marcus Penn.
CHAPTER V
MUDDY WATER
The secretary of the late Sir Charles Moon smiled irresolutely when he recognized Dan. That young gentleman, who thought Penn a weak-kneed idiot, had never taken much notice of him, but for the fact that he was perfumed with the unusual scent would not have spoken to him now. But as he looked at the lank creature with his yellow face, and scanty moustache, he guessed that he was exactly the effeminate sort of person who would use perfume. What he wished to know was why he affected this particular kind of fragrance, and whence he obtained it. To gain the information he pretended a friendliness for the man he was far from feeling. Dan, strong, virile, and self-confident, was not altogether just to Penn, who was not responsible for his pallid looks and weak character. But Halliday was not a perfect individual by any means, and had yet to learn that the weak are meant to be protected and helped instead of being despised. "You here, Mr. Penn?" said Dan, thus formal to mark the difference between them. "Yes," replied the man in his faint hesitating voice, and, as they moved out of the crowd, Halliday smelt the weird perfume more strongly than ever shaken from Penn's clothes by his movements. "I stopped to look at the accident."
"A very ordinary one," rejoined Mr. Halliday, with a shrug. "By the way, I have not seen you since the funeral of Sir Charles. What are you doing now, if I may ask?"
"I am secretary to Lord Curberry."
"Oh!" The reply gave Dan something of a shock, for he did not expect at the moment to hear his rival's name. But then the whole incident of meeting Penn and smelling the incriminating perfume was strange. Monsieur Chance had proved himself to be an actuality instead of the mythical personage Dan had believed him to be. It was certainly odd that the meeting had taken place, and odder still that Penn should prove to be the servant of Curberry. As Halliday said nothing more than "Oh!" the other man stroked his moustache and explained. "Sir John got me the post, Mr. Halliday," he said, with his shifty eyes anywhere but on Dan's inquiring face. "I was quite stranded after Sir Charles's unexpected death, and did not know where to turn for employment. As I support a widowed mother, the situation was rather serious, so I took my courage in my hands and went to Sir John. He was good enough to recommend me to Lord Curberry, and I have been with his lordship for a month, more or less."
"I congratulate you, Mr. Penn, and Lord Curberry, also. Sir Charles always said you were an excellent secretary," Dan stopped as Penn bowed his acknowledgments to the compliment, and cast a keen side glance at the man. They were walking through Trafalgar Square by this time, passing under the shadow of Nelson's Column. "Do you know what I was thinking of when behind you in the crowd yonder, Mr. Penn?" he asked abruptly, and it must be confessed rather undiplomatically, if he wished to get at the truth. "No," said the secretary, with simplicity and manifest surprise. "No, Mr. Halliday, how can I guess your thoughts?"
"I was thinking of the murder of your late employer," said Dan straightly. Penn blinked and shivered. "It's a horrible subject to think about," he remarked in a low voice. "I can scarcely get it out of my own thoughts. I suppose the sight of me reminded you of the crime, Mr. Halliday?"
"Scarcely, since I was behind you, and did not recognize you until you turned," replied Dan, calmly, and the other appeared to be surprised. "Then how-" he began, only to be cut short. "It's that scent."
"Scent!" echoed Penn nervously, but manifestly still surprised. "I don't understand exactly what you mean, Mr. Halliday. I like scent, and use much of it." Dan's lip curled. "So I perceive. But where did you get the particular scent you are using now, may I ask?" Something in his tone annoyed the secretary, for he drew himself up and halted. "I don't know why you should criticize my tastes, Mr. Halliday."
"I'm not criticizing them, and don't jump down my throat. But you reek of some strange perfume, which I last smelt-" He paused. "You cannot have smelt it anywhere," said Penn indifferently. "What do you mean by that exactly?" asked Dan with considerable sharpness. Penn resumed his walk and drew his light eyebrows together. "I am willing to explain as soon as you tell me why you speak of the scent."
"Hang it, man," rejoined Halliday, dropping into step, "any one would notice the scent and speak of it since it is so strong."
"Oh" – Penn's brow cleared-"I understand now. You have taken a fancy to the scent and wish me to get you some." Halliday was about to make an indignant denial, when he suddenly changed his mind, seeing a chance of learning something. "Well, can you get me some?"
"No," said Penn coolly; "I cannot. This is a particular perfume which comes from the Island of Sumatra. I have a cousin there who knows that I like perfumes, and he sent me a single bottle."
"Can't I buy it anywhere?"
"No, it is not to be obtained in England," said Penn curtly. "In that case," said Halliday slowly, "it is strange that I should have smelt the same perfume on the clothes of Sir Charles after his death."
"Did you?" Penn looked surprised. "That is impossible. Why, Sir Charles detested scents, and I never dared to use this one until I left him for the night."
"You used it on the night of the murder?"
"Of course. I used it every night when I left Sir Charles. On that evening he sent me away with my usual batch of letters, and was going down to the House later. I would not have seen him until the next morning, so I took the opportunity to indulge in this taste."
"Then how did Sir Charles's clothes become impregnated with it?"
"I am unable to say. Why do you ask? Surely" – Penn turned an alarmed face towards the speaker, and looked yellower than ever-"surely you do not suspect me of keeping back anything from the police likely to lead to the detection of the assassin."
"Ask yourself, Mr. Penn," said Dan coldly. "I and Inspector Tenson and Mr. Durwin smelt this particular perfume on the clothes of the dead man, and I do not mind telling you that the police consider it something of a clue."
"A clue to what? To me? It must be, since I alone possess this scent. I certainly came into the library when summoned by Mr. Durwin, and I helped to look after Sir Charles. As I was strongly perfumed with the scent it is not impossible that my employer's clothes took what, doubtless, you will call the taint. I think," ended Penn in a dignified manner, "that such is the proper explanation. You have found a mare's nest, Mr. Halliday."
"Upon my word, I believe I have," said Dan, quite good-humoredly, "but you must forgive me, Mr. Penn. Inspector Tenson agreed with me that the fly and the scent were clues."
"About the fly I know nothing," said the secretary positively, "but this scent is not to be had in England, and Sir Charles's clothes could only have gathered the fragrance from mine. If Inspector Tenson suspects me-"
"No, no, no!" interrupted Halliday quickly. "I assure you that he does not."
"He would if you told him of our meeting," retorted Penn as they passed into Piccadilly Circus, "and as I don't like even a suspicion to rest on me, Mr. Halliday-for my good name is my fortune-I shall go and see him and explain the whole circumstance. Indeed, if he wishes it, I shall give him the bottle which my cousin sent me from Sumatra, and never shall I use the scent again. I do not like these injurious suspicions."
"Don't make a mountain out of a mole-hill," said Dan, drily; "if I have hurt your feelings, I apologize."
"I accept your apology only on condition that you accept my explanation." Dan inwardly chuckled at Penn's dignity, but replied, readily enough. "Oh, yes, for if I did not accept your explanation I should not make any apology. You are probably right since the scent must have got on to Sir Charles's clothes from your own. The clue-as we took it to be-has ended in smoke."
"But don't you think that I should see Inspector Tenson and explain?"
"There is no need," Dan assured him, soothingly. "If the Inspector says anything about the scent, I shall explain; and, after all, it was I who suggested the perfume as a clue." "Would you like what is left of the bottle?" asked Penn, pacified by the very frank apology of the other. "No, thanks, I never use perfumes. I hate them."
