The Mystery Queen. Hume Fergus

in publishing his letter, which dealt with the mystery of Moon's death. As The Moment, including its extra letter-writing sheet, had a large circulation, and as it was a season devoid of news, the letter caused great discussions. It was sufficiently alarming to those who loved law and order, since it boldly announced that a gang of criminals existed which coldly and cautiously and deliberately employed its members to put people to death. The letter called attention to the fly-and that an artificial one-on Sir Charles's neck near the poisoned wound, and declared that such was the sign-manual of the accursed society. No mention was made of the scent, since Dan had explained what Penn had said to Laurance, and Laurance had accepted the explanation as valid. But there was quite enough in the letter to startle the most dull, especially when the writer called attention to the happening of various mysterious murders, and suggested that such were the work of this misguided set of people who constituted the unknown gang; finally, Freddy ended his letter by saying that Moon had knowledge of the gang, and had sent for a Scotland Yard official-name not given-to explain the whole matter, when he met with his death. It was a fact, therefore, that the false Mrs. Brown was an emissary of the gang who had been sent to murder Sir Charles, and had performed her vile errand only too well. A postscript to the epistle invited discussion, and particularly called upon any person who knew of an artificial fly being found on a corpse to give evidence. In two days the sheet was filled with letters from various people, and the matter was much discussed. Some of the writers laughed at the idea of such a society existing in a civilized country such as England, while others expressed alarm and asked what the police were doing not to arrest the criminals. These last scribes evidently entirely forgot that no one knew where the central quarters of the gang were, and that the letter of Mr. Laurance was an attempt to root out the heart of the mystery. Those who appeared in print and aided the circulation of The Moment by buying their own lucubrations certainly did not help much. The generality of the letters were discursive and ornate, wandering very much from the point, and giving no positive information such as would assist Freddy's purpose. But three or four epistles drew attention to certain mysterious crimes, the perpetrators of which had never been brought to justice, and who were not even known. There was the case of a young girl found dead on the Brighton railway line, near Redhill, and who must have been thrown out of the train. Then some one wrote about a miser in the East End who had been strangled, and another person recalled the drowning of a well-known philanthropist in the Serpentine. A verdict of suicide had been brought in as regards this last victim, but the writer of the letter positively asserted that the philanthropist had not the slightest intention of making away with himself. Finally came a batch of letters concerning children who had been murdered. But only in one case did it appear that any fly was seen on the victim, and that was when a schoolmistress was stabbed to the heart while in bed and asleep. The assassin had entered and escaped by the window, and the victim's mother-who wrote the letter drawing attention to this case-had found the fly on her daughter's cheek. She had thought nothing of it at the time, and had brushed away the insect. But after the mention of the fly on Sir Charles Moon's neck, she remembered the incident. Also it turned out that the schoolmistress, had she lived, would have inherited a large sum of money. It was this last circumstance that suggested the intervention of the gang to murder the girl, so that someone else might inherit. But all the letters dealing with the various cases were vague, and no enlightening details could be given. All that could be said was that there were many unusual deaths, the mystery of which could not be solved. Laurance, reading the letters during the week of their appearance, felt sure that the gang existed, but he was more or less alone in his opinion. Even Dan was doubtful. "It seems such a large order for a number of people to band themselves together, to murder on this comprehensive scale," he objected; "and I don't quite see the object. Many of the victims mentioned in these letters are poor."

      "You seem to have changed your mind about the matter," said Laurance drily, "for when my letter appeared you were assured that there was such a gang."

      "Only because of Sir Charles's remarks to Durwin."

      "It was a pity Sir Charles was not more explicit," retorted Freddy crossly. "He had no time to be explicit," said Dan patiently, "since he died before he explained. But let us admit, for the sake of argument, that such a gang exists. Why should the members murder poor people?"

      "Folks have been murdered by way of revenge, as well as for money. And let me remind you, Dan, that four or five of these victims mentioned in the letters had money, or were about to inherit money. I am quite convinced," said Laurance, striking the table, "that there is such an association."

      "An association for what?"

      "You are very dull. To get undesirable people out of the way. Remember, in the reign of Louis XIV there were dozens of poisoners in Paris who undertook to kill people when engaged to do so. The reason was for revenge, or desire for money, or-or-or for other reasons," ended Laurance vaguely. "Hum!" Dan stroked his chin, "it may be as you say. Certainly Sir Charles was got rid of, because he knew too much."

      "About this gang," insisted Laurance, "since he was to see Durwin about the same. I am certain that such an association exists."

      "You said that before," Halliday reminded him. "And I say it again. At all events there is one thing certain-that we have learned from these letters of many mysterious crimes."

      "But only in one case was the fly discovered," objected Dan again. "That is not to be wondered at," replied the journalist; "the wonder is that such a small insect should be noticed at all. No one would ever think of connecting a fly, whether dead or alive, with the death. The mother of this schoolmistress did not, until your experience with regard to Moon was quoted in my letter. The fly business is quite ridiculous."

      "And perhaps means nothing."

      "Oh, I think it does, seeing that in Moon's case, the fly was artificial. Probably in the case of the schoolmistress it was artificial also, only the mother who noticed it did not make an examination. Why should she? I wonder the gang don't have a better trade-mark."

      "Perhaps the gang may think it would be spotted if it did."

      "Then why have any trade-mark at all," answered Laurance, sensibly. "If there is to be a sign, there should be some sensible one. If the fly was stamped on the skin, as the purple fern was stamped, there would be some sense in the matter. But a fly, artificial or real, is-" Freddy spread out his hands, for words entirely failed him. "Well," said Dan after a pause, "I don't know what to say, since everything is so vague. However, I shall assume that such a gang exists, and shall do my best to aid you to bring about its destruction, as that means my marriage to Lillian. To help, I must have money, so the sooner we get North and engage one of Vincent's machines with all the latest improvements, the better shall I be pleased." He moved towards the door, as they were in Laurance's rooms when this conversation took place, and there he halted. "I think, Freddy, you will have a chance of proving in your own person, as to the truth of your supposition regarding this gang!" "What do you mean?" asked Laurance somewhat startled. "Well," murmured Dan, "the gang knows you started the hunt for its destruction, as I expect the members read the papers. If that is the case you will be a source of danger, such as Sir Charles was and-"

      "I'll look after myself," interrupted Laurance grimly. "Well, if you don't, and the worst comes," said Dan agreeably, "I shall carefully examine your corpse for the celebrated fly."

      "I'll look after myself," said Laurance again, "and if you think I am going to give up doing business through fear of death, you are much mistaken. If I can find the gang and exterminate the gang, I'll get a much larger salary, and so will be able to marry Mildred."

      "Oh, that's her name, is it? Mildred Vincent! Is she pretty?" "You might not think so, since Miss Moon is your ideal," said Freddy, with a blush. "Mildred is dark and tall, and well-proportioned-none of your skimpy women, old man."

      "Lillian isn't skimpy," cried Halliday indignantly. "I never said she was. Let us call her fairy-like."

      "That's better. And your Mildred?" "You'll see her when we go North the day after tomorrow."

      "Good!" Dan nodded thankfully, "we go to Vincent the day after to-morrow?"

      "Yes. Meet me at a quarter to twelve at St. Pancras Station; the train leaves at mid-day and we change at Thawley for Beswick about four o'clock. I expect we'll arrive-all going well-at Sheepeak about six."

      "Good.
