don't think so," argued Darrel. "The one crime includes the other. Find out the motive of the woman in killing the man, and you will doubtless be led to discover the reason she was killed herself. I should begin from the clue of the initials."
"Perhaps I will," said Torry thoughtfully; "and failing that clue, I'll try the other."
"The other! What other?"
"Why," said the detective, looking directly at his companion, "the clue of the Blue Mummy."
CHAPTER III
MR. TORRY'S THEORY
"The Blue Mummy," repeated Darrel wonderingly; "what do you mean?"
"Why!" said the detective, "I should rather say, the clue of the two Blue Mummies. Here they are."
Out of his pocket, Torry produced two little clay images in the shape of mummies, each six inches in length, and coloured a deep blue. The lifeless faces, the swathings and bandages of the rigid forms, were perfectly modelled in clay, and on the breast of each was a representation of the sun rayed round with spiral flames. These idol-s--as they doubtless were--appeared to be of great antiquity, and were, undoubtedly, fine specimens of ceramic art. That the relics of a dead and gone civilisation should be connected with a modern criminal case, amazed Frank not a little.
"Egyptian workmanship without doubt," said he, examining one of the little figures, "although I am not learned in such matters. Where did you get them?"
"One was found in the pocket of the dead woman, the other on the ground near the body of the man. Another proof, to my mind, that there is a connection between the two crimes."
"Curious," murmured Darrel, his eyes fixed on one of the images. "I wonder what they symbolise. If we could learn we might discover the motive for this double crime."
"You don't know the meaning of these idols, I suppose, sir?"
Darrel shook his head. "No," said he, "but I am acquainted with an Egyptologist who might tell us all about them. I'll take them to him if you like, Mr. Torry."
"Take one, as they are precisely the same," replied the prudent detective, "and ask your friend what it represents; some god no doubt. But look here, Mr. Darrel," added Torry in a livelier tone, "I have answered all your questions, now you must reply to some of mine."
"Willingly. What is it you wish to know?"
"Tell me all that took place, from the time you saw the red-headed man in Drury-lane until the moment you discovered his dead body."
To this natural request Darrel assented at once, and narrated his Saturday night, or rather Sunday morning, adventure in Drury-lane. The detective listened in silence, his keen eyes fixed on the narrator, and when Darrel ceased he put a series of questions to him, noting the replies to the same in a little book. It may be here remarked that Mr. Torry used a cypher known to no one but himself; so, even if he lost his pocket-book, there was no chance of its contents becoming known.
"You say that this man spoke like an educated gentleman?"
"Certainly; his accent was most refined."
"At what time did he address you first?"
"Shortly after twelve o'clock."
"How long did it take you to walk to Mortality-lane?"
"Ten minutes, more or less, I should think. Altogether it was twenty minutes past midnight when he left me."
"The drive to throw you off the scent took some time, I suppose?"
Darrel calculated. "About forty minutes, more or less," he said. "We got back to Mortality-lane shortly after the clock struck one. Then I had some talk with the cabman who had misled me, according to instructions, and I remember him saying he was going home, because it was after one o'clock."
"Then the murder must have been committed between half-past twelve and one o'clock in the morning?"
"Yes, I am sure it was. Bike and myself found the corpse shortly after one o'clock. It was still warm," said Darrel, with a shudder.
"The red-haired man was not at his ease with you, I suppose?"
"On the contrary, he kept a safe distance between us, and all the time he had his right hand in the breast of his coat."
"Oh, that was a revolver," said Torry indifferently, "we found it when the body was searched. But," added the detective with emphasis, "we did not find the valuables he carried."
"Valuables! What valuables?"
"I can't say. Papers, or jewels, or money; one of the three, I am certain!"
"But what reason have you to think that he carried valuables?" asked Darrel becoming the questioner in his turn.
Torry shrugged his plump shoulders. "He wouldn't have carried a revolver else," he remarked.
"That might have been to protect himself against bad characters, such as he suspected me to be," objected Frank captiously.
"No," replied Torry decisively, "I don't think so. He purposely assumed shabby clothes so that there would be nothing in his appearance to suggest that he was worth robbing. A threadbare vagrant slinking through the midnight streets, would attract no notice save that of a policeman, and he would not dare to use his revolver in that case."
"Why not?" asked Darrel rather obtusely.
"Because he would have run the risk of arrest, and his real name--which, obviously, he was anxious to conceal--would have come out. No, Mr. Darrel, the dead man had some valuable object, or perhaps, some money, in his possession, and carried the revolver to protect himself against possible robbery; and that supposition," concluded the detective, rubbing his plump knees "efbrings me to my theory."
"To your theory?"
Torry pointed to the image held by Darrel, "To be precise I should say to my clue--the clue of the Blue Mummy."
"I don't quite see how you bring this into the matter."
"Well," said Torry, "it is all theory, I admit; but my belief is this: The red-haired man carried some valuables, money, jewels, or papers, to the woman in Mortality-lane. When he delivered up the jewel--for the sake of clearness we'll say jewel--she gave him the Blue Mummy."
"Why?"
"As a kind of receipt, I suppose. Red-hair took the image in his right hand intending to put it into his pocket. At that moment, having the jewel in her possession, the woman struck at him with the knife she carried, and he, thrusting out his left hand to protect himself, caught at and tore the lace of her mantle. Naturally, as he had received his death-wound--he was stabbed to the heart, you know--the Blue Mummy fell from his clasp and was found on the ground near his body."
"Very ingenious," admitted Darrel sceptically, "But pure theory."
"No doubt. Every detective must theorise to some extent, in order to have a basis to work on. But you must admit that my theory is a feasible one."
"Certainly, but as regards this second Blue Mummy."
"Oh! I believe that, after committing the murder, this woman went off to meet her assassin near Cleopatra's Needle. She gave him the jewels which he doubtless expected to receive, and he gave her, also as a receipt, the image of the second mummy. This she put in her pocket, and was turning away when he stabbed her. Then he tried to throw the body into the water, but, being interrupted, fled, leaving the work undone."
"But," objected Darrel, finding flaws with the true instinct of criticism, "why do you suppose that the assassin gave this image to his victim? in the other case when she was the assassin, she gave the mummy to red-hair; it is possible, therefore, that she had this second one in her pocket."
"Not if my theory is correct," retorted Torry, nettled. "The woman gave
