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 the mummy to red-hair as a receipt for the jewel; in her turn she received the second figure on delivering up the jewel to her assassin.
"Well, admitting as much, why having obtained what he wanted, should he have killed her?"
"Find out that and I'll find the murderer," said Torry grimly. "Well, Mr. Darrel, here is your detective novel in real life. What do you think of the plot provided by chance?"
"Plot!" echoed Darrel. "I should rather call it a riddle--and one quite impossible to guess."
"Ah, sir, you'll never make a detective if this mystery discourages you so early."
"But I don't see how you intend to begin."
"Well," said Torry, "in the first place there is the clue of the initials. I'll go to that shop in Bond-street and find out what the letters 'J.G.,' stand for. Thus I may arrive at the identity of the man, and thereby be able to learn about his past life. In his past life I may discover the motive for the crime. In itself the marked shirt is a good starting point, but there is also the clue of the four-wheeler."
"The four-wheeler?" repeated Frank. "The one driven by Henry which the red-haired man used as a blind, or the second owned by Bike in which I followed?"
"Neither. I am alluding to the third cab which was not on the stand when you returned at one o'clock."
"I don't see what that cab has to do with the business."
"Mr. Darrel! Mr. Darrel!" cried Torry gently. "You may be a good novelist, but, if you'll pardon my saying so, sir, you are a very bad detective. Is it not reasonable to suppose that the woman, anxious to get as far as possible from the scene of her crime would come up Mortality-lane and jump into the third cab? Also you must not forget that she had a rendezvous at Cleopatra's Needle, and, perhaps had to drive quickly to be in time."
"Yes; but coming into contact with a cabman she ran the risk of being--recognised. She must have known that when the murder was discovered the police would probably guess her flight in the four-wheeler, and inquire about her from the driver. He would give her description and----"
"Oh, that is very well!" said Torry, dismissing this objection with a wave of his plump hand, "but the woman never guessed for a moment that chance would intervene; and that by means of her death we should obtain evidence of her crime. She thought she would escape scot-free; also I daresay she was disguised. Or it might be that she was too agitated to pay attention to the risk she ran.
"Anyhow, I am certain that she used the third cab to get away; and I am going to look up the driver."
"How will you find him?"
"By questioning Henry and Bike. Moreover, he may be on the cab-stand himself. I tell you what. Mr. Darrel," cried Torry, getting on his short legs, "let us make a division of labour. You go to Harcot and Harcot in Bond-street to find out what is the name attached to the letters, 'J.G.,' and I'll see to the cabman."
"Very good, Mr. Torry. When and where am I to see you?"
The detective pencilled an address on his card, and threw it across the table. "My private office, where we won't be disturbed," said he. "Eighty Craven-street, Strand. Come at four o'clock this afternoon. By the way, you might then be able to give me some information about the idol there."
"I'll try," said Darrel. "My friend lives near the British Museum, so I shall have time to run up and see him. But there is one thing you are not certain of yet."
"Sir," replied Mr. Torry drily, "there are many things of which I am not certain. But this special thing----"
"You don't know if the individual who killed the woman at Cleopatra's Needle is male or female."
"A male--a man, I'll stake my professional reputation on it."
"Why are you so sure?"
"Why?" echoed the detective, "because the woman ran too great a risk in committing the murder--she would only risk so much for a man."
