"Of course. It is not play with me as it is with you, but work; and I have to earn my bread and butter. Guided by the evidence we have in hand, I intend to proceed immediately. The victims are dead and buried; but the truth about them is not known. It is my duty to find out and punish the wrongdoers." "The wrongdoer, you mean," said Darrel, speaking in the singular. "We know who killed Mr. Grent." "Pardon me, Mr. Darrel, but that is just what we do not know." "The woman who was murdered----" "Did not kill the banker. No, I am sure of it. A female of her slight build would not have had the muscular energy to drive a weapon through cloth and wool straight into the heart of a strong man so as to kill him at the first stroke. A pistol, yes--for that weapon is as fatal in the hands of a woman as in those of a man; but a strong, long, steady stroke, involving unusual muscular exertion--to say nothing of the nerve power necessary. No, Mr. Darrel; I decline to believe the woman guilty. Depend upon it she was a victim, not an assassin." "Well," said Darrel quietly, "victim, or not, she was certainly an accomplice, else she would not have emerged from Mortality-lane with that man. You must admit that he must have killed Grent." "Of course," assented Torry calmly. "I thought as much from the time I heard the evidence of the third cabman. But what I wish to learn is, why the man required the woman to be present; and why did he permit her to interview her assassin by herself?" "How do you intend to obtain an answer to these questions?" "By finding out the name of the dead woman." "That is impossible!" declared Darrel emphatically. "By no means," replied Torry coolly. "In fact, I have done something already towards discovering the name; and my discovery narrows still more the ground which we are exploring. To be precise Mr. Darrel, everything points to the motive for the crime being discovered in Wray House." "In what way?" asked Frank, much astonished. "I'll answer your question by asking another, sir. Do you remember how we traced the name of Grent by means of the initials on his shirt?" "Yes. I remember quite well." "I resolved to apply that method to discover the dead woman's name." "But there were no marks on her linen," cried Darrel. "I know that," said Torry, rubbing his plump hands together, "but there was the name of a fashionable milliner stamped on the lining of the hat the dead woman wore. I went to see that milliner--Madame Vert, of Regent-street--and I discovered that the hat was made for Miss Sandoval." "For Donna Maria," said Darrel; then, on receiving a nod from the detective, he asked: "How did her hat come to be worn by the dead woman?" "I must find that out from the lady herself," replied Torry; "but you can see for yourself that this discovery connects Wray House with the crime." "Possibly. But does it never strike you that the Bank in Fleet-street may have some connection also? For my part, I mistrust Leighbourne."
