"You made mention to me of a plan, which would not only enable you to repay me what you owed me, but would result to our mutual advantage. You had, you said, secret access to the house of Samuel Boyd, who was in the habit of keeping there considerable sums of money, of which it would be easy to obtain possession. Without risk, without danger. You laid particular stress upon that."

"I did," said Dr. Pye, and the inscrutable smile which accompanied the words did not add to his confederate's composure.

"You needed a partner in the execution of your plan, a sleeping partner, you said, who would have nothing to do but to assist in removing the cash and valuables from his house to this, for which assistance he was to receive half the proceeds."

"Say spoil."

"The proceeds. I objected, not being willing to be a party to an act of personal violence. I am a peaceable man, and have made my money by peaceable means."

"By peaceable fraud."

"Why use harsh terms? All my transactions are legal, and protected by the law. In reply to my objection to a deed of violence you told me that you could in a moment render a sleeping man so utterly insensible and oblivious to all that was passing around him as to utterly remove every possible chance of risk. We were to enter the house when Samuel Boyd was asleep; you were to go into his chamber and render him insensible and unconscious."

"While you remained outside," said Dr. Pye, still with the inscrutable smile on his lips, "in happy ignorance of the sleeping man's fate."

"I object to these interruptions," said Dr. Vinsen, sulkily. "Finish the story your own way."

"I will. I informed you that Samuel Boyd, for an unknown purpose of his own, had been for some weeks past withdrawing large sums of money from the bank, and had been selling securities, and that I expected he would have in his safe on the night of March the 1st several thousand pounds, of which I offered you half for the tame part you were to play in the robbery. Your cupidity was aroused; you could not resist the bait, and you consented to become my partner in the crime. You do not like the terms I use; they are the correct terms. I am no canting psalm-singer; when I commit a crime I accept the responsibility; I do not shirk and whine; and as for the penalty, trust me for evading it. It was arranged that out of my share of the spoil I was to pay you what I owed you, so that you had a double interest in the success of the plan. The night arrived, and you were here, jubilant, expectant, greedy for the gold, but yet with a craven cowardice for which I despised you. However, you screwed your courage to the sticking point, and when all the lights in Samuel Boyd's house were extinguished I showed you how I obtained access to the premises. We entered in silence, and undetected; we made our way up the stairs and entered the office which contained the safe. You shook like an aspen, and I left you in the office and went alone into the bedroom, carrying a light. At that very moment Samuel Boyd awoke and started up in bed before I had time to press upon his face the handkerchief which I had prepared to render him unconscious. He sprang from the bed, and the handkerchief fell from my hand. One cry escaped his lips--only one, for my hand was on his throat. But he was strong, a more powerful man than I had conceived him to be, and he struggled with me so determinedly that we stumbled together into the office, where you stood, white-faced and trembling. By some means he got hold of a pistol, and fired two shots. One bullet went into the wall, where it was found by our good friend Remington, evidence of which was given by him and Lambert the detective at the inquest. Where the other bullet went has not yet been discovered. I thought I was struck, and for a moment my hold on Samuel Boyd relaxed. His eyes fell upon you, and your name escaped his lips, which was the first intimation I received that you had had transactions with him. That roused you to action, for you knew that if he were left alive you were doomed. You sprang upon him, and bore him to the ground. Then it was two to one. Our hands were at his throat. Whose fingers gave him the coup de grace?"
