"The night after the interview—or it may have been the same night—I refer to the interview which Mr. Tarling had with the late Thornton Lyne—I was working late at the office. I was, in fact, clearing up Mr. Lyne's desk. I had occasion to leave the office, and on my return found the place in darkness. I re-connected the light, and then discovered on the desk a particularly murderous looking revolver.

"In the statement I made to you, sir," he turned to Tarling, "I said that that pistol had not been found by me; and indeed, I professed the profoundest ignorance of its existence. I regret to confess to you that I was telling an untruth. I did find the pistol; I put it in my pocket and I took it home. It is probable that with that pistol Mr. Lyne was fatally shot."

Tarling nodded.

"I hadn't the slightest doubt about that, Milburgh. You also had another automatic pistol, purchased subsequent to the murder from John Wadham's of Holborn Circus."

Mr. Milburgh bowed his head.

"That is perfectly true, sir," he said. "I have such a weapon. I live a very lonely kind of life, and——"

"You need not explain. I merely tell you," said Tarling, "that I know where you got the pistol with which you shot at me on the night I brought Odette Rider back from Ashford."

Mr. Milburgh closed his eyes and there was resignation written largely on his face—the resignation of an ill-used and falsely-accused man.

"I think it would be better not to discuss controversial subjects," he said. "If you will allow me, I will keep to the facts."

Tarling could have laughed at the sublime impertinence of the man, but that he was growing irritable with the double strain which was being imposed upon him. It was probable that, had not this man accused Odette Rider of the murder, he would have left him to make his confession to Whiteside, and have gone alone in his hopeless search for the taxicab driven by Sam Stay.
