He shook his head. “No, Miss Geer. It is no great distinction not to be a coward, but I can claim it. Not cowardice. Conceit. I am insufferably conceited. I was convinced that the person who killed Mr. Jensen would be equally daring, witty, and effective in dealing with me. Should I be killed, I doubted if the murderer would ever be caught. Should another be killed in my place, I would still be alive to attend to the matter myself. Justified conceit, but still conceit.” He turned abruptly to me. “Archie, get Inspector Cramer on the phone.”

They both started talking at once, with vehemence. I watched them from a corner of an eye while dialing. Wolfe cut them off.

“If you please! In a moment I shall offer you an alternative: the police or me. Meanwhile Mr. Cramer can help. One of you, of course, is putting all this on; to the other I wish to say that you might as well sit down and resign yourself to some inconvenience and unpleasantness.” He glanced at Hackett. “If you want to get away from this uproar, there is your room upstairs...”

“I think I’ll stay here,” Hackett declared. “I’m a little interested in this myself, since I nearly got killed.”

“Cramer on,” I told Wolfe.

He lifted his phone from the cradle. “How do you do, sir. No. No, I have a request to make. If you send a man here right away, I’ll give him a revolver and a bullet. First, examine the revolver for fingerprints and send me copies. Second, trace the revolver if possible. Third, fire a bullet from it and compare it both with the bullet I am sending you and with the bullets that killed Mr. Jensen and Mr. Doyle. Let me know the results. That’s all. No. Confound it, no! If you come yourself you will be handed the package at the door and not admitted. I’m busy.”

As he hung up I said, “The number has been filed off of the gun.”

“Then it can’t be traced.”

“No, sir. Does Cramer get the handkerchief too?”

“Let me see it.”
