Wolfe drank, and put his glass down. "I know. I can see the open jaws of the waiting beasts." He thumbed at Perry. "This one here in front. But let him wait a litde longer. Let us go on to last evening. That is quite simple. We are not concerned with the details of how Mr. Walsh got to see Mr. Perry at his office yesterday afternoon; it is enough to know that he did, since he phoned Lord Clivers that he had found Rubber Coleman. Well, there was only one thing for Mr. Perry to do, and he did it. Shortly after half past six o'clock he entered that building enclosure by one of the ways we know of- possibly he is a member of the Orient Club, another point for inquiry- crept up on old Mr. Walsh and shot him in the back of the head, probably muffling the sound of the shot by wrapping the gun in his overcoat or something else, moved the body to the vicinity of the telephone if it was not already there, left by the way he had come, and drove rapidly-"
"Wait a minute!" Cramer broke in, gruff. "How do you fit that? We know the exact time of that shot, two minutes to seven, when Walsh called you on the phone. And you heard the shot. We already know-"
"Please, Mr. Cramer." Wolfe was patient. "I'm not telling you what you already know; this, for you, is news. I was saying, Mr. Perry drove rapidly downtown and arrived at this office at exactly seven o'clock."
Hombert jerked up and snorted. Cramer stared at Wolfe, slowly shaking his head. Skinner, frowning, demanded, "Are you crazy, Wolfe? Yesterday you told us you heard the shot that killed Walsh, at six-fifty-eight. Now you say that Perry fired it, and then got to your office at seven o'clock." He snarled, "Well?"
"Precisely." Wolfe wiggled a finger at him. "Do you remember that last night I told you that I was confronted by a difficulty which had to be solved before anything could be done? That was it. You have just stated it. Archie, please tell Saul to go ahead."
I got up and went and opened the door to the front room. Saul Panzer was sitting there. I called to him, "Hey, Mr. Wolfe says to go ahead." Saul made for the hall and I heard him going out the front door.
