Wolfe went on, "I'll answer your charge that it's a trick. What if it is? Are you in a position to condemn tricks? As a matter of fact, I do know, from the evidence of my own eyes, that the bull was Buckingham. I had the opportunity to ob- serve him minutely. Remember that I have studied the official sketches. Buckingham had a white patch high on his left shoulder; Caesar had not. The bull in the pasture had it. The white shield on Buckingham's face extended well below the level of the eyes; on Caesar it was smaller and came to a point higher up. Not only did I see the face of the bull in the pasture on Monday afternoon, but that night I examined it at close range with a flashlight. He was Buckingham. You know it; I know it; and if I can help a jury to know it by per- forming a trick with sketches I shall certainly do so. With Mr. Goodwin and Miss Rowan to swear that they saw me making them, I think we may regard that point as estab- lished."
"What else?"
"That's all. That's enough."
McMillan abruptly stood up. I was on my feet as soon as he was, with my gun in sight. He saw it and grinned at me without any humor, with his gums showing. "Go ahead and stop me, son," he said, and started, not fast but not slow, for the door. "Make it good though."
I dived past him and got to the door and stood with my back against it. He halted three paces off.
Wolfe's voice came, sharp, "Gentlemen! Please! If you start a commotion, Mr. McMillan, the thing is out of my hands. You must realize that. A wrestling match would bring people here. If you get shot you'll only be disabled; Mr. Goodwin doesn't like to kill people. Come back here and face it. I want to talk to you."
McMillan wheeled and demanded, "What the hell do you think I've been doing for the past month except face it?"
"I know. But you were still struggling. Now the struggle's over. You can't go out of that door; Mr. Goodwin won't let you. Come and sit down."
McMillan stood for a minute and looked at him. Then slowly he moved, back across the room to his chair, sat, put his elbows on his knees, and covered his face with his hands.
Wolfe said, "I don't know how you feel about it. You asked me what else. If you mean what other proof confronts you, I repeat that no more is needed. If you mean can I offer salve to your vanity, I think I can. You did extremely well. If I had not been here you would almost certainly have escaped, even the stigma of suspicion."
