'Stop it!' Wolfe commanded. 'I know what I'm doing! There is no occasion for panic. Mr. Cramer, there is an excellent reason why that door must not be opened. If Archie releases you, will you listen to it? No? Then, Archie, hold him. This is a fumigating room where we use ciphogene, a gas which will kill a man by asphyxiation in two minutes. The pipe runs from a tank in the potting room and the valve is in there. This morning I closed the outlet of the pipe in this room, and removed the plug from an outlet in the potting room. So if Mr. Dill has opened that valve in the potting room, he is dead, or soon will be. And if you batter a hole in that door I won't answer for the consequences. We might get out quickly enough and we might not.'
'You goddamn balloon,' Cramer sputtered helplessly. It was the first and only time I ever heard him cuss in the presence of ladies.
I unwrapped myself from him and stepped back. He shook himself and barked at Wolfe:
'Are you going to just sit there? Are we going to just sit here? Isn't there-can't you call someone-'
'I'll try,' Wolfe said placidly. He lifted the osmundine fork and thumped the floor with it, five times, at regular intervals.
Lewis Hewitt murmured, believe it or not, apparently to Theodore, 'I was in the dramatic club at college.'
Chapter 10
All right, I'll buy you a medal,' Inspector Cramer in utter disgust.
Five hours had passed. It was six thirty that evening, and the three of us were in the office. I was at my desk, Cramer was in the red leather chair, and Wolfe was seated behind his own desk, leaning back with his fingertips touching on top of his digestive domain. He looked a little creasy around the eyes, which were almost open.
Cramer went on sputtering: 'Dill was a murderer, and he's dead, and you killed him. You maneuvered him into the potting room with a fake phone call, and he took the bait and bolted the door to the fumigating room and opened the valve. And then why didn't he walk out and go home? How did you know he wouldn't do that?'
'Pfui,' Wolfe said lazily. He grunted. 'Without waiting four minutes to make sure the ciphogene had worked? And leaving the door bolted, and the valve open? Mr. Dill was a fool, but not that big a fool. After a few minutes he would have closed the valve and opened the door, held his nose long enough to take a look at us and make sure we were finished, and departed, leaving the door closed but not bolted to give it the appearance of an accident. And probably leaving the valve a bit loose so it would leak a little.' Wolfe grunted again. 'No. That wasn't where the thin ice was. It was next thing to a certainty that Mr. Dill wouldn't decamp without having a look inside at us.'
'You were sure of that.'
'I was.'
'You admit it.'
'I do.'
'Then you murdered him.'
'My dear sir.' Wolfe wiggled a finger in exasperation. 'If you are privately branding me to relieve your feelings, I don't mind. If you are speaking officially, you are talking gibberish. I could be utterly candid even to a jury, regarding my preparations. I could admit that I plugged the outlet in the fumigating room, and opened the one in the potting room, so that it would be the latter, and not the former, that would be filled with ciphogene if Mr. Dill bolted that door and opened that valve. I could admit that I arranged with Mr. Hewitt to play his part, appealing to him in the interest of justice. He is a public-spirited man. And I discovered his weakness; he has always wanted to be an actor. He even gave me permission to mention his cane, and to recite that wild tale about him-which of course was true, though not true about him, but about Mr. Dill.
'I could admit that I arranged with Theodore also to play his part. He works for me and obeyed orders. I could admit that I had Fritz stationed in the room below, and my three thumps on the floor were a signal to him to make the telephone call for Mr. Hewitt, and the five thumps, later, told him to come upstairs and start the ventilating blowers in the potting room, which can be done from the hall. I could admit that I deliberately postponed the second signal to Fritz for three minutes after I learned that the door had been bolted; that I had previously released a minute quantity of ciphogene in the potting room and fumigating room so that Mr. Dill's nose would be accustomed to the smell and would not take alarm at any sudden odor in the potting room after he turned on the valve; that all my arrangements were made with the idea that if Mr. Dill should open that valve, thinking to murder all eight of us, he would die, I could admit all that to a jury.'
Wolfe sighed. 'But the fact would remain that Mr. Dill opened the valve of his own volition, intending to exterminate eight people, including you. No jury would find against me even for damage to your self- esteem.'
'To hell with my self-esteem,' Cramer growled. 'Why don't you send a bill to the State of New York for the execution of a murderer f.o.b. your potting room? That's the only thing you've left out. Why don't you?'
Wolfe chuckled. 'I wonder if I could collect. It's worth trying. I may tell you privately, Mr. Cramer, that there were several reasons why it would have been unfortunate for Mr. Dill to be brought to trial. One, it might have been difficult to convict him. Only a fairly good case. Two, the part played by Mr. Hewitt's cane would have been made public, and I had undertaken to prevent that. Three, Archie would have been embarrassed. He pulled the trigger and killed the man. Four, Miss Lasher would have committed suicide, or tried to. She's not very bright, but she's stubborn as the devil. She had decided that if she admitted having seen anything from her hiding-place in the corridor, she would have to testify to it publicly, her relations with Mr. Gould would have been exposed, and her family would have been dishonored.'
'They would have been exposed anyway.',
'Certainly, once you got hold of her. When Archie brought her to the potting room, with you there, she was a goner. That was the beauty of it. Mr. Dill knew she was bound to crack, and that coupled with the threat of being confronted with the garage man was what cracked him. It was a delicate situation. Among many others
