Wolfe sighed. "Must we start yapping again?" He wiggled a finger at the District Attorney. "I offered you a bargain, sir. I said if I could get replies to a few questions I would consider them and would then do what I could for you. Do you think I can consider them properly at this time of night? I assure you I cannot. I am not quibbling. I have gone much further than you gentlemen along the path to the solution of this puzzle, and I am confronted by one difficulty which must be solved before anything can be done. When it will be solved I cannot say. I may light on it ten minutes from now, while I am undressing for bed, or it may require extended investigation and labor. Confound it, do you realize it will be dawn in less than four hours? It was past three when I retired last night." He put his hands on the edge of his desk and pushed his chair back, rose to his feet, and pulled at the comers of his vest where a wide band of canary-yellow shirt puffed out. "Daylight will serve us better. No more tonight, short of the rack and the thumbscrew. You will hear from me."
Cramer got up too, saying to Hombert, "He's always like this. You might as well stick pins in a rhinoceros,"

WHEN, about a quarter after nine Wednesday morning, I went up to the plant rooms with a message, I thought that Wolfe's genius had at last bubbled over and he had gone nuts for good. He was in the potting room, standing by the bench, with a piece of board about four inches wide and ten inches long in each hand. He paid no attention to me when I entered. He held his hands two feet apart and then swiftly brought them together, flat sides of the two pieces of board meeting with a loud clap. He did that several times. He shook his head and threw one of the boards down and began hitting things with the other one, the top of the bench, one of its legs and then another one, the seat of a chair, the palm of his hand, a pile of wrapping paper. He kept shaking his head. Finally, deciding to admit I was there, he tossed the board down and turned his eyes on me with ferocious hostility –
"Well, sir?" he demanded.
