He stopped to look at Fritz, who had appeared on the threshold. Wolfe glanced at the clock; it was seven-twenty-five. He said, “I’m sorry, Fritz. Three of us will dine, at eight o’clock. Will that be possible?”

“Yes, sir.”

“Good.—As I was saying, Mr. Hibbard, I would like to help make the readjustment as pleasant as possible for you, and at the same time serve my own convenience. The things I have just told you are the truth, but to help me in realizing the last one I shall need your co-operation. I mentioned twenty-four hours. I would like to have you remain here as my guest for that period. Will you?”

Hibbard shook his head, with emphasis. “I don’t believe you. You may have the typewriter, but you don’t have Paul Chapin as I do. I don’t believe you’ll get him to confess, ever in God’s world.”

“I assure you, I will. But that can be left to the event. Will you stay here until tomorrow evening, and communicate with no one? My dear sir. I will bargain with you. You were about to make a request of me. I counter with one of my own. Though I am sure twenty-four hours will do, let us allow for contingencies; make it forty-eight. If you will agree to stay under this roof incommunicado until Monday evening, I engage that at that time, if I have not done as I said and closed the Chapin account forever, you will be free to resume your whimsical adventure without fear of any betrayal from us. Do I need to add a recommendation of our discretion and intelligence?”

As Wolfe finished speaking Hibbard unaccountably burst into laughter. For a runt he had a good laugh, deeper than his voice, which was baritone but a little thin. When he had laughed it out he said, “I was thinking that you probably have an adequate bathtub.”

“We have.”

“But tell me this. I am still learning. If I refused, if I got up now to walk out, what would you do?”

“Well... you see, Mr. Hibbard, it is important to my plans that your discovery should remain unknown until the proper moment. Certain shocks must be administered to Mr. Chapin, and they must be well timed. There are various ways of keeping a desired guest. The most amiable is to persuade him to accept an invitation; another would be to lock him up.”

Hibbard nodded. “You see? What did I tell you? You see how people go ahead and do things they feel like doing? Miraculous!”
