“There is no reason to tell me. I am not concerned.” He pointed to the knife and trowel, still on his desk. “Where did you get those things?”

“Then I’ll keep them in my room.”

“Do so. By all means. Please take a letter to Mr. Hoehn.”

No doubt it would have been, except for his vanity. Or perhaps it wasn’t vanity; it may be that the reason he permitted his privacy to be invaded again by brother Daniel was that he wanted to impress on him the desirability of getting the bill of the Fisher Laboratories paid as soon as possible. At any rate, when Daniel turned up some hours later, a little before seven that evening, Fritz was told to bring him to the office. At first sight of him I knew he had something, by the look in his eye and the set of his jaw. He tramped over to Wolfe’s desk and announced:

“My sister was murdered.”

“I guess I’m a little weak from excitement,” he said apologetically. “Then I had only an apple for breakfast, and I haven’t eaten anything since.”
