" You have interrupted me four times, Mr. Cramer. My tolerance is not infinite. You would say, of course, that the message would not be published, and in good faith, but your good faith isn’t enough. No doubt Mrs. Nesbitt was assured that her name wouldn’t become known, but it did. So I reserve the message. I was about to say, it wouldn’t help you to find your murderer. Except for that one immaterial detail, you know all that I know, now that you have reached my client. As for what Mrs. Valdon hired me to do, that’s manifest. I engaged to find the mother of the baby. They have been at that, and that alone, for more than three weeks—Mr. Goodwin, Mr. Panzer, Mr. Durkin, and Mr. Cather. You ask if I’m blocked. I am. I’m at my wit’s end. "
― Rex Stout , The Mother Hunt (Nero Wolfe #38)
