Nero Wolfe's favorite drink, beer, is not a beverage you can come to like on the first taste. You will find beer bitter and repugnant, but if you keep at it you will eventually begin to tolerate it, then to like it. So it is with Nero Wolfe. At first taste you will find him arrogant, eccentric, and thoroughly unlikeable. Keep at him. Because Rex Stout chose the novella as the format for most Wolfe stories you can read the stories at a sitting. After three novellas you will come to tolerate the corpulent crimefighter. After five, you will even come to have some affection for him.
"The Second Confession" might better be named "The Second Confrontation," because Wolfe faces his archnemesis, Arnold Zeck, for the second time. ("And be a Villain" chronicled the first confrontation). When Sherlock Holmes discovered the existence of Professor Moriarty, he immediately undertook to destroy the professor's criminal empire. When Nero Wolfe discovered the existence of Arnold Zeck, he immediately began to avoid Zeck at all costs. Holmes' course of action led to the Reichenbach Falls. Wolfe's led -- you'll have to find out in the final novella of the trilogy, "In the Best Families." Suffice it to say that Wolfe undertakes to expose a communist, runs afoul of Arnold Zeck, gets his orchids machine-gunned, and winds up trying to solve a murder for Zeck. Along the way Archie gets in deep trouble with the local constabulary, Wolfe confounds the police, the two manage to outright break several laws, and they severely bend a few more.
