In Too Many Cooks, Nero Wolfe actually leaves the confines of his New York brownstone and travels to West Virginia to speak at a gathering of the world's great chefs. When one of the chefs is murdered, Nero is called upon to determine just who did it. This is probably my favorite of the series so far. And, as with all of the books, there were some really great lines.
"He hated things that moved, and was fond of arguing that nine times out of ten the places that people were on their way to were no improvement whatever on those they were coming from."
