Query: Nero Wolfe is always a good read

This is one of his first. I've read them all, several times each. Even tho this is not his best, Rex Stout still writes far better than most writers today. His books are very funny and the plots entertaining. Closest I've come to finding his successor is Deadly Diamonds, by Pamela Troutman.
