“The League of Frightened Men” by Rex Stout.

One of the earliest, and best, of the Nero Wolfe mysteries.

As a young man, an author was crippled in a hazing accident. While he’s gone on to become a successful writer, many of his classmates feel he is planning vengeance.

They see hints and clues to his evil intentions in the books he writes.

Fun read and an interesting look at the times it was written in.
