Too Many Cooks. Rex Stout.

Too Many Cooks.
Rex Stout

This is a Nero Wolfe mystery. Wolfe is a big fat detective, and his stories generally have a gastronomical lean.

The great chefs of the world hold a conference, and one of them is murdered. The killer is very easy to identify, and although this is written as a Christie-like mystery, you get the feeling that Archie Goodwin, Nero’s sidekick, would rather be (or thinks he is) in a hard-boiled detective novel. At any rate, his very dry, sarcastic wit carries the story along, and Nero Wolfe himself is more of a plot device than a truly interesting character (although he does have his share of good lines.)
