The fifteen best chefs in the world have invited Nero Wolfe to their conference. When one of them is ironically murdered with a carving knife, the hefty private investigator agrees to find the killer. However, only under one condition: he demands a secret sausage recipe as his fee. Everyone knows that too many cooks spoil the broth, but it shouldn't lead to murder and mayhem. Yet that is exactly what's on the menu at a gathering of the world's top chefs. Nero Wolfe has been lured from his New York townhouse to a chic spa to give the opening speech. He never expected to have to search for a murderer alongside his assistant Archie amidst the exquisite courses of haute cuisine. A murderer who would be all too happy to prepare the great private investigator's last supper.
