Some Buried Caesar

On the way to an agricultural fair north of Manhattan, Wolfe's car runs into a tree, stranding Wolfe and Archie at the home of the owner of a chain of fast-food cafés. A neighbor is later found gored to death; the authorities rule the death an accident but Wolfe deduces that it was murder. Lily Rowan, Archie's longtime girlfriend, makes her first appearance. This is one of several Wolfe plots that break one of Wolfe's cardinal rules, to never conduct business away from the Manhattan brownstone. It involves minor characters who appear in several other Wolfe novels, under different names and in different locales: the self-important police officer who tries to intimidate Archie, and the occasionally bumbling but politically attuned district attorney. The book's title is from The Rubaiyat of Omar Khayyam. - From Wikipedia
