One of his ten favorite noir novels, as shared at Publishers Weekly:
The Shark-Infested Custard by Charles WillefordRead about another entry on the list.
This is a longtime favorite. Willeford said it was his own favorite of his novels. Set in the seventies, it describes four sociopathic swingers in Miami. Told in four parts, it begins with one of the characters needing sixty bucks to pick up a woman and an ensuing robbery that leaves two dead. The mayhem and hilarity continue from this. It is pure noir and reads almost like a Tarantino script. The title alone makes this minor gem worth tracking down.
