On the theory that you can never have too many recommendations, here are two American comic satirists (mystery writers) whom you may or may not know.
Christopher Moore - Who has written Practical Demonkeeping, Coyote Blue, Bloodsucking Fiends, Island of the Sequined Love Nun, The Lust Lizard of Melancholy Cove, Lamb, Fluke, The Stupidest Angel, A Dirty Job, You Suck, and Fool. He lives in San Francisco.
Carl Hiaasen - who has some 30 books, two of which have been made into movies. His first "mystery" is called Tourist Season. One of Hiaasen's previous novels, Strip Tease, became a major motion-picture in 1996 starring Demi Moore, and directed by Andrew Bergman. Despite what some critics said, Hiaasen continues to insist that the scene featuring Burt Reynolds slathered from his neck to his toes with Vaseline is one of the high points in modern American cinema.
You may already know both these authors, but if not, I think you'd enjoy them.
