All of the William X. Keinsle [[Spelling of the last name might be wrong) murder mysteries place in Detroit. William X. Keinsle was an ex Catholic priest. ALL of his books surround Detroit [[a LOT) and have a Catholic spin on them. One of them [[The Rosary Murders) was made into a movie with Donald Sutherland as the main character, and was filmed in Detroit. Check them out.

There was also another book by Elmore Leonard called Freaky Deaky. Not such a great book, but the setting too was Detroit.

Hope this helps you.
