Hutch Vanek and the Filthy Saint

Things are bad enough for Hutch. He's divorced, unemployed, and living in a van. But he has a lead on a job, the kind of job he's always wanted--a chance to write for a living. Things are looking up, until his first interview turns up dead in the gutter with a .44 caliber hole in his face. Why would somebody murder the head of a Salvation Army parish? Who kills a saint?
