Death Wears a Red Hat — William X. Kienzle

A self-appointed executioner is stopping crime dead ...and leaving the heads of Detroit's kingpins of crime in Catholic churches. One head is found swinging from the rafters, inside a Cardinal's hat. Another tops a statue of St. Cecilia. FATHER BOB KOESLER--parish priest, Sunday golfer, mystery buff--helps the police piece together the puzzle. But will his priestly conscience stop him from revealing the identity of the murderer?
