Detective Kiley Russell is investigating a serial killer who is targeting firefighters. When she arrives at the latest crime site, she is disconcerted to see fireman Collier McClain, who sets off unwanted fires of passion. She distrusts his playboy reputation; Collier is down on commitment because of his past. But since he is now fire inspector, they will have to work together to solve the mystery. Melting Point (3) by Debra Cowan has good details about firefighters and fire investigations along with a real mystery. Kiley's aversion to Collier does seem extreme, since they have no history, but their relationship grows logically.
