Firebreak: a Parker novel by Richard Stark

In ten words or less: Hit man targets Parker while Parker plans art heist.

Review: While Parker is deciding whether to take on a job at a Montana hunting lodge--stealing valuable paintings from a secret vault with state-of-the-art security--someone has sent a hit man to his home. Parker got to the hit man first, but when news of the failed hit got back to the employers, another hit man was sure to follow.
Parker needed to settle the score with whoever was hiring the shooters, but he was stsill undecided about whether to throw in with the gang planning the art heist. The guy who'd be responsible for disabling the alarms, Lloyd, was an amateur, a white-collar criminal who was hung out to dry by his former partner, and he wanted revenge.
Why bother? Fast faced, page-turning action from Stark, aka Donald Westlake. Parker is always one step ahead of both the other bad guys and the cops.
