Flashfire: A Parker Novel (Unabridged‪)‬

In a Midwestern city, Parker calmly tosses a firebomb through a plate-glass window, while some newfound partners in crime take down a nearby bank. Making their getaway in the confusion, the bank robbers tell him two things: that this heist was only seed money for a much gaudier one, and that Parker has to loan them his share of the take.
Now Parker is rampaging through the American South, taking on a new identity as he goes, and planning his own assault on his former partners' next target, a spectacular jewelry heist in Palm Beach. But Parker didn't count on one unfortunate detail. A very bad and very stupid man knows his true identity, and wants him dead.
