A Cool Breeze on the Underground — Don Winslow

Neal Carey is not your usual private eye. A graduate student at Columba University, he grew up on the streets of New York, usually on the wrong side of the law. Then he met Joe Graham, a one-armed P.I. who introduced him to the Bank, an exclusive New England institution with a sideline in keeping its wealthy clients happy and out of trouble. They pay Neal's college tuition, and Neal gets an education that can't be found in any textbook … from learning how to trail a suspect to mastering the proper way to search a room.

Now it's payback time. The Bank wants Neal to put his skills to work finding Allie Chase, the rebellious teenage daughter of a prominent senator. The problem: Allie has gone underground in London, and to get her back, Neal has to follow her into the punk scene, a violent netherworld where drugs run rampant and rage is the name of the game. Up against punk junkies, antique book thieves, and murderous betrayal, Neal has his work cut out for him to save Allie … and get back above ground for good.
