I, Alex Cross

Detective Alex Cross is pulled out of a family celebration and given the awful news that a beloved niece was brutally murdered. Alex vows to hunt down the killer, and soon learns that she was mixed up in one of Washington, D. C.'s wildest scenes. And she was not this killer's only victim.
The hunt for the murderer leads Alex and his girlfriend, Detective Brianna Stone, to Washington's most infamous club-a place where every fantasy is possible, if you have the credentials to get in. The killer could be one of their patrons, one of Washington's elite who will do anything to keep their secrets buried.
