Split Second

by Catherine Coulter

Published 1 July 2011
#1 New York Times bestselling author Catherine Coulter returns with another pulse-pounding thriller featuring FBI agents Dillon Savich and Lacey Sherlock... 

A serial killer is on the loose, and it's up to FBI agents Dillon Savich and Lacey Sherlock to bring him down. They soon discover that the killer has blood ties to an infamous and now long-dead monster. Savich and Sherlock are joined by agents Lucy Carlyle and Cooper McKnight, and the chase is on. 

At the same time, Agent Carlyle learns from her dying father that her grandfather didn't simply walk away from his family twenty-two years ago: he was, in fact, murdered by his wife, Lucy's grandmother. Determined to find the truth, Lucy moves into her grandmother's Chevy Chase mansion. What she finds, however, is a nightmare. Not only does she discover the truth of what happened all those years ago, but she faces a new mystery, one that has been passed down from mother to daughter for generations.

As the hunt for the serial killer escalates, Savich realizes he's become the killer's focus, and perhaps the next victim. It's up to Lucy to stop this madness before it's too late.

FBI Special Agent Griffin Hammersmith has been recruited by Dillon Savich to join his unit in Washington, D.C. Savich sees something special in Hammersmith, an almost preternatural instinct for tracking criminals. While on his way to D.C., Hammersmith plans to visit his sister, Delsey, a student at Stanislaus School of Music in Maestro, Virginia. Before he arrives, he gets a phone call that Delsey was found naked, unconscious, and covered with blood after a wild party. The blood isn't hers -- so who does it belong to? Meanwhile, back in D.C., Savich and Sherlock have their hands full when the grandson of former chairman of the Federal Reserve Bank is found murdered, every bone in his body broken, and frozen at the foot of the Lincoln Memorial. Was Savich right -- is Griffin gifted with a unique ability to "see" how criminals think? And will he figure out who was behind the attempt on Delsey's life -- before it's too late?
