HEADLINE'S LATEST AMAZING THRILLER ACQUISITION: New York Times bestseller Lisa Gardner's backlist moves to Headline with the sixth book in the FBI Profiler series, SAY GOODBYE.

Sunday Times and New York Times bestseller Lisa Gardner returns with SAY GOODBYE, the sixth book in the FBI Profiler series. AS A TWISTED KILLER WEAVES HIS WEB CAN YOU STAY FREE? The Daily Mirror says this is 'suspense of the highest order'. Karin Slaughter and Tess Gerritsen love Lisa Gardner. Have you read her yet?

Women are going missing; prostitutes, runaways, the forgotten ones. Eighteen-year-old Delilah Rose knows something about their disappearances but she'll only talk to one woman, FBI Special Agent Kimberly Quincy.

Even as Kimberly struggles to comprehend the horrifying tale Delilah has to tell, she must trace their only lead - a man who gets his kicks in the creepiest of ways - if she is to find a brutal serial killer, who is surely about to strike again.

With no bodies and no clues, Kimberly's options are limited. Yet she feels herself drawing ever closer to the culprit. But how close is too close? And when is it time to say goodbye?
