As a teenager, Audrey Harte went to jail for murder. Now, she uses her own experiences to help catch dangerous killers. Richard le Duke is the most ruthless serial killer criminal psychologist Audrey Harte has ever encountered. When Richard's son—and suspected accomplice—is arrested, police hope they have leverage over Richard to get him to release his latest victim. Instead, they find themselves up against a mind almost as warped as his father's. Matthew le Duke will give up his father's location on one condition: Audrey tell him every gruesome detail of her own dark past. If he doesn't contact his father within the hour, a young woman will die, and her murderer will escape. All Audrey has to do is finally reveal what happened that night—and how it felt to make her first kill. Audrey Harte novels It Takes One Two Can Play Three Strikes Four of a Kind
