Exercise in Terror

This taut thriller from the Edgar Award–winning author of When the Dark Man Calls “builds with great tension to a shocking conclusion” (Chicago Tribune).
 
On a hot summer afternoon, Maureen sits with her two children in the family car, anxiously waiting for her husband David. There are two men lurking nearby—a couple of drunks who followed them here from the supermarket—and they make Maureen nervous. As David is walking back to the car, the drunks take a baseball bat to his skull. Maureen can do nothing but try to shield their little boy and girl as their father is murdered before their eyes.
 
Eight years later, Maureen makes a living as an exercise instructor and all-around fitness freak, a rigorously disciplined lifestyle that has helped her family get past the horror of David’s murder. But one day, the killers call to taunt her, and say they are not finished tormenting her family. They are coming for Maureen, and no matter how fast she runs, she cannot escape . . .
