The Watcher in the Wall

A heart-pounding new Stevens and Windermere thriller from the award-winning author of The Stolen Ones and The Professionals.
 
Kirk Stevens and Carla Windermere of the joint BCA-FBI violent crime task force have handled shocking cases before, but this one is different. Stevens’s daughter, Andrea, is distraught over a classmate’s suicide, but what the two investigators find is even more disturbing—an online suicide club of unhappy teenagers, presided over by an anonymous presence who seems to be spurring them on. Soon, it becomes apparent that the classmate wasn’t the first victim—and won’t be the last, either, unless they can hunt down this psychopath once and for all.
