The watcher in the wall : a Stevens and Windermere novel

Summary: Stevens and Windermere, Book 5, following STOLEN ONES. Kirk Stevens and Carla Windermere have handled shocking cases before, but this one is different. Stevens's daughter 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. Canadian author - Vancouver.
