For better and worse, a work environment represents a microcosm of society. While lifelong friendships are formed at a job, and perhaps it's a place where people even meet their future spouses, working alongside others also increases the likelihood that creeps may be close by. The Killer Beside Me exposes the dark underbelly of workplace evil where rivalry, romance, and the abuse of power culminate in a brutal slaying. Each episode in this series retells the shocking events leading to a horrific murder. How well do we really know our co-workers?
