On the evening of May 4th, 1998, a Vatican nun heard strange noises coming from the apartment of her neighbors - Swiss guard commander Alois Estermann and his wife, Gladys. When she went to investigate, she was shocked to find their bodies, along with the body of young guardsman Cedric Tornay. A secretive Vatican investigation concluded Cedric shot the couple and himself in a fit of madness. But was there more to the story - a love triangle, freemasons, Opus Dei, Stasi - being covered up?
