1. The 12 Apostles

The story of Lesley Howell and Trevor Buchanan. In 1991 they were murdered by their spouses who then staged a scene to make it look like they had taken their own lives. 18 years later - one of the killers decided to confess.

Episode 1 - The 12 Apostles

When the bodies of Trevor Buchanan and Lesley Howell are found in a garage in the quiet coastal village of Castlerock, Northern Ireland - police believe it is a suicide pact.

While witness statements show their partners lied to police and there are a number of red flags at the scene - a coroner’s inquest raises no further concerns about their deaths.
