The location: a picturesque seaside town in 1991. The scene: two bodies in a carbon monoxide filled car. Nurse, Lesley Howell, and police officer, Trevor Buchanan, have apparently taken their own lives...This is the true story of a Sunday school teacher and respectable dentist and pillar of the community, who formed a murderous partnership. Hazel Buchanan and Colin Howell met at their local Baptist Church in Coleraine, Northern Ireland and embarked upon a passionate and destructive affair, which climaxed in an elaborate plot to commit the "perfect murder".
