May 1991: In the seaside town of Castlerock in Northern Ireland & the bodies of two people
- police officer Trevor Buchanan & nurse Lesley Howell
- are found in a car filled with carbon monoxide. Their spouses were having an affair & apparently the pair are so distraught they have taken their own lives. Their adulterous spouses
- Sunday school teacher Hazel Buchanan & dentist Colin Howell
- had met in the local Baptist Church. Following the apparent double-suicide they continued their affair secretly for some time but both later remarried. A series of disasters in Howells life
- the death of his eldest son substantial losses in an investment scam & the revelation that he had been sexually assaulting sedated female patients
- led to him declaring that he was a fraud a godless man & telling the elders of his church that he & Hazel Stewart had conspired together to murder their spouses nearly two decades earlier. That confession led to two of the most sensational murder trials ever seen in the United Kingdom Howells conviction for murder in December 2010 & Stewarts in March 2011 despite her protestations of innocence. Distinguished journalist Deric Henderson has been all over this story since it broke. Now for Let This Be Our Secret" he has carried out extensive interviews with close relatives friends & associates of Colin & Lesley Howell & Trevor Buchanan & Hazel Stewart. He has examined the 1991 police investigation that failed to detect a crime. & he has also explored how the affair embarrassed & then scandalised the Baptist Church. In " Let This Be Our Secret" Henderson has produced the definitive account of one of the most extraordinary murder cases to hit these islands for decades."
