On the 22nd October 2014 Darren Sykes lures his sons Jack and Paul into the attic with the promise of a new train set. He then sets fire to the house, leaving the children, and himself, no way of escaping. Jack and Paul’s mother Claire Throssell reveals the years of torment she and the boys suffered at the hands of Darren, how his behaviour spiralled out of control and the devastating impact of his actions. She also reveals how her oldest son Jack told fire fighters: My dad did this, and he did it deliberately. Our experts, psychologist Emma Kenny and former Detective Superintendent David Swindle, look into how a father could commit such an act and the impact it has had on Claire’s life. Claire also reveals how her local community have helped rebuild the house and how her campaigning work has helped her.
