When Robin Oake's son, Special Branch officer Stephen, was killed by a terrorist while on duty, a press conference was called.

A journalist asked, 'Mr Oake, what do you think about the man who killed your son?' and received a startling reply: 'I don't know the man or the circumstances but from my heart I forgive him.'

Another journalist said, ' What?!' and our response may well be the same.

But in this powerful and moving book, Robin shares his story and the reasons for his amazing forgiveness.

Using examples from his long experience in the police he explores the 'why' and 'how' of forgiveness - even in extreme circumstances.
