A breath of sky broke through the canopy of trees in the small clearing. A wooden cross had been pushed into the earth, and four candles surrounded the boy. He looked as if he was sleeping, but the rotting leaves upon which he lay were his grave.

In the early hours, Head of the Ritualistic Behavioural Crime unit, Dr Harrison Lane, is called to a woodland to find the lifeless body of a young boy. Scrawled across his chest is a Latin satanic exorcism prayer and scraps of paper covered in quotes from the Old Testament are stuffed in his mouth. Who would want this innocent child dead?

Harrison is certain the killer has links with a religious group, and the clue lies in the twisted individual’s childhood.

As he delves further, Harrison visits a cemetery and realises he’s been there before, dredging up a chilling memory from his past. When he was a little boy, his mother, dressed in a black cloak, had brought him there just before she died.

While Harrison tries to make sense of his traumatic flashback and how it might be linked to the case, a child goes missing while on his way to a leisure centre on a busy Saturday morning.

Can Harrison battle the demons of his own past and find the killer before the life of another innocent child is taken?
