And then there's the monumental task of providing concert security for rock legend Rogan O'Neill . . . But for Detective Inspector Colin Anderson, the nightmare is about to get terrifyingly close to home. For a third boy has now gone missing - Colin's own son, Peter. The team race to find the boys before it is too late. But how long will it be before they realize the key is hidden in the lyrics of a rock song ? 'Tambourine Girl' by Rogan O'Neill?
