Midsummer, and in an unassuming house on a quiet residential street on the edge of Brockwell Park in south London, a husband and wife are discovered, imprisoned in their own home. Badly dehydrated, they've been bound and beaten, and the husband is close to death. But worse is to come: their young son is missing. When Dl Jack Caffery of the Met's AMIT squad is called in to investigate, the similarities to events in his own past make it impossible for him to view this new crime with the necessary detachment. And as Jack digs deeper, as he attempts to hold his own life together in the face of ever more disturbing revelations about both the past and the present, the real nightmare begins… Horrifying, unforgettable, intense, The Treatment is a novel that touches the raw nerve of our darkest imaginings.

The finale is an extreme emotional catharsis, involving both redemption and terrible irony' – Guardian "Mercilessly realistic… The Treatment is exactly what the crime genre needs: a book that treats cruelty with a new moral seriousness' – Metro
