'This book... shines a bright light on a murky world. The contributors attempt to understand the origins of murder, but they also deal with the detail of treatment and show us how professionals are affected by powerful psychological forces. The impartial detachment of the observer/supervisor is an artificial construct, and once we realise that, we will be in a better position to do the job properly. The approach is psychodynamic, but there is plenty here to stimulate non-believers. In fact, the book is a challenge to the world of cognitive behavioural therapy; there is more to murder than relapse prevention. It made me think, and what more can you ask?' - Professor Tony Maden, from the Foreword.
