A post mortem examination shows that Donald Griffith died from a blow to the neck, and not by drowning, supporting DCI James's theory that one or other of the women in his life had decided to profit from his death.

Blackton's investigation gets closer to the truth.

Detective Chief Constable Blackton begins an investigation into both the Cripps shooting and the investigation into James Lampton, which drags up problems for both Commander Blake and D.C.I. Hedges.
