Newly widowed Detective Chief Inspector James Hardy's investigation is one that will have long lasting repercussions. The body of a young woman is pulled from the River Thames and Hardy discovers the victim is known to him.

It's soon apparent the victim's flatmate is on the run for her life and she could be the key to revealing the identity of the killer. In a race against time, Hardy must track her down before the killer does.

As the truth behind the investigation unfolds, Hardy's own family come under threat. With two young daughters to protect and an investigation that twists and turns, Hardy finds himself pushed to the brink.

With his every move scrutinised by the press, a witness on the run, and a killer growing in confidence, how will Hardy handle the pressure and solve the investigation?
