Accident? Dangerous game gone wrong? Or murder? DI Blackwell faces her toughest case yet.

When the body of a young woman is discovered in a shipping container in Bristol, the police suspect she was an illegal immigrant whose death was a tragic accident. But their theory is shot down by two pieces of evidence: the container was due to ship out, not in; and, even more sinister, a video camera with a live feed was filming her from a hidden compartment.

Someone watched her die. Slowly.

DI Louise Blackwell is ten weeks pregnant, a fact she has largely kept to herself, and between bouts of morning sickness she now has a murder to investigate. While the docks offer few other clues, the discovery of more live feeds convinces Blackwell that there are other trapped women...and that some of them are still alive.

As she scours historic missing-persons cases looking for a pattern to the abductions, Blackwell finds herself in a race against time to uncover the voyeuristic killer's motive and stop any more women becoming caught in the cruel and deadly game. But with every step being closely monitored, can she outwit a murderer whose method means staying hidden?
