In the early hours of the morning DI Mark Tartaglia is sent to a London hotel to investigate the murder of a young woman. When he recognises the victim, the case takes a dark and personal turn.

Another case he has been investigating-the body of a homeless man found in a burnt out car-is also not what it seems. Tests reveal that the body has been assembled from the parts of four different people.

Tartaglia now has a far more macabre puzzle to solve. With the clock ticking, and torn between the two investigations, he must decide where his priorities lie.
