Dr Kate Hanson and the Unsolved Crime Unit are facing their most challenging cold case yet: the year-old murder of a female student. When, a year after she went missing, the body of 19-year-old student Elizabeth Williams is discovered in a field near her college, Dr Kate Hanson and her colleagues are faced with a seemingly impossible challenge.

To do that, she must look beyond what she and her colleagues are being told by those who knew Elizabeth – and into the twisted psyche of a dangerous murderer: a killer whom Kate suspects is ready to kill again.
