An intrepid medic tracks a killer looking for the ultimate thrill.

Police doctor Callie Hughes is having doubts about her life on the south coast after her boyfriend's move to Belfast, when a mysterious death draws her once again into a criminal investigation.

A woman is found dead in a holiday let. There are no signs of sexual assault but her bruised neck and protruding tongue suggest foul play. Callie notes a small mark on the woman's partly exposed breast.

The once supportive DI Steve Miller has a new love interest and without him being on the ball, the case seems to be going nowhere. Well, that's until another body is found some days later. Going downhill would be more accurate.

Suspicious that someone is targeting visitors to Hastings, the medic decides to carry out her own inquiry with the help of Miller's increasingly frustrated partner, DS Bob Jeffries.

But without a safety net, and faced with a killer who knows how to cover their tracks, Callie is the only person standing between them and freedom. And that makes her the number one target.
