The investigation into a serious motorway accident in Oxfordshire reveals much more than the police bargain for.

A woman’s body is found in a clapped out campervan. Her wounds indicate she died elsewhere. The other occupants have long since fled the scene.

DI Tanya Miller leads the man-hunt. But the fugitives, two men from a wealthy Birmingham family, continue to escape their grasp.

When the post-mortem reveals an unlawful killing, and strange bite marks on the woman’s skin, the attempt to find the men becomes a priority.

The men themselves will stop at nothing to prevent being caught. But what exactly are they escaping from? And if DI Miller catches them, will the case be solved?
