David Hunter and his wife are found dead in a small Yorkshire village. The apparent victims of a hit and run. They led successful and quiet lives, so police are stumped when looking for a motive.

DI Stewart Gardener and DS Sean Reilly have their work cut out and soon some suspects emerge: a group of four closely connected individuals who are proving hard to trace.

Convinced this was not a random killing, the Leeds detectives venture into unknown terrain, the web of lies, fake identities and cyber crime called the internet.

But when one of the suspects in the investigation is identified and found, the police are dismayed someone else got to them first. Dying from a nerve agent, he won't be much help to the investigation.

The race is on to catch up with all the persons of interest. But dealing with skilled hackers who know how to move without leaving a trace, will stack the odds against the detectives.
