In Kingston upon Hull, innocent victims are terrorised in their own home by a knife-wielding intruder. Humberside Police must identify and track this dangerous suspect and bring him to justice.

As the investigation gains momentum, there is an unbelievable turn of events - less than 24 hours later, the same victims are targeted again, but this time by two attackers, and left traumatised. Detective Constable Heather Butler must build a strong case to put these hardened criminals behind bars once and for all.

During an in-depth investigation, incriminating evidence is found, including a razor-sharp meat cleaver left behind at the crime scene. But as the case unfolds the connection between the two attackers stuns detectives.

Time is of the essence for Humberside Detectives. As the suspects finally face detectives in the interview room, will damning evidence allow police to play them off against one another? And will this result in an imminent confession?
