Worse than Dead — Stephen Puleston

A ferry leaves Dublin...The chief engineer lies dead on the car deck ...There's a killer on board...
Inspector Drake is called from a seminar on cyber crime to meet the ferry docking at the port of Holyhead. Frank Rosen the chief engineer lies on the car deck a knife through his heart. For the first time Drake knows where the killer is but he doesn't know who.
When Rosen's house is ransacked the night after he's killed Drake knows the killer was looking for something. The data stick Rosen's wife finds may hold the clues. But the codes and numbers on it only complicate the investigation.
And then Drake's cousin makes contact and tells him he has information. But can Drake rely on him or does he have another agenda? And when the team discover a direct link to drug dealing in North Wales and beyond there are powerful forces at work.
Drake's cousin drags Drake's family into the middle of the case that piles the pressure on Drake who's facing regular counselling for his OCD and the prospect of losing his father to cancer.
When Drake's superior demotes him and acts entirely against protocols Drake knows that something is wrong. Establishing the evidence takes him to Dublin and Cardiff and then on a last minute chase over North Wales to the ancient Fort Belan hoping that he will catch the killer.
