It is the middle of the night ...The road is deserted ...A killer is waiting ...

Two traffic officers are killed on an isolated mountain pass in North Wales. Inspector Drake is called to the scene and quickly discovers a message left by the killer - traffic cones in the shape of a No 4.

The killer starts sending the Wales Police Service lyrics from famous rock songs. Are they messages or is there some hidden meaning in them?

Does it all mean more killings are likely? When a politician is killed Drake has his answer. And then the killer sends more song lyrics. Now Drake has to face the possibility of more deaths but with numbers dominating the case Drake has to face his own rituals and obsessions.

Finally when the killer threatens Drake and his family he faces his greatest challenge in finding the killer before he strikes again.

The body of a young Pole working in Cardiff is pulled from the River Taff. His tongue has been amputated in some sort of ritual.



More murders in the Polish community take Inspector John Marco and his team into the East European immigrant community and the murky world of people trafficking.



But what is it that links all the deaths together?



When the evidence points to one of the city�s criminal and the involvement of a gangster from Poland Marco faces the challenge of gathering evidence from a close knit and secretive community.
And why do the Polish Secret Service seem to be interested?
When Marco finds himself entangled emotionally its impossible for him to think clearly. In search of an answer Marco travels to Poland only to find himself implicated in a murder and hoping he can avoid another.




Racing back to Cardiff he hopes he has enough to unravel the case and arrest the perpetrators.
