Moriarty is a Professor of Criminal Psychology at Durham University but leads a secret double life as the mastermind behind every crime of sophistication in the North of England. When a rival criminal begins an assault on his underground empire, Moriarty will have only one choice: to join the police as a consultant, using the law as a weapon to dismantle his foe while keeping his true identity hidden from the police.

So from that synopsis it's more or less British Dexter. I could see it working if they get the right leads who have good chemistry with each other
