DCI Sutton is once again tasked with a high profile case, this time it's a rapist and sex attacker who focuses on elderly victims.
Sutton is clearly a hugely competent Detective, only this time he's treading on someone else's toes, he's trying to muscle in on the case for want of a better phrase.
It's a powerful opening episode I thought, it really is the stuff of nightmares. Outrageous crimes, hideous, worse still, how long he got away with things.
Clunes is terrific once again, he plays the part with conviction, some real subtlety, he never tried to overdo things.
Stephen Wight, who plays Clive, was going to be seen by millions, appearing here, and over on BBC 1 in Silent Witness, same night, same time.
It's very chilling, all in all, a cracking start, 9/10.
