We love telly: PICK OF THE DAY - Body of evidence - WIRE IN THE BLOOD UTV, 9pm.
ARGUABLY the most brilliant bit of detective work in the second part of this grisly thriller comes from the colleague of a teacher who has gone missing.
She thinks the woman might have been nipping out at lunch for sessions with a secret boyfriend she never talked about.
"So how did you find out?" asks Dr Tony Hill (Robson Green), quick as a flash. "She came back once with her dress on inside out. Bit of a giveaway."
Oddly, none of the real detectives have spotted that their own colleague Chris has also been looking a bit rumpled in the afternoons.
But how long can he keep it a secret that he was the missing teacher's bit of rough?
It's not the only outrageous coincidence this week either.
As Hill's forensic psychologist so brilliantly deduced last week, the police should be looking for a serial-killing sadist who keeps his victims alive while he marinates them internally in a blend of herbs and spices before slicing them up for snacks.
In other words, the man - or woman - they're seeking is an amputee-obsessed gourmet cannibal, which ought to narrow things down considerably. How many of those can there be stalking the streets of Bradfield?
Actually, you'd be surprised. And as Chris receives a body part in the post, his problems are just beginning. That teacher girlfriend of his isn't the only one who reckons he looks a bit tasty.
If you thought last week's appetiser was a stomach churner, the main course is even worse.
HILLSIDE Dr Hill (Green) and DI Fielding (Simone Lahbib)
