A woman wakes up at her home having sleepwalked, and done things she doesn't remember, one day she wakes up with a bloodied hammer under her duvet, believing she's killed her partner, whom she thinks is having an affair.
I would say this is a decent episode, it's not made, nicely acted, but somehow it lacks a bit of sparkle. Back to the serious tone after Neighbours, but it lacks the humour, tension and excitement.
Keeley Hawes is good, but somehow she's wasted, in a part that doesn't exactly challenge someone of her talent.
The main trouble here is that the story and outcome are glaringly obvious after just a few minutes. Still it's a decent watch, but doesn't have the edge of other episodes. 6/10.
