I was looking forward to this and tolerated a few episodes in the hope it would get better. I like Sheridan Smith but why is she continually smirking regardless of what emotion she is supposed to be having? I feel like she's mailed this performance in. The writing is dire and story line totally unbelievable. We are supposed to believe that she works all night, gets home gets the girls up who have been alone all night, feeds them and gets them to school then goes to another job? When does the poor woman sleep and why is she never tired? I won't go into her getting a stranger (guy) in to board with her two girls while she is away at work. Just put the nail in, there is no way cleaners have time to skulk around and plant recorders and then listen in. They work as a team doing the job as fast as possible and in a team. Two of them going missing would be noticed and they'd be sacked. So that's rubbish too. It's a shame really. Was a good story line, just handled incompetently. A bit of research and forethought may have elicited a higher score than 2 from me.
