We're almost at the end of the series and we still haven't figured out who that was with the belt and the knife in episode 1 (Well, we think we have but we're keeping mum until we're sure). Anyway, tonight the girlos are heading off to a care home to investigate complaints made by the daughter of a man who died there. Meanwhile Dorothy's worried that Rachel is a bit of a bad influence, while Janet gets her head bitten off by Gill for her, err, inappropriate behaviour toward young Rob. Never a dull moment...
