I adore this programme...my daughter and I spend ages trying to work out who the Balaclava Man is.We watch all these type of series and are getting quite "expert" at it.
While Roz appears to be corrupt,I think she is trying to prove herself,after having been off the scene for a while,so is desperate for them not to find her DNA at Tim`s flat.
Her husband has not helped by being seen near the flat although only there thinking that Roz is having an affair.
Oh my goodness..what a confusion..cannot wait til next Sunday!!!!!
