Tattie meets a vulnerable girl

Tattie is losing patience as she tries to help Big Bob lose weight, particularly when Molly and Christina tell her to leave him alone. Tattie then turns her attention to a young girl name Silvie, who she saw begging earlier in the day. Silvie is complaining of stomach pains, and when Tattie takes her blood pressure, she notices marks on Silvie's arms. Tattie is concerned as to how she got them, but Silvie isn't keen to open up and takes the first opportunity to leave the surgery with Tattie's purse in hand.

Later, Tattie finds that Silvie has left her phone and has received numerous threatening messages from someone called Sean. Tattie decides that she needs to let Will know - and goes to find Robbie to get a message to him.

Meanwhile, Will is working on his first murder investigation - a young prostitute who has been killed in the area. Despite feeling physically sick at seeing the body, Will wants to impress DCI Donald with his professional attitude - and that also means ignoring Robbie's numerous phone calls. Will hunts and hunts on the CCTV images to get some clue as to what happened to the girl, not realising that Robbie might unintentionally have some crucial information.

Elsewhere, Eileen wants to go to a singles' night with Gina - but Gina is less than keen. When she finds out that Murray is going out with Raymond, however, she decides that maybe it's time to move on. Later, when Eileen and Gina spot Murray and Raymond crash and burn with ladies in the Tall Ship, they realise neither of them are quite ready to face dating.
