Tanya has left to live with Barbara and John and expresses her feelings of guilt to John. She tells him that she didn't want to visit Vic because his room smelt. Tanya feels that Leanne's disappearance would've never happened if she'd joined them. John tries to reassure her. Eventually Tanya goes to stay with her dad in France. The police have a lead that Leanne may have started seeing her ex- husband, but they haven't followed it up. DCI Iain Barclay (Hugh Bonneville) is obsessed with following the flower seller, a Bosnian, who may have links with illegal immigration from Macedonia. This frustrates the rest of the team.
