S3·E2 Tinker, Tailor

When a man, Charles Fitzroy, knocks on the door one evening asking for some water for his car, Sharon tells him all about Dorien and her relationships, which he seems interested in. After visiting Chris in prison, Sharon suspects that Charles may have been a police spy interested in the proceeds of Darryl and Chris' crimes. Soon after two policemen come round and they ask about the whereabouts of Dorien and Marcus, who needs to be questioned about a major fraud case of which he was the accountant. Sharon tells them they are on holiday in Zurich. When Dorien returns she finds that a Sunday newspaper has an article on her private life, and Sharon and Tracey feel guilty.
