Lies of Silence is the 1587th episode of The Bill.
On temporary assignment to the Serious Crime Group, DC Lennox is surprised to find Liz Rawton is Acting DI at SCG. The body of a young girl, later identified as Hayley Spence, is found in a concrete slab in a cement works. Rawton and Lennox question the new owner of the cement works, Digby Leake, and Rawton tells Lennox off for his aggressive approach to the case. Hayley's ex-boyfriend tells them of a modelling agency which doubled as an escort service where Hayley worked and that Hayley was pregnant, and the owner Leon Walsh is certainly suspiscious, especially when the police find a car of his containing Hayley's blood. When forensics reveal that Hayley died of an ectopic pregnancy, and was not murdered, Leake admits that he was the father and that his assistant Harry Rawlings dumped the body when Hayley died from the complications. Lennox forms a bond with Hayley's friend Karen, who confides to him that Rawlings and Leon are involved in smuggling heroin from Hong Kong, and the pair are arrested. Rawton congratulates Lennox on solving the case and offers him a job at SCG, but he declines, preferring to remain at Sun Hill.
