7. Fault Lines

Complete story — includes the ending

Ronnie and Sam investigate when crime scene examiner Kelly Mahon is found stabbed to death in her flat. All the lines of inquiry begin to lead to a dead end, until her colleague, Lucy Kennard, makes a claim that she was attacked outside her flat by an angered cabbie. The cabbie is soon found to have a connection to Kelly, and after forensic evidence places Kelly's blood on his trainers, Ronnie believes they have the right man. However, as things seem to appear cut and dried, Sam finds himself entangled in a sexual relationship with Lucy. Whilst investigating the contents of Kelly's stolen handbag, they discover that at the time of the stabbing, she was in possession of an Ann Summers gift card worth £100. Sam soon discovers that the card had been activated once in the last month to buy a size 10 red nightie, however, no trace of a nightie is found at Kelly's flat. As their relationship grows deeper, Sam is startled and horrified to discover the nightie in Lucy's bathroom. Jake and Alesha soon discover that Lucy may well have been Kelly's killer – and that the forensic evidence found on the cabbie may have been placed there by Kelly's friends to deliberately implicate him. And as a string of men who have had money extorted from them by Lucy come to light, Jake and Alesha believe they have enough evidence to prosecute. However, with Sam's sexual involvement hanging over their shoulders, the case threatens to collapse after Lucy accuses the judge of the trial of bribing her with release in return for sexual activities.
