She's also a hairdresser who'd give Sweeney Todd nightmares - in her beauty salon, one customer is smothered to death by cling film while having a body wrap, and another is driven to suicide after a trademark Jill cut.

Deep down though, Jill just wants to be loved. But unfortunately not by her own husband Terry, whose diagnosis with inoperable cancer at the beginning of the first series is just the fresh start Jill needs.

Of course, all good murderers need accomplices, and that's where Linda and Glen come in. Linda is Jill’s assistant at her salon, and is always at Jill’s beck-and-call – largely because Linda’s terrified of her. But for a long time, behind that facade of puppydog devotion, Linda was hiding a terrible secret from Jill - it was she who had sex with Terry while Jill was in Bristol watching Phantom on Ice. And when Jill found out, she very nearly killed her.

He was very taken with Jill, but she wasn't interested. However when he told her about his inheritance, she realised she did love him after all, and moved in with him. His blind devotion to Jill (plus his desperate desire for the intercourse) led him to poisoning the Vicar, confessing to murder and then poisoning himself. And after all that, he never even got the intercourse.

 Jill, of course, followed them and resumed her quest to drive a wedge between Cath and Don, culminating in a furious Cath throwing her wheelchair off a cliff while fighting with Jill, only for it to land on Don's head. Jill got her man in the end – severely brain-damaged, but hey, she got him.
