Joanne was a solicitor who Peter Barlow consulted when he fell under suspicion of pushing his father Ken down the stairs of 1 Coronation Street, largely on the evidence of Chloe Tipton, a psychotic stalker whose attentions Peter had spurned when he met her as a cab driver for Street Cars.
Pushed by Joanne into providing more details as to why Chloe was lying, Peter admitted that he had gone to Chloe's house several times, attracted by the large tips she gave him. Being frank, Joanne said there was little to substantiate Peter's claim that he did little to attract Chloe and he was forced to admit that he also comforted the woman at the time as she said she was going through some personal problems and they had kissed for a few seconds, though she had initiated the action and he had pushed her away. Peter's girlfriend, Toyah Battersby, who sat in on the consultation, hadn't known this specific part of the story and the revelation caused a rift between the two.
