S4·E1 Someone You Know

Jane has a new boyfriend whose passion is glider flying - something Jane is rather nervous about. However, she is called away to work on the case of a serial killer who murders women having affairs. The killer leaves a message scrawled in blood on a mirror, ""Help me, Jane."" The police think he must be one of Jane's patients, but Jane is not so sure. To complicate matters, Jane's boyfriend is an ex-patient and tries to pressurise Jane into deleting his file from her computer. One of the female detectives is having trouble with this case. Jane recognises her symptoms and tries to help, but something buried deep in her past has been re-awakened. Investigating further, Jane discovers that her mother is also called Jane. Jane discovers that the police have been following her and when one of her more vunerable patients ends up in hospital as a result, she finds herself pressurised from all sides to uncover the killer.
