A woman called Gemma comes to Alison, asking for her help, after her best friend was killed by a ghost. Alison is sure Gemma knows more about the spirit than she is letting on. But Alison has other things to worry about - her mother's spirit is still around and still cleaning. In the mean time, Robert comes clean to Jude about his tumour.
