Suicide

25 years after her son commited suicide as a result of school bullying, Jill Craig decides to take revenge on the bully, Scott Martin. She employs the former bully's services for odd-jobs and pretends to befriend him over a period of many months while all the time setting him up for a murder. She shows him her jewellery in order to have his fingerprints on it then plants some of it in his shed, she even secretly changes her will in his favour to give him a motive. She then kills herself in such a way as to make it seem as though Scott Martin had murdered her and tried to make it look like suicide so he could inherit her money. With her carefully engineered forensic evidence stacked against him he receives a life sentence for her "murder".
