Susan Edwards, whose case inspired the TV drama Landscapers starring Olivia Colman, is seeking a fresh appeal against her 2014 conviction for murdering her elderly parents. Edwards, now 67, shot William and Patricia Wycherley in May 1998 with the help of her husband Christopher, then buried them in the garden of their Mansfield, Nottinghamshire home and maintained the pretence they were alive for 15 years while siphoning their money to fund an extensive Hollywood memorabilia collection. Her solicitor has said the legal team is "seriously considering" submitting grounds of appeal to the Criminal Cases Review Commission in light of "newly obtained information", reviving public interest in a case notable for its bizarre and elaborate deception.

The couple, given life sentences with a 25-year minimum term, diverted more than £245,000 (later revised to over £286,000) from the Wycherleys' accounts, pensions and the sale of their house, while forging letters and Christmas cards to convince family, friends and officials the pair had simply moved away. Susan Edwards has always denied primary responsibility, claiming her mother shot her father and provoked her into shooting her mother, though a judge ruled Christopher Edwards fired the fatal shots with a Second World War revolver. The deaths only came to light when inquiries were made about William's upcoming 100th birthday, ending a cover-up so convincing that neighbours believed the couple had emigrated or gone on holiday.
