The Essex Millionaire Murders

The concluding part of a two-part documentary series. Detectives raid Luke D'Wit's home and seize a huge stash of prescription drugs - including fentanyl and antihistamine - that are both found in the Baxters' postmortem as police press Luke to explain his relationship to Carol Baxter's mysterious American physician Dr Andrea Bowden. Luke has been mixing 'medicinal' drinks for Carol on Dr Bowden's instructions, but detectives can find no trace of her existence - meanwhile, Ellena Baxter is completely cleared of her parents' murders and agrees to be interviewed as a witness for the police. As Ellena slowly realises that Luke has been a cuckoo in the family nest, detectives spend months combing through D'Wit's multiple digital devices to piece together the scale of his deception and cruelty.
