Death in Paradise BBC1, 9pm
A fashion show takes a chilling turn when young model Zoe Mackay is strangled just moments after leaving the catwalk, and while the crew and other models come under suspicion, they all have watertight alibis. To make matters worse, there are no witnesses or DNA evidence, the only clue being a single stocking clasped in the victim's hand. What does it mean – and how was her killer able to strike without being spotted? Meanwhile, JP recognises one of the models as a school crush on at school. But will she remember him?
