When Janet and Paul Bett's daughter held an eighteenth birthday party in their lounge, the worst they expected was teenage drinking. The reality couldn't have been more different. Half an hour after a slow dance with her father, Leah Betts collapsed. She had taken an Ecstasy tablet.
Leah's death made headline news, the result of Janet and Paul's decision to release a photograph of her as she lay in hospital attached to a life-support machine.
