‘She vanished at the same time as Abigail,’ Jasmine says so matter-of-factly that I think I’ve misheard. ‘Vanished?’ ‘Three days after the girls didn’t return from choir practice, my daughter was found by the side of the road with head injuries, a broken leg and pelvis. Hit and run, the police reckoned. She’d also suffered an extensive bleed to the brain, and when she came out of her coma, she was as you see her now. And she was never able to tell us what happened to her and Abi or how she ended up where she was found. Everything she knows is locked inside her head.’
