Three days before he was due to sit India's rescheduled medical entrance examination, 17-year-old Kahaan Patel jumped from the sixth floor of his family's apartment building in the western city of Ahmedabad. When his family entered his bedroom after his death in the early hours of 18 June, it looked as though he might return at any moment. On the shelves were Harry Potter novels, a book on Elon Musk, a collection of Goosebumps horror novels and board games. "The only thing missing," his father, Prashant Patel, says quietly, "was Kahaan." For Prashant Patel, the story begins not with his son's death but with a dream.
