Last Seen Wearing

Last Seen Wearing is the second Inspector Morse novel in Colin Dexter's Oxford-set detective series.
Why now? Why Friday 12th September – two years, three months and two days after Valerie Taylor had left home to return to afternoon school?
He frowned. 'Something's turned up, I suppose.'
Strange nodded. 'Yes.'
After leaving her home in Oxford to return to school in London, seventeen-year-old Valerie Taylor completely vanished. Despite the efforts of the police and Chief Inspector Ainley, the trail went cold and she was never found.
Two years on, Ainley is dead, and Inspector Morse is handed the case. But now, someone has decided to supply some surprising new evidence . . .
Last Seen Wearing is followed by the third Inspector Morse book, The Silent World of Nicholas Quinn.
