I was 10, and I played Jim Hawkins in 'Treasure Island' at school, and this great Liverpudlian actor called Andrew Schofield - he was Johnny Rotten in 'Sid And Nancy' - came to watch it, and he had a word with my mum and dad afterwards and told them I should have a go at the Everyman youth theatre. I've never looked back.

Mysteries include so many things: the noir novel, espionage novel, private eye novels, thrillers, police procedurals. But the pure detective story is where there's a detective and a criminal who's committed a murder and leaves clues for the detective and the careful reader to find.
