 A dead man who was lying there. Good gracious me. Yes, he had a great gash in his throat and the whole place was swimming in blood. But who was this murdered man? You've made inquiries, Lestrade. Of course. There's nothing to show who he was. We've got the body in the mortuary. You can see it if you want. What did he look like? Tall, thin, sunburnt, poorly dressed. Artisan of some kind, I'd say. Obviously a foreigner. There wasn't any name on his clothing and there was nothing in his pockets except an apple and some string and a shilling map of London and a man's photograph.
