The case which i call 'The Norwood Builder' began for us in a very dramatic way. Holmes and i had just finished a late breakfast one morning, and we were talking in our sitting room in Baker Street. Holmses was about to open his morning newspaper, when we heard a lot of noise outside. A moment later, someone was knocking at the door, very hard. Then the door opened and a young man rushed in. His face was pale and his fair hair and his clothes were untidy. His blue eyes were frightened. He had obviously been running, and he was breathing heavily.
