It was a quarter-past nine when I started from home and made my way across the Park, and so through Oxford Street to Baker Street. Two hansoms were standing at the door, and as I entered the passage I heard the sound of voices from above. On entering his room, I found Holmes in animated conversation with two men, one of whom I recognised as Peter Jones, the official police agent, while the other was a long, thin, sad-faced man, with a very shiny hat and oppressively respectable frock-coat.
