INT. 221B BAKER STREET - SITTING ROOM - NIGHT
Rain against the glass. The fire is low. DR. MORTIMER (30s) has not taken off his coat.
SHERLOCK HOLMES (40s) does not look up from his pipe.
HOLMES
You saw footprints. A man’s or a woman’s?
Mortimer glances at the door, as if the moor might be standing behind it.
He leans in. The fire cracks.
MORTIMER
Mr. Holmes, they were the footprints of a gigantic hound!
For the first time tonight, Holmes puts down his pipe.
