Dr Watson has been abducted from the street and taken to an unknown address where a man who refused to identify himself warned him that Holmes' life is in grave danger; that the people who wish to keep the House of Silk a secret won't let his case come to court, and that the order has already been given that he must not leave prison alive.
Armed with the key to his friend's cell, Watson makes an appointment to visit the famous detective in the House of Correction.
