The scene opens with Dr. Watson and Holmes driving to Briony Lodge. It is night and Holmes is in the disguise of a clergyman. Holmes tells Dr. Watson that he plans on letting Irene herself show him where the photograph is kept, an idea that Dr. Watson finds amusing and hard to believe. They leave the cab a little distance before Briony Lodge. Quite a few people are seen meandering along the street. Holmes asks Dr. Watson to follow the instructions he has already given him - to act as soon as Holmes raises his hand.
