ジョン・H・ワトスン
As they drive back to Baker Street, Holmes tells Dr. Watson how Adler showed him the hiding place as expected. He tells him that he plans on calling early the next morning at Briony Lodge as himself with the king and Dr. Watson to collect the photograph. While Holmes and Dr. Watson are about to enter their home on Baker Street, another coach stops nearby, and a person gets off. Only the person's shoes are seen. The person walks past Holmes and Dr. Watson and greets Holmes good night. By the time both of them turn around and look, the person is seen walking away rapidly with the back facing them.
