Holmes refuses to allow Watson to examine him. Instead, Holmes tells Watson to bring a man called Culverton Smith to see him. Culverton Smith has no professional medical training but he knows more about the disease which Holmes claims to be suffering from than anyone else in the world. Holmes admits that he and Culverton Smith are not on friendly terms because Holmes suspected that the man had some part in the death of his nephew.
