Dr. Watson is called to tend Holmes, who is apparently dying of a rare tropical disease, Tapanuli fever, contracted while he was on a case. Watson is shocked, not having heard about his friend's illness. Mrs. Hudson says that Holmes has neither eaten nor drunk anything in three days.Holmes instructs Watson not to come near him, because the illness is highly infectious. In fact, he scorns to be treated by Watson and insults his abilities, astonishing and hurting the doctor. Although Watson wishes to examine Holmes himself or call in a specialist, Holmes demands that Watson wait several hours before seeking help. While Watson waits, he examines several objects in Holmes's room. Holmes grows angry when Watson touches items explaining that he does not like his things touched.
