The Adventure of the Dying Detective

"The Adventure of the Dying Detective", in some editions simply titled "The Dying Detective" (first published 1913), is one of the 56 Sherlock Holmes short stories written by Sir Arthur Conan Doyle. Together with seven other stories, it is collected as His Last Bow (published 1917).
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.
