The final pieces feature Mycroft and his Umbrella. I dedicate this to Mark Gatiss.
Cut and pasted from Wikipedia:
Mycroft Holmes is a fictional character in the stories written by Arthur Conan Doyle. He is the elder brother (by seven years) of the famous detective Sherlock Holmes.
Possessing deductive powers exceeding even those of his younger brother, Mycroft is nonetheless incapable of performing detective work similar to that of Sherlock as he is unwilling to put in the physical effort necessary to bring cases to their conclusions.
Mycroft has appeared or been mentioned in four stories by Doyle: "The Greek Interpreter", "The Final Problem", "The Empty House" and "The Bruce-Partington Plans".
While he does occasionally exert himself in these stories on the behalf of his brother, he on the whole remains a sedentary problem-solver, providing solutions based on seemingly no evidence and trusting Sherlock to handle any of the practical details.
