The Adventure of the Bruce Partington Plans

SHERLOCK HOLMES helps his brother Mycroft. An excerpt: It was the maid with a telegram. Holmes tore it open and burst out laughing. "Well, well! What next?" said he. "Brother Mycroft is coming round." "Why not?" I asked. "Why not? It is as if you met a tram-car coming down a country lane. Mycroft has his rails and he runs on them. His Pall Mall lodgings, the Diogenes Club, Whitehall--that is his cycle. Once, and only once, he has been here. What upheaval can possibly have derailed him?" "Does he not explain?" Holmes handed me his brother's telegram. Must see you over Cadogen West. Coming at once. Mycroft.
