Question: In the first season, Hastings tells Arnott he's Catholic - but then in subsequent seasons he's supposed to be a Mason. Except the Catholic church considers joining the Masons to be a sin - is that a clue to Hastings' real status?
Question: How did Holmes know where M was, so he could have found him and taken him away? And how did Holmes transport M on his own? Was M unconscious, or alert and thus went where Holmes told him to go, or he'd kill him? But M wouldn't do that; he doesn't mind dying.
Chosen answer: M broke into the brownstone and left a note. Holmes deduced he was staying at a high-class hotel from the soap scent on the note, and gave a picture from a hidden camera to his "irregulars" on the street to stake out hotels. One of them saw him, so Holmes followed him to his next intended victim and knocked him unconscious with a baton.
Chosen answer: "C'mon Doll" by My Goodness.
