The Adventure of the Red Circle explained

Mrs.

What happens

Mrs. Warren seeks Holmes's help regarding her mysterious lodger who never leaves his room and communicates only through printed notes. Holmes and Watson observe the lodger signaling from a window using a candle, interpreting the messages as Italian warnings. The signals abruptly stop, prompting them to investigate. They encounter Inspector Gregson and Pinkerton agent Leverton, who are tracking the notorious criminal Gorgiano of the Red Circle. The case culminates in the discovery of Gorgiano's body, killed by the lodger, who is revealed to be a woman in hiding, and the resolution of the threat.
