The story so far: Isabelle and her mysterious new chaperone board the Aerial Express and have dinner with the airship’s unpleasant owner, Julius Beechcraft, and other passengers. During the night, she overhears Captain Miro fighting with Beechcraft, who fires her old friend. The next morning, a maid discovers Beechcraft’s murder. Charging into the scene, Isabelle realizes that (1) someone tortured Beechcraft before his death and (2) her chaperone, Mrs. Darling, knows the owner’s secretary, Mr. Notti.
