Altamont hands him the package. Von Bork finds that it is a book titled "Practical Handbook of Bee Culture", hardly what he expected. Even less expected is the chloroform-soaked rag that is held in his face by Altamont a moment later. Altamont is actually Sherlock Holmes in disguise, and the chauffeur who brought him is Dr. Watson. Now past their heyday, they have nonetheless caught several spies (Holmes is actually responsible for the imprisoned agents of whom "Altamont" spoke), and fed the Germans some thoroughly untrustworthy intelligence. Holmes had retired from detective work, spending his days beekeeping in the countryside, but returned after the Foreign Minister and the Premier came to him. Holmes has been on this case for two years, and it has taken him to Chicago, Buffalo, and Ireland, where he learnt to play the part of a bitter Irish-American, even gaining the credentials of a member of a secret society. He identified the security leak through which British secrets were reaching the Germans, and then set out to apprehend the receiving agents themselves. The housekeeper was one of Holmes' agents: the light that she switched off was the signal to Holmes and Watson that the coast was clear.
