Summary: Some German spy is about to leave the country with secrets and he meets with his American (US) contact to exchange money/secrets, but the American turns out to be Sherlock–and old Sherlock, apparently, who has come out of retirement from watching bees just to catch this guy. And he does.
Sherlock Rating: 2 out of 5 magnifying glasses. Eh. It was okay. Predictable, and missing the investigation part of the story. It only really showed the “reveal” part where Sherlock comes out of his disguise and collars the guy, so there wasn’t any “mystery” to it, or excitement either.
Mystery Story Convention: The detective who had been in disguise/undercover and arrests the bad guy right when he thinks he’s going to get away with it.
