Hilton Cubitt, from Derbyshire, consults Holmes about a series of dancing men picture-messages his wife is receiving. On their wedding-day, she had made Cubitt promise he would ask her nothing about her past, but she now seems to be terrified. Holmes has to decipher the code of the matchstick men and get to the bottom of a dreadful murder which lies behind it.

Holmes is approached by Percy Phelps, of the Foreign Office, to recover a document which has been stolen - before it can cause an international scandal and ruin Phelps's career. It seems the British Empire and the Kingdom of Italy have entered into a secret and embarrassing treaty.
