The French Confection
Anthony Horowitz
 The Diamond Brothers win a dream holiday in Paris due to an award from a yoghurt company. On the train, they meet Erica Nice, a French baker, and Jed Mathis, a Texan oilman. The Diamond Brothers mention to them that they are staying at Hotel Le Chat Gris. The steward drops some coffee at hearing this. As the Diamond Brothers get off the train, they are met by the steward who tells them to beware of someone called the Mad American and hands them a sugar sachet. The steward is later pushed under a train. At the hotel, they see a man in gray who seems to be interested in them. Two thugs, Bastille and Lavache, accost the brothers in the street with a knife, and threateningly demand to know what the steward gave to them. While trying to get away from them, Nick and Tim jump from a bridge into a passing bateau mouche. They are locked up by the gendarmes but when they mention Bastille and Lavache they are hurriedly released. They return to find their hotel room has been turned upside down, soon after they are kidnapped and interrogated. They realize they are in a drugs factory, and Nick guesses that the sugar sachet must contain drugs. The criminals try to kill the brothers by giving them an overdose, but fortunately they are taken to hospital just in time, as the Police were out looking for them. The man in grey, who is from the Sûreté, asks for their help. He is revealed to be from a French company fighting against drugs, and says Le Chat Gris is sometimes used by the Mad American, meaning he thought the Brothers had come to buy drugs. Nick remembers some things about the place they were held and realises the place is in the Jewish Quarter, due to a blue star he saw, and they track down the Mad American - who turns out to be Madame Erica Nice. She is arrested for running a drug smuggling racket after Nick and Tim knock her out with a giant cake when entering her cake shop, 'The French Confection'.
