British twins Rich and Jade Chance have come to accept that their father works for British Intelligence, but they’re not about to let him have all the adventures in the family. On their way to a vacation in Venice, John Chance completes a seemingly simple mission for his superiors by helping an accountant to super-crooks disappear into a new life. No mission is that easy, though. The accountant, code-named “The Banker,” turns up at the twins’ private school back in England, and in short order the school is taken over by The Banker’s former main client. Rich is kidnapped, and there seems to be a mole in John’s department. Rich and Jade use their wits to solve the case and do away with the bad guys. This second entry in Higgins and Richards’s British spy-teens series is just as much fun as the first (Sure Fire, 2007). These kids get by on ingenuity rather than with gadgets. There’s no deep character development, and some moments stretch believability, but fans of the series or the genre will be satisfied and ask for more. (Thriller. 10-14)
