The third book in the Secret Academy of Spies series. On the first day of the new year at the spy school, thirteen-year-old Ben Ripley makes a huge blunder: he accidentally fires an active mortar in the principal's office and gets expelled. But when SPYDER shows up shortly afterward, offering him a position in their evil organization, he starts to suspect that something suspicious is going on. So he accepts.

As a new student at the diabolical SPYDER spy school, which trains kids to be bad spies, Ben acts as a secret double agent. He quickly realizes that SPYDER is planning something very big – and very bad. Will Ben be able to figure out what SPYDER is up to – and inform the good guys without getting caught – before it’s too late?
