Jake's dad is head of the Secret Service. Alice's dad is a double agent. Harry's dad has infiltrated SPUD - the Secret Partners for Undertaking Destruction. And Alfie's dad. . . is a postman.
Thunder Raker Manor is a very exclusive school. All the pupils are there because their parents or guardians are agents and spies.
All except one.
Because eight-year-old Alfie's dad isn't anything to do with the secret services. He's the local postman who just reckoned that Thunder Raker Manor was a great school. So when the Head Teacher receives a letter from the Prime Minister saying that Alfie has been given a special place and will start immediately, he isn't to know that Alfie's dad wrote it and slipped it in with the 'special' post. . .
Now Alfie has to get to grips with Thunder Raker's unusual curriculum and some even stranger new friends. He's got classes in camouflage (if anyone can ever find Mr Trick) and Assassination (only kids keep going missing from Miss Fortune's class). And he's now in permanent danger from SPUD agents. But to his surprise, Alfie finds that he might just be quite good at this spying game. . .

A hilarious new series for younger readers, following the misadventures of an ordinary boy at an extraordinary school for young spies. . .
SPUD has set up a secret base under the school pond and is using radio-controlled duck-cameras to gather information. But the chief SPUD agent has made the mistake of having his weekly edition of SPUD's Nasty Newsletter redirected to his new base - by Alfie's dad, the local postman! It doesn't take long for the gang to work out what SPUD are up to.
Can Alfie and his friends find a way of turning the SPUD infiltration to their advantage? Of course they can - and soon the school is teaching the pupils using even more bizarre methods than usual, all for SPUD's benefit. Will the evil organisation really believe in assassination by daffodil? Or that trained hamsters are used to infiltrate their bases? Of course they will. . .
