Archie Blake thought his policeman father teaching him how to pick locks and open safes was just a bit of fun. But when a diamond necklace is stolen and his dad is arrested, Archie realises the only way to prove Dad’s innocence is to go on the run and use everything he’s learned to uncover the truth. But Archie soon finds himself deeply tangled in the criminal underworld, where it’s hard to know who to trust and even harder to see what’s right or wrong. Will Archie be able to find a way out before it’s too late?

Simon Fox lives in Sussex with his extraordinarily patient wife and two teenage children who never tidy their rooms but would take on the world for each other. Before becoming a writer, he worked as an accountant. He is determined to never go back.

The activity pack includes stickers, book club-style questions to ponder and a welcome note from Simon Fox. There’s also a codebreaker to solve and a 3D puzzle craft project to have fun with, alongside jokes and further reading recommendations.

Activity packs are a handy A5 size and printed on uncoated paper which is fully recyclable.

We are a monthly book subscription by post for children aged 5 to 14, focused on helping families discover new and different chapter books.

This title was sent to subscribers in the Macaw reading group, aged roughly 12 to 14, who need books that feel grown-up but aren’t quite ready for all young adult books.
