'She works 50 hours a week at Bingo Blott's Paperclip factory. When would she have time to be a spy?'

A mum having a secret life full of action, adventure and intrigue? How can that be?!

But after an unusual trip to the zoo, Idris isn't so sure... Were his eyes playing tricks on him, or did someone really drop something into Mum's bag? And why is Budi the orangutan, who is normally so cheerful, suddenly off his food? Maybe it's time for some spying after all.

Andy McNab (yes, that definitely-not-a-spy author) and Jess French (almost certainly a vet, TV presenter and international woman of mystery children's author) join forces in this fun action-packed adventure!

Perfect for readers age 7+, spies, detectives, mystery solvers and puzzle lovers alike!
