When Lucia and her dad come to stay for a week, Idris hadn't prepared himself. Lucia loves spying and is convinced that Idris' mum is a spy. But even Idris has to admit that there is something unusual about their family trip to the zoo. Were his eyes playing tricks on him but did someone secretly drop something into his Mum's bag? And who is the Countess and what's happened to all the pangolins in the zoo? Maybe it IS time for some spying after all, so together Idris and Lucia go on the hunt for the answers.

In this episode Gregory Dobbs is joined by young podcaster Leo Grenfell who gives Andy McNab a real grilling on all things about spies. We find out if Andy has ever been a spy, how Andy and Jess French managed to write a book together, and what Leo himself would do if he was a spy.
