With a runaway lion loose in the neighbourhood, Derrick, Samantha and Michael feel scared. Nanny Piggins feels like a slice of cake. And Boris feels like that lion looks strangely familiar.In this third action-packed book of adventures, Nanny Piggins tames a lion and a lion tamer. She revolutionises the sport of ski jumping, introduces hot-pink leotards to the local Neighbourhood Watch, demonstrates trapeze skills on a moving bus, plays badminton with a wok and teaches Shakespeare a thing or two about how to write a play. All while thwarting Mr Greens attempt to send her favourite children to Nicaragua (she does find it wearisome having to put him in his place constantly). And yet, somehow, she still finds time to bake lots and lots of cake.
