Mysteries According to Humphrey: Betty Birney

To celebrate his tenth birthday the whole Humphrey series has a smart new livery, repositioning him alongside perennial favourites such as Winnie-the-Pooh and Paddington.

When Humphrey’s teacher, Mrs Brisbane, doesn’t come to school, he is unsqueakably worried. Then a supply teacher, the mysterious Mr E, arrives and everything changes. Class is fun, but are Humphrey’s classmates learning anything? And what had happened to their wonderful teacher?

Humphrey has his paws full as he tries to gather clues to solve the mystery, and then, on Halloween, everything is revealed . . .
