Dear Friends, I Love-Love-Love my job as the classroom hamster of Room 26. But when our teacher, Mrs Brisbane, didn't show up for school, I was unsqueakably worried about what had happened to her. Then a supply teacher, the mysterious Mr E, arrived and everything changed. Class was fun, but were my classmates learning anything? And what had happened to our wonderful teacher? I had my paws full as I gathered clues to solve the mystery and also tried to help my friends deal with their problems. At last, on Halloween, everything was revealed ...but in a frightful and delightful way! Your furry friend, Humphrey.
