Part of the Mabel Muttley Series.
There is treasure hidden in the school and the dastardly Councillor Cedric Scrimshanks wants to find it and take it for his own. But Mabel, the 109 year old primary school pupil, and best friend Jodie are determined to foil the foul plan and save the treasure for the school. It's a close call, but Mabel's special bell ringing technique raises the alarm and uncovers the long-lost treasure.
