When a mystery man promises Celia £20,000 to retrieve a ring from the Fritton Archive in the school library the girls become suspicious, and sure enough Miss Fritton has a tale to tell that not even she had believed true - until now.
As a dastardly web of misogynist intrigue begins to entangle the school, its devoted staff and disparate bands of pupils rally together in search of clues to lead them toward a hoard of buried treasure. But they've got to move fast, because the duplicitous Sir Piers Pomfrey and his woman-hating cult, with connections from Government to industry and - yes - even Monarchy, are after the same prize.
Will the girls find the gold? Will they get there before Sir Piers? Is Annabelle really head girl material? Can Geoffrey Thwaite really be trusted to help them? And what's all of this got to do with Shakespeare anyway...?
