 Mrs Cosie s tearoom is a haven of peace and comfort for Miss Cackle, full of delicious goodies. It is, however, strictly out-of-bounds to the girls of the Academy. This doesn t deter Mildred and her gang, who are keen to stem their hunger pangs and take advantage of a free cake promotion. Unseen by Miss Cackle, the girls settle down at a table where they overhear a plan to trick Miss Cosie into selling her tearooms so that a toxic incinerator can be built on the site. This would make life unbearable for the inhabitants of Miss Cackle s - to say nothing about the wildlife. Can Mildred prevent Mrs. Cosie from signing the tearooms away and, more importantly, an the girls avoid being caught out-of-bounds by Miss Cackle and the stickler Miss Hardbroom?
