The scandalous sisterhood of Prickwillow Place (First edition.)

The students of St. Etheldreda's School for Girls face a bothersome dilemma.

Their irascible headmistress, Mrs. Plackett, and her surly brother, Mr. Godding, have been most inconveniently poisoned at Sunday dinner.

Now the school will almost certainly be closed and the girls sent home-unless these seven very proper young ladies can hide the murders and convince their neighbours that nothing is wrong.
