The Young, the Evil and the Savage

A woman is strangled in the bath by a black-gloved killer who disposes of her body in a large trunk. The trunk is delivered to St. Hilda College, an exclusive finishing school. Suspects include La Floret, the voyeuristic gardener; Di Brazzi, the new swimming instructor; Mrs. Clay, the summer school French mistress; an old professor who collects birds; and a philandering young teacher called Richard Barrett. As the murders continue, Jill, a keen amateur detective, helps the police identify the unlikely killer, ultimately leading to the revelation that Pierre, Lucille's cousin, has been disguising himself as Mrs. Clay and killing his relatives to capture their inheritance.
