For new girl Darrell Rivers, there are friends to be made, pranks to be played and fun to be had at Malory Towers in Enid Blyton's best-loved boarding school series.

In book nine, Susan's in charge of the winter concert, but new teacher, Miss Tallant, won't let her make any decisions. When Miss interferes in a midnight feast, the girls realise that there's a spy in their midst.

Expect more drama at Malory Towers!
