New girl Millicent clashes with the feisty June over the school's priorities: a music concert or tennis tournament? But both pale into insignificance when it's found there's a thief in the fifth form.

This book is one of Pamela Cox's sequels to Enid Blyton's original Malory Towers series. Malory Towers is about everything school should stand for -- friendships, lessons, sports, plays and especially mischief.
