Description:

When brothers Scott and Jack Carter are packed off to spend the summer with their great-aunt, they're convinced it'll be the most boring holiday imaginable. But everything changes the moment they meet adventurous local girl Emily Wild and her loveable dog, Drift. Emily shows them the island's lighthouse, its clifftop castle, and the famous whistling caves — and reveals an old legend: when the caves fall silent, the castle will be attacked. Sure enough, the caves go quiet, and priceless treasures vanish from the castle! Determined to crack the case, the three friends set out to discover how the loot was smuggled away, why the caves stopped whistling, and who's behind it all — before the thief slips away for good. The first in a thrilling, Blyton-style mystery series, this fast-paced page-turner is packed with secret passages, clues, and old-fashioned adventure.
