Publisher's Synopsis
13 extremely valuable pieces of art have been stolen from one of the most secretive museums in the world. A Vermeer has vanished. A Degas has disappeared. And nobody has any idea where they and the other 11 artworks might be - or who might have stolen them. Calder, Petra and Tommy are no strangers to heists and puzzles. Now they've been matched with two new sleuths, Zoomy, a very thin boy with very thick glasses, and Early, a girl who treasures words - and has a word or two to say about the missing treasure. The kids have been drawn in by the very mysterious Mrs Sharpe, who may be playing her own kind of game with the clues. And its not just Mrs Sharpe who's acting suspiciously - there's a ghost who mingles with the guards in the museum, a cat who acts like a spy, and bystanders in black jackets who keep popping up.
