THE PLAYERS 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 it's 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. With pieces and players, you have all the ingredients for a fantastic mystery from the amazing Blue Balliett.
