But figuring out the identity of the Christmas Crooks isn't the only mystery around. After all, Buckley had just been adopted from the cat shelter this year, and this was the first he'd ever heard about Christmas. And he quickly finds out there is a lot to learn! From Christmas trees to Santa Claus, and jingle bells to the birth of baby Jesus, the real meaning of Christmas is a mystery to him. But he and Bogey can't really enjoy any of it until the Christmas Crooks are caught. That's because it becomes very clear, very quick — these Christmas Crooks have set their sights on the boys' house, too! And the burglars are headed straight for their door. Holy Mackerel!
