Trixie Belden awoke slowly, with the sound of a summer rain beating against her window. She half-opened her eyes, stretched her arms above her head, and then, catching sight of a large sign tied to the foot of her bed, yelled out, “Rabbit! Rabbit!” She bounced out of bed and ran out of her room and down the hall. “I’ve finally done it!” she cried […] “Well, ever since I was Bobby’s age I’ve been trying to remember to say ‘Rabbit! Rabbit!’ and make a wish just before going to sleep on the last night of the month. If you say it again in the morning, before you’ve said another word, your wish comes true.”
