A Mystery That's Out Of This World . . .
Nancy, George, and Bess can't believe the out-of-this-world contest McCormick's grocery store is having - the kid who guesses the number of jellybeans in the jar wins a trip to a space camp!
Nancy is super-excited because she has been studying the stars and planets with her brand-new telescope, and space camp would be just the thing to test her new skills. But then the jellybean jar goes missing, and it looks like no one will get the chance to blast off to space camp. Who would steal a jellybean jar? Nancy must use her star-power detective skills to find out!
