A package arrives at Arf’s house, but it’s not for him. It’s for his neighbor, Bill Bott. Arf’s curiosity gets the better of him, and he takes a peek, then, a bigger peek, until pretty soon, the box is open, and the metal detector that was in the box is in Arf’s hands. Wow - think what you could do with a metal detector! Buried treasure? Arf makes a plan, and it doesn’t include stolen gold necklaces or police or a tricky band of thieves.
