A wealthy family lived in a big circular house. They had a maid, a butler, and a gardener. The parents were going to a party, so they tucked the younger kids into bed and kissed them goodnight and said goodbye, and kissed the older kids goodnight. When the parents came home, all the kids were gone—they had been kidnapped. The authorities ask the butler, maid, and gardener what they were doing at the time of the kidnapping. The butler says he was organizing the library, the maid says she was dusting the corners, and the gardener says he was watering the plants. Who’s lying and actually kidnapped the kids?​
