Molly tapped the blueprint of the Pembroke mansion. "The party starts at three. Every kid will be in the ballroom, and the presents will be stacked by the grand piano." Bill squinted at the sketch, chewing a stale licorice stick. "Stacked presents. Got it. How many guards?" "Just one clown, according to my cousin who catered the event. Balloon animals, face paint, a very intense temperament." "A clown." Bill shuddered. "I hate clowns. They always look like they're plotting something." "Focus, Bill. We slip in through the coat closet, grab everything with a bow on it, and leave before the cake is cut." "And if the clown spots us?" Molly pulled a wrapped box from her satchel and grinned. "Then we make him a balloon poodle and hope for the best." Bill sighed, adjusted his fake mustache, and reached for the ladder. "This is the worst heist I've ever planned." "That's what makes it perfect," Molly whispered, and they slipped into the night.
