Rain hammered the van roof while Molly studied the community center through binoculars. Inside, a princess bounced past a castle cake. Bill tightened his clown nose and checked the napkin floor plan. The getaway van smelled like crayons and stale juice boxes. A piƱata donkey swayed above a mountain of wrapped gifts. Molly adjusted her rainbow wig and pocketed a lockpick. Bill grinned. Outside, tiny voices sang off-key. They waited. Molly said, "Six-year-old birthday. Twenty kids. Many presents." Bill said, "Security?" Molly said, "A retired magician and a bouncy castle." Bill said, "We enter as entertainers. You juggle, I balloon." Molly said, "You made a sword once. Three toddlers cried." Bill said, "Artistic tension. The gifts are behind the cake table." Molly said, "What about the ball pit?" Bill said, "Trap. Swallowed a toddler last month." Molly said, "Perfect distraction. We strike at candle time." Bill said, "If the magician asks, we are cousins." Molly said, "Would you prefer the ball pit sleight of hand?" Bill said, "Never. I still smell like plastic balls." Molly said, "Then stop complaining and tie the balloon sword." Molly said, "Bill, we are stealing from children." Bill said, "Exactly. They have no legal standing."
