Molly studied the mansion through opera glasses, though it was only a rented clown castle and currently wobbling in the wind. Behind the plastic turrets, children shrieked around a mountain of presents, guarded by one exhausted magician and a Labrador wearing a paper crown. Bill adjusted his black mask, which had eyeholes in entirely the wrong places. “We sneak in as entertainers.” “We are not entertainers,” Molly whispered. “You once entertained a dentist for three hours with a kazoo.” “That was a hostage situation.” They crept toward the gate, carrying a suspiciously large sack labeled EMERGENCY BALLOONS. Molly had mapped every patrol route, including the Labrador’s predictable loop between the sausage rolls and the juice table. Bill, meanwhile, had brought a trombone. At the entrance, the magician blocked them. Molly instantly produced two glittering hats and announced they were the substitute magic act. The magician, desperate for a bathroom break, waved them inside. Bill tripped over a piñata, vanished beneath the refreshment table, and emerged wearing a princess cape. Molly began loading presents into the sack while explaining that her “vanishing gift trick” required temporary darkness. Then the birthday girl approached, clutching a teddy bear. “Are you stealing my presents?” Molly froze. Bill raised the trombone defensively. “Only the boring ones,” Molly said. The girl considered this, then pointed at a stack. “Start with the socks.” They obeyed, promoted from criminals to party staff.
