Molly crouched behind the bakery van, watching the rainbow balloons bob above the hedge like smug little moons. Inside the garden, a troop of children shrieked around a castle of cake and curling paper, while parents attempted the heroic but doomed dance of supervising sugar. Bill adjusted his tie, which was patterned with tiny pickpockets. "Easy job," he whispered. "Easy," Molly said, peering through binoculars shaped like cupcakes. "We slip in, swap the gift tags, and roll out before the clown finishes his balloon swan." Bill frowned. "What if the clown is observant?" Molly snorted. "Then we distract him with a terrible joke and a larger hat." Their plan was elegant in the way all bad plans are elegant at a distance. Bill produced a clipboard, Molly a tray of juice boxes, and together they glided toward the gate like overqualified caterers. A toddler in a dinosaur crown pointed at them. Molly waved. "Presents audit," she said. The child accepted this with the calm authority of the very young. Behind them, the gift table gleamed: ribbons, bows, teddy bears, and a suspiciously heavy box that clearly contained something expensive enough to require secrecy and enough batteries to require revenge later.
