Molly crouched behind the hedge, wearing a clown wig, burglar mask, and the expression of someone betrayed by balloons. Beside her, Bill wore a cape made from wrapping paper scraps. "Map says presents by the cake," she whispered. Bill held binoculars backward. "Map says your nose is enormous." "That's the wig." "Then your wig is plotting." "Focus. We enter during musical chairs." "I hate musical chairs. Chairs move like sharks." "Those are children moving them." "Children with frosting strength." Across the lawn, parents sang, hats bobbing like tiny crowns. A dog in a tutu guarded the gift table with sleepy authority. Molly unfolded a napkin blueprint. "You distract Princess Fluffykins." "With charm?" "With sausages." "I brought confetti, lockpicks, and a cheese stick." "Close enough." "The cheese stick is emotional support." "Fine, support her emotionally." A herd of toddlers thundered past, waving foam swords and shrieking about treasure. Bill flattened himself into the privet. "We're doomed," he said. "They already have pirates." "Perfect. We join the crew." "They'll smell adult fear." "Then smile smaller." Molly placed paper hats on them both. Bill's read Birthday Unicorn. "I demand a better codename." "Too late, Unicorn. Operation Sticky Fingers begins." They crawled forward, glittering disgracefully.
