Molly unfolded the blueprint across the laundromat table, pinning its corners with four suspiciously heavy socks. “According to this,” she whispered, “the birthday party begins at noon, the cake arrives at twelve-thirty, and the presents are stacked beneath the balloon arch.” Bill peered at the drawing. “Why is the balloon arch guarded by a cartoon dinosaur?” “That’s not a guard. That’s the entertainment.” “It has teeth.” “It’s wearing a party hat.” “So did my uncle at Christmas, and he still bit three people.” Outside, a delivery van rattled past, scattering pigeons and one elderly man who had apparently been waiting for a bus since 1987. Molly tapped the blueprint with a gloved finger. “The children’s entrance is on the east side. We slip in disguised as entertainers, locate the gift table, fill these bags, and leave before the magician starts.” “What are we disguised as?” “Clowns.” Bill stared at her. Molly stared back. “Fine,” he said. “But if anyone asks, I’m a balloon sculptor.” “You can’t sculpt balloons.” “I can make a tube.” “That’s not sculpture. That’s evidence.” They crossed the street at precisely eleven fifty-seven, carrying two enormous sacks and wearing matching red wigs. Molly had painted a smile on her face. Bill had painted one too, but his smile wandered toward his ear, giving him the expression of a man who had just remembered a very small crime. At the side gate, a woman with a clipboard blocked their path. “Names?” she asked. “Molly and Bill,” said Molly. “Performers?” “Absolutely,” said Bill. “We specialize in festive shapes.” The woman glanced at his empty hands. “Where are your balloons?” Bill patted his coat. A balloon squeaked somewhere inside it. “Sensitive equipment,” he said. She waved them through. The backyard seethed with children, frosting, and noise. A boy in a pirate hat chased a girl dressed as a fairy around a plastic slide. Near the table, a toddler sat solemnly beside the presents, guarding them with the grim authority of a tiny customs officer. Molly nudged Bill. “Stage one.” Bill approached the balloon arch and pulled out a red balloon. He inflated it with impressive confidence, twisted it twice, and produced something resembling a startled intestine. “What is it?” Molly murmured. “A dachshund.” “It has no head.” “It’s abstract.” Before she could answer, the birthday child spotted them. “Make me a sword!” “Of course,” Bill said. Within minutes, he was surrounded by eager children demanding swords, hats, giraffes, and one remarkably detailed representation of a grandmother. Molly drifted toward the gift table, but every time she reached for a package, another child handed Bill a balloon animal and asked for something more difficult. “Bill,” she hissed, “we’re here to steal presents.” “I know,” he whispered, wrestling a balloon into the shape of a swan. “But apparently I’m good at this.” The magician arrived early, saw Bill’s creations, and hired him on the spot. By sunset, Molly and Bill left with no presents, three unpaid balloon orders, and a thank-you card from the birthday child. Inside it was a crayon drawing of Bill’s abstract dachshund. He framed it.
