Molly spread the map across the café table with the solemnity of a general planning a siege. Unfortunately, the map was a crayon drawing she had stolen from the community center noticeboard, and the “fortress” was Mrs. Puddlewick’s back garden, currently labeled in purple as BIRTHDAY FUN ZONE. Bill squinted at it over his teacup. His hat was pulled low, though not low enough to hide the balloon animal tied to the brim from their earlier reconnaissance. “That’s not a moat,” he said. “It says ‘duck pond.’ Same principle.” “It says ‘duck pond, no swimming, love from Uncle Terry.’” Molly tapped the paper. “Focus, Bill. At three o’clock, the children will be distracted by the magician. At three-oh-five, the magician will discover his rabbit has unionized. At three-oh-six, chaos.” Bill nodded gravely. “And we enter disguised as?” “Entertainers.” He looked down at the striped trousers Molly had forced him to wear. “I look like a deckchair with debts.” “You look festive. Festive is invisible at a children’s party.” Outside the café window, rain slid down the glass in gloomy ribbons. Across the street, Mrs. Puddlewick’s house beamed with bunting, balloons, and the dangerous optimism of parents who had hired a face painter. Through the hedge, Molly could see a mountain of presents stacked beneath a gazebo: glossy boxes, silver bags, ribbons curled like taunting mustaches. Bill whistled softly. “That’s a lot of presents.” “A kingdom of presents.” “Probably socks in half of them.” “Children don’t get socks, Bill. They get robots, rockets, and things that make noises until fathers weep.” He considered this. “What if there’s a puppy?” “We don’t steal puppies.” “Good. I’m allergic to guilt.” Molly produced two badges from her coat pocket. One read Official Party Helper. The other read Official Party Helpr, the second e having fallen off. “You’ll be Helpr,” she said. “Why am I always the misspelled one?” “Because you panic near laminators.” Bill pinned it on upside down. “What’s the exit strategy?” Molly leaned closer. “We load the presents into the laundry cart behind the shed, wheel it through the side gate, and vanish behind the bouncy castle.” “The bouncy castle is bright orange.” “Exactly. Nobody suspects bright orange.” At that moment, the café door opened and a small girl in a glittery crown marched in with the force of a tax inspector. She carried a clipboard covered in stickers and wore an expression that suggested she had already seen through several international conspiracies before breakfast. Molly folded the map too quickly. Bill tried to hide his badge in his tea. The girl stopped beside them. “Are you the clowns?” Bill coughed. “Emotionally, yes.” Molly smiled with all the charm of a fox wearing reading glasses. “We’re party helpers, dear.” The girl narrowed her eyes. “Mummy says helpers don’t sit in cafés whispering about stealing presents.” A silence dropped onto the table. Bill raised one finger. “In our defense, the whispering was very professional.” Molly kicked him under the table. The girl leaned in. “I’m Emily. It’s my party.” “Happy birthday,” Molly said weakly. Emily studied them both, then the crayon map, then Bill’s upside-down badge. “If you try to steal my presents, I’ll tell Grandpa.” Bill swallowed. “Is Grandpa large?” “He used to wrestle bears.” Molly blinked. “Used to?” “He says they’re too political now.” Another silence. Emily’s face softened, but only slightly. “However, I do need help.” Molly and Bill exchanged a glance, the criminal kind that meant either opportunity or doom, usually both. “What sort of help?” Molly asked. Emily pointed toward the garden. “Cousin Toby has trapped the magician in the bouncy castle, the face painter is crying, and someone gave me a recorder.” Bill shuddered. “A recorder? At a party?” “Three of them,” Emily said. “If you help fix it, I won’t have Grandpa turn you inside out.” Molly looked at the presents again. They gleamed beneath the gazebo, innocent and impossible. Then a shriek came from the garden, followed by the unmistakable honk of a distressed magician. Bill sighed. “We’re going straight, aren’t we?” “For twenty minutes,” Molly said, standing. “Maybe thirty if there’s cake.” Emily handed Bill a stack of napkins and Molly a plastic wand. Together, the thieves followed the birthday girl into battle, past the balloons, toward the chaos. Behind them, the crayon map lay abandoned on the café table, its purple duck pond slowly absorbing a ring of tea.
