Molly crouched behind the hedge opposite number forty-two, binoculars pressed to her eyes, her black wool hat slowly sliding down over one eyebrow. Across the road, a garden had been transformed into a riot of balloons, bunting, inflatable dinosaurs, and shrieking children. A banner read HAPPY 7TH BIRTHDAY, ALFIE! Beneath it sat a mountain of wrapped presents. Bill lay beside her on a tartan picnic blanket, eating crisps from a bag labeled For Emergencies. “That,” Molly whispered, “is the treasury.” Bill squinted. “Looks like a trampoline accident waiting to happen.” “Focus. We go in during the magician’s act. Everyone watches the rabbit. We collect the presents. We leave through the side gate.” “What if there isn’t a rabbit?” “There’s always a rabbit.” “Last magician I saw had a ferret.” “Then everyone watches the ferret.” Bill considered this. “I don’t trust ferrets. Too bendy.” Molly lowered the binoculars. “You don’t have to trust it. You have to ignore it.” A child in a superhero cape charged across the lawn, collided with a folding chair, and bounced off without slowing. Bill winced. “This is a dangerous crowd,” he said. “They’re seven.” “Exactly. No fear, no pensions, sticky hands.” Molly unfolded a creased map of the garden, drawn in purple crayon. “Entrance here, presents here, cake table here.” Bill leaned closer. “Why does the shed have teeth?” “That’s a drawing of the bouncy castle.” “Then why is it labeled Kevin?” “Because Alfie named it. Keep up.” The back door opened and a woman emerged carrying a cake shaped like a pirate ship. Twenty children screamed as if treasure had appeared from the heavens. Molly’s eyes narrowed. “Change of plan. Cake will create a sugar surge. We move before that.” Bill licked crisp dust from his thumb. “I thought we wanted distraction.” “We want distraction, not a stampede.” “I once got trapped in a ball pit at a christening. Took three adults and a priest to get me out.” “That was because you refused to let go of the buffet sausage.” “It was a matter of principle.” Molly tugged her hat straight. “Costumes?” Bill opened a sports bag and produced two striped shirts, paper hats, and a badge reading Party Helper. Molly stared. “Why does mine say ‘Mollusk’?” “Printer problem.” “And yours says ‘Bile.’” “Could be French.” From the garden came a collective gasp. A man in a purple cape had appeared, waving a wand. He placed a top hat on a small table and bowed. Molly grinned. “Magician. Told you.” Bill sat up. “If a ferret comes out, I’m leaving.” They crossed the road with the grave confidence of people making terrible decisions. At the gate, Molly lifted the latch. A small girl with face paint like a tiger blocked their path. “Who are you?” she demanded. Molly smiled brightly. “Party helpers.” The tiger girl examined their badges. “You’re called Mollusk?” “It’s short for Molly.” “What’s Bile short for?” Bill opened his mouth, then closed it. “William.” She nodded as though this made perfect sense. “You have to help with pass-the-parcel.” Molly froze. “We’re more present specialists.” “That is pass-the-parcel,” said the tiger. “Come on.” Before they could retreat, she seized Bill’s sleeve and dragged him toward a circle of children. Molly followed, hissing under her breath. “This is not in the plan.” Bill whispered back, “Neither was being interrogated by a tiger.” They were shoved onto tiny plastic chairs. Music began. A glittery parcel moved from child to child. Bill received it and panicked. “Do I keep it?” “No,” Molly said through her teeth. “Pass it.” “But we’re stealing presents.” “Not this one, Bill.” The music stopped. Bill was holding the parcel. Every child turned to stare. The magician clapped. “Open it!” Bill peeled away a layer. Inside was a sticker sheet of smiling dinosaurs. The children cheered. Bill looked strangely moved. “I’ve never won anything before,” he whispered. Molly watched his face soften, then glanced at the heap of presents, then at Alfie beaming beside his pirate cake. “Oh no,” she muttered. “What?” “I’m having a conscience.” Bill stuck a dinosaur sticker on his badge, covering Bile. “Can mine have crisps?” Molly sighed. “We are not stealing from children.” “Good. Because Kevin the bouncy castle is staring at me.” The tiger girl returned. “You’re funny. Can you help carry presents inside later?” Molly smiled weakly. “Yes. We can do that.” Bill nodded solemnly. “Professional present specialists.” And for the next hour, the two most unsuccessful thieves in town guarded Alfie’s gifts with terrifying devotion, confiscated three suspiciously damp sandwiches, and chased off a real fox that had taken an interest in the pirate ship cake.
