Molly crouched behind the hedge opposite the community hall, peering through a pair of opera glasses she’d stolen from an opera singer who had been too busy singing about betrayal to notice. “Bill,” she said, “this is the job of a lifetime.” Bill, who was wearing a party hat over his balaclava, frowned. “It’s a children’s birthday party, Molly.” “Exactly. High volume. Low security. Emotional chaos. Cake-based distractions.” “We are not stealing presents from children.” “We are redistributing mystery boxes before they can be wasted on sticky little amateurs.” “That is the worst thing you’ve ever said, and I once heard you describe a pensioner’s handbag as ‘a portable investment opportunity.’” Molly lowered the glasses. “Fine. Morals. Tedious, but fine. We’ll only steal the presents from the adults.” “The adults haven’t got presents.” “They’ve got phones, wallets, dignity.” “No.” Inside the hall, a magician produced a dove from a pan, dropped the pan, and chased the dove into a balloon arch. Thirty children screamed with delight. Molly’s eyes shone. “You see? Perfect cover.” Bill folded his arms. “We came here because you said there was a vault.” “There is a vault.” “That’s a bouncy castle.” “It’s inflated. It has walls. It contains treasure.” “It contains seven-year-olds.” “Small guards.” “Molly.” “What?” “We’re not robbing a birthday party.” She sighed dramatically, the sigh of a woman denied both profit and spectacle. “Then why did you bring the crowbar?” Bill glanced down at the crowbar in his hand. “For the piñata.” “You brought a crowbar to a piñata?” “You brought smoke pellets.” “They’re party poppers with ambition.” At the hall entrance, a woman in a unicorn sweater struggled with a tower of wrapped gifts. One slipped from the pile and tumbled onto the pavement. Molly perked up. “Loose package. No witnesses.” Bill grabbed her sleeve. “No.” “But it’s unattended.” “A mother dropped it.” “So it’s free-range.” Bill marched across the street, picked up the fallen present, and handed it back. The woman beamed. “Oh, thank you! Are you two entertainers?” Molly opened her mouth. Bill answered quickly. “Yes.” “We’re the… surprise helpers,” Molly added, recovering. “Specialists in gift logistics.” “How lovely! Could you bring those inside?” Bill gave Molly a warning look. Molly gave him an innocent smile, which on her face looked like a forged passport. They carried presents into the hall. Children thundered past them in paper crowns. A boy with blue icing on his chin pointed at Bill. “Are you a burglar?” Bill froze. Molly leaned down. “No, darling. He’s a lesson.” The boy accepted this and ran away. Bill whispered, “We leave now.” Molly whispered, “We are behind enemy lines.” “We are beside the sausage rolls.” “That’s how they lull you.” The unicorn-sweater woman clapped. “Wonderful, put them by the table. Then perhaps you can help with games?” “Games?” Bill said. “Yes! Pass the parcel.” Molly stared at the mountain of presents, then at Bill. “Pass the parcel,” she murmured. “A controlled transfer of wrapped assets. I respect it.” Bill nudged her. “Behave.” “I am behaving. I haven’t stolen anything.” “Your hand is in that gift bag.” “It fell there.” She withdrew a squeaky toy. It squeaked accusingly. Bill snatched it and put it back. “Molly.” “What if we improve the party instead?” “That sounds dangerous.” “No, listen. We help them. We earn trust. We leave with cake.” “That is not a heist.” “It’s a cake heist.” Bill considered. “Cake is victimless if offered.” “Exactly.” Two hours later, Molly was running musical statues with the intensity of a bank raid commander, while Bill guarded the gift table from a toddler attempting to unwrap everything with his teeth. “No one touches the parcels before authorization,” Bill told him. The toddler hissed. Molly blew a whistle. “Freeze! Excellent stillness, Amelia. Terrible stillness, Bill.” “I’m not playing.” “You moved your eyebrow.” At last, the birthday child opened presents. Molly and Bill stood by the wall with paper plates sagging under cake. Molly watched the children cheer over crayons, dinosaurs, and a plush octopus. Her expression softened. Bill noticed. “Still want to steal them?” Molly sniffed. “Obviously not.” “Good.” “I’d only disappoint myself. Half of them are noisy.” Bill smiled. The unicorn-sweater woman hurried over. “You two were wonderful. I don’t know what we’d have done without you.” She handed Molly an envelope. Molly narrowed her eyes. “What’s this?” “Payment.” Bill blinked. “Payment?” “For entertaining. And helping. You saved the party.” Molly opened the envelope and counted the notes. Slowly, a grin spread across her face. Bill groaned. “Don’t say it.” Molly tucked the money into her coat. “Bill, we just robbed them legally.” “We worked.” “With disguises.” “They were party hats.” “And false identities.” “We said helpers.” Molly lifted her cake plate in triumph. “The perfect crime.” Bill took a bite of sponge. “Next time we rob a library.” Molly brightened. “Finally. A place with proper loot.” “Books, Molly.” “Yes,” she said, already dreaming. “Quiet little rectangular hostages.”
