Molly crouched behind the hydrangeas, peering through the garden fence at the riotous kingdom of balloons, streamers, and shrieking children beyond. A banner over the patio read HAPPY 6TH BIRTHDAY, SOPHIE! Beneath it sat a mountain of gifts wrapped in glittering paper. Bill adjusted his fake mustache, which had somehow attached itself to his eyebrow. “That is the most secure pile of presents I’ve ever seen,” he whispered. “It’s a children’s party, Bill, not a diamond vault.” “Exactly. Unpredictable guards. Sticky fingers. High-pitched alarms.” Molly unfolded a napkin on which she had drawn a crude map in ketchup. “We enter through the side gate during the magician’s finale. You distract the adults by pretending to be the replacement clown.” “I am not clown material.” “You’re wearing a purple waistcoat and a mustache on your forehead.” “That’s called natural charisma.” A boy in a pirate hat charged past the fence, waving a foam sword and screaming. Bill flattened himself against the soil. “See? Armed patrol.” Molly sighed. “Children are not guards.” “Tell that to my shin.” Across the lawn, a woman carried out a tray of cupcakes. Every child instantly swarmed her like pigeons discovering a dropped sandwich. The presents were momentarily unattended, except for a golden retriever asleep beside them wearing a party hat. “There,” Molly said. “Window of opportunity.” “The dog concerns me.” “He’s asleep.” “That’s what he wants us to think.” Molly tucked a coil of ribbon into her pocket. “Once inside, we load the presents into the laundry cart by the shed, wheel it to the alley, and vanish.” Bill squinted. “What about morality?” Molly looked at him. “What?” he said. “I’m just saying, they’re children.” “We are not keeping the presents. We are rescuing them.” “From being opened?” “From poor distribution. Look at that one. Clearly socks. No six-year-old deserves socks.” Bill considered this gravely. “A noble cause.” “Precisely.” At that moment, the magician shouted, “And now, for my greatest trick!” A puff of smoke erupted near the patio. Children screamed with delight. Adults clapped. The dog did not move. “Go,” Molly hissed. They slipped through the side gate and scuttled across the lawn. Bill attempted a jaunty clown wave at a grandmother, who waved back suspiciously. “You’re overdoing it,” Molly muttered. “I’m building character.” “Your character is wanted in three counties.” They reached the present pile. Molly grabbed a shimmering box with a bow the size of a cabbage. Bill lifted a bag covered in dinosaurs. The golden retriever opened one eye. “Hello, sir,” Bill whispered. “Lovely hat.” The dog thumped its tail once. Molly stacked gifts into the laundry cart. “Faster.” Bill froze, holding a package that began to sing “Happy Birthday” in tinny electronic tones. “Why is it doing that?” “Because you squeezed it.” “I was checking for traps.” A small girl in a princess dress appeared beside them, frosting on her nose. “Are you the present inspectors?” Molly blinked. Bill smiled too widely. “Yes,” Molly said. “Official.” The girl narrowed her eyes. “Then where are your stickers?” “Bill.” Bill patted his pockets and produced a sheet of gold star stickers from nowhere. Molly stared. “I prepare for everything,” he whispered. The girl accepted one solemnly, stuck it to the dog’s hat, and skipped away. “New plan,” Molly said, watching Sophie hug her grandmother. “We inspect for socks, rewrap anything tragic, and leave the rest.” Bill nodded, relieved. “The great birthday redistribution.” “And we eat one cupcake.” “Two. For realism.” By sunset, no presents were stolen, three sock boxes had become bubble wands, and Molly and Bill escaped over the fence with buttercream on their cheeks and a stolen reputation as the finest clowns Sophie had never hired.
