Molly adjusted the binoculars, the cheap plastic lenses squeaking against the glass of the getaway van. Across the suburban street, a fluorescent bouncy castle inflated rhythmically like a neon lung. A man in a terrifyingly oversized polka-dot suit was currently twisting balloons into sword shapes for a horde of screaming six-year-olds. The hot sun beat down on the asphalt, creating shimmering heat waves that distorted the mailbox. "This is a high-stakes operation, Bill," Molly whispered, though the van windows were firmly rolled up. "We need precision. We need absolute stealth." Bill scratched his stubbled chin, leaving a dark smear of old engine grease. He stared hard at the driveway, his brow furrowed in intense concentration. "I still say we use the smoke grenades. Pop two in the kitchen, grab the haul while they choke on fog, and we are out." "They are children, Bill. We are stealing their birthday presents, not staging a tactical extraction. The plan is simple. We wait for the clown's finale, slip in through the side gate, and you grab the gift table." "What if the clown tries to stop us?" Bill asked. "I saw him make a hat in three seconds." "He is an actor named Greg. Just pick up the shiny box with the Lego set and walk." "Is that the Millennium Falcon?" Bill asked, leaning forward. "Yes, it is the Falcon. Do not shake it. Do not drop it. Just go." Molly shoved the door open. The summer heat hit them instantly, smelling of cut grass and vanilla frosting. Bill lumbered out, tugging his black sweater down over his belly. He looked entirely too suspicious, sweating profusely in eighty-degree weather while wearing thermal knitwear. Molly marched ahead, her sneakers silent on the sunbaked pavement. She moved with the practiced grace of a woman who had stolen priceless artifacts, though today the prize was a plastic spaceship. The wooden side gate was unlatched. Her informant, a nosy neighborhood Facebook group, had provided a highly detailed itinerary of the party. Molly peeked through the slats. The gift table was completely unguarded, a precarious mountain of glossy paper sitting ten feet away from the cupcakes. She signaled to Bill, who was currently struggling to untangle his sleeve from a rosebush. He finally broke free, tearing a small hole in his expensive sweater, and gave her a clumsy thumbs up. Molly eased the gate open, wincing at the metallic screech of the hinges. The clown pulled a massive red balloon from his pocket, and the children gasped in unison, their backs turned to the loot. It was the perfect window. Bill squeezed through, his shoulder catching the latch with a loud clack. Molly winced. Greg the clown stopped mid-twist, slowly turning his painted head toward the fence. The party music seemed to skip a beat. "I told you to be quiet now," Molly hissed. "It was the rusty gate," Bill whispered back defensively. "It literally jumped out and attacked my shoulder."
