Molly spread the crayon blueprint across the kitchen table, weighting the corners with empty coffee mugs and an uneaten bagel. The target was little Timmy Henderson's seventh birthday party, an event supposedly guarded by three exhausted parents, a teenage magician, and a hyperactive golden retriever named Biscuit. Bill leaned over her shoulder, squinting at the glittery map. "Bill, we need a clown disguise and a getaway stroller." Molly whispered without looking up, tracing the route from the bounce house to the towering pile of presents. Bill grinned and tapped the kitchen window where his rusted van waited. "Relax, I already bought balloons and a tiny ski mask." The plan was absurdly simple. Molly would distract the clown by pretending her shoe was untied while Bill infiltrated the gift table disguised as an unusually tall child. They had timed the magician's smoke trick to cover their escape. Outside, children's laughter echoed down the street as decorations inflated, unaware that the world's most incompetent criminals were about to attempt their most embarrassing heist yet. Unfortunately, neither had considered how to explain a screaming sack of action figures to suspicious neighborhood watch captains patrolling slowly outside in broad daylight without raising immediate alarms.
