Molly spread the crayon blueprint across the hood of their getaway van which wheezed whenever Bill tapped the brakes too hard. The blueprint was not actually a blueprint but a drawing stolen from the refrigerator of the target's older brother, complete with stick figures and a lopsided bounce house labeled CASTLE OF DOOM. "We're really going to rob a six-year-old's birthday party, Molly?" "We are liberating overpriced plastic from parents who spent four hundred dollars on Paw Patrol wrapping paper." She weighed down the curling corners with stale juice boxes pilfered during reconnaissance. Bill stood beside her wearing his serious heist face which mostly just looked like constipation. He had cased the Johnson house for three days from behind a hedge while pretending to walk a borrowed dog that hated him. "That still sounds like we're stealing from children, just with extra steps." "Bill, focus. The Johnsons invited twenty kids. That's twenty presents. Minimum value, fifty bucks a pop. That's a thousand dollars in unopened Lego sets." The plan was simple because the party itself was chaos incarnate. At two o'clock twenty sugar saturated children would descend upon the backyard like locusts with party hats. Parents would be distracted by the clown who reportedly made balloon animals that looked more like existential crises. Somewhere near the patio the gift table would sit unattended for exactly seven minutes while everyone sang happy birthday off key. "And the security?" "One rent-a-clown, one bouncy castle, and a very tired dad guarding the gift table with a spatula." Molly tapped the bounce house drawing with a chipped purple fingernail. Her enthusiasm was surgical and slightly terrifying. Bill shifted his weight and stared at the dinosaur costume slumped in the back seat like a deflated god. "So we dress as what, entertainers? I don't do face paint." "You will wear the dinosaur costume. I will be the princess. We walk in, grab the loot, and waddle out before cake." The van smelled of vinyl and old french fries. Outside a neighborhood cat judged them silently from the fence. Molly folded the blueprint with criminal origami precision and shoved it into Bill's hands. He held it like it might explode into confetti. "I have to be the dinosaur? That suit smells like old cheese and regret." "You ate regret for breakfast. You'll survive. Remember, act magical." Behind them the dinosaur tail twitched as wind rattled the van doors. Somewhere down the street a child's laughter echoed and a lawn sprinkler hissed. It was the perfect cover for larceny involving juice boxes and questionable morals. They had robbed banks and museums but never a backyard where the vault was guarded by frosting. "Fine, but if I have to dance, I'm quitting crime." Molly grinned and opened the van's sliding door with a dramatic flourish. Duty called and it wore wrapping paper. Bill sighed and began squeezing into the scaly suit one reluctant leg at a time. The heist of the century was about to begin. At last.
