The dim glow of a single bulb swung over the rickety kitchen table like a hanged man. Crumpled blueprints of the community center lay between half-eaten pizza slices and three empty beer bottles. Molly leaned forward, her wild red curls nearly catching fire on the cigarette dangling from her lips. “Bill, I’m telling you, the bouncy castle is the key,” she said, tapping the crudely drawn map. “We cut through the back hedge at exactly six-fifteen, right after they sing Happy Birthday. The kids’ll be distracted by sugar and regret.” Bill rubbed his bald head, frowning at the cartoonish stick figures she’d labeled “screaming brats.” “Molly, love, we’re not robbing Fort Knox. We’re nicking presents from a six-year-old’s Paw Patrol party. You’re making this sound like Normandy.” She grinned, showing the gap between her front teeth. “Exactly. Nobody expects the Normandy of birthday parties. That’s our edge.” He sighed and picked up a plastic dinosaur party favor she’d swiped during recon. “Fine. We go in as the hired entertainers. I’ll be Professor Bubble, world-famous balloon artist. You be my lovely assistant, Miss Sparkles.” “Miss Sparkles?” Molly’s laugh was sharp enough to cut glass. “I’ll sparkles your arse if you call me that again. I’m the Great Mysteriosa, thank you very much. I do card tricks and light things on fire. Mostly the latter.” “Card tricks,” Bill repeated flatly. “At a children’s party. While we’re stealing every wrapped box in the building.” “Keeps the little monsters calm while you shove Barbie Dreamhouses into the duffel.” She waved a hand dismissively. “Besides, I’ve seen your balloon animals. They look like depressed weasels. Nobody’s hiring you twice.” Bill leaned back, folding his arms. “This whole thing is mental. What if one of them starts crying? I can’t handle crying kids, Mol. Last time I heard a toddler wail I nearly confessed to that post office job in ’09.” “Then don’t make them cry,” she said sweetly. “Offer them juice boxes. Kids’ll sell their own grandmas for a juice box.” He stared at her for a long moment. “You scare me sometimes. You know that?” “Good. Fear keeps you sharp.” Molly stubbed out her cigarette and slid a glittery invitation across the table. “Look, the birthday girl wants a magician. We give her one. While I’m pulling imaginary rabbits from a hat, you wheel the gift table out the side door like it’s on casters. In and out in seven minutes. Then we’re on a beach in Spain drinking something with an umbrella in it.” Bill picked up the invitation, which featured a cartoon unicorn wearing a party hat. He let out a long breath that sounded suspiciously like surrender. “If we get caught because you turned a toddler’s party into an episode of Ocean’s Eleven…” “…then I’ll take the fall,” Molly finished, eyes gleaming. “But we won’t get caught. We’re professionals, Bill. The best bloody present thieves this side of the playground.” He looked at the dinosaur in his hand, then at her manic grin, and finally at the ridiculous map covered in crayon and coffee stains. “God help us,” he muttered. “Miss Sparkles it is.”
