Rain glazed the cul-de-sac until every bungalow looked gift-wrapped in cellophane. From behind a hedge, Molly studied the cheerful yellow house where balloons bobbed above a banner reading HAPPY SIXTH, PERCY! The birthday boy’s parents were inside, herding shrieking guests toward cake, while their dog conducted patrols beneath the windows. Bill crouched beside her, wearing a caterer’s apron over his burglar’s black turtleneck, an ensemble that made him resemble a depressed pudding. In his hands he held a clipboard bearing the forged words, “Emergency Balloon Safety Inspector.” Molly had spent the afternoon perfecting it, misspelling safety to suggest authority and urgency. “Remember, we are not stealing presents,” Molly whispered. “We are rescuing them from children who will immediately smash, chew, or trade them for stickers. Morally, we are a recycling service. Practically, we take the television-shaped parcels, the electronics, and anything that rattles without sounding alive. You smile now, Bill, please.” Beyond the hedge, a tiny pirate in plastic boots burst through the front door carrying a wrapped dinosaur. Three fairies pursued him, screaming that he had stolen it first. Molly watched the dispute with professional admiration; chaos was the velvet curtain behind which every successful crime preferred to enter quietly. “Smile?” Bill said. “At a children’s party? They can smell fear, Molly. Last time I smiled at a toddler, she bit my thumb and called me a taxman. Also, why are we taking presents after the cake? Wouldn’t it be simpler to take cake, delicious and comes without batteries too?” Molly adjusted the fake inspector’s badge pinned to Bill’s apron. It featured a cartoon balloon wearing a hardhat, which she had borrowed from a municipal website devoted to playground regulations. “Cake is evidence,” she said, though she slipped a paper napkin into her pocket with the concentration of a jewel appraiser. Bill’s eyes drifted toward the window, where an enormous cardboard treasure chest sat beneath the present table. It was labeled PRIZE FOR BEST PIRATE, but its taped seams bulged with the unmistakable geometry of a games console. Somewhere inside, a child began practicing a recorder, producing notes like alarmed geese. “Fine,” he said. “But if a child asks why I am inspecting balloons, I will say one has been radicalized. That sounds official. Then we grab the chest, the parcels, and perhaps one slice of evidence. You distract the parents with regulations. I distract the dog with sausage. Everybody respects sausage, especially during criminal educational visits, honestly.” At that moment, the front door opened, and Percy’s mother appeared carrying a tray of iced cupcakes. She beamed at Bill, read his clipboard, and thanked him for coming so promptly. Behind her, the dog sniffed Bill’s trouser leg, sneezed, and sat down with the grave expectation of a pensioner. Molly emerged from the hedge with a smile so dazzling it could have licensed products. She took the tray, announced that all balloons required immediate evacuation, and guided the delighted mother indoors. Bill followed, clutching the clipboard. Above the doorway, the banner fluttered bravely.
