Bill crouched beside the minivan, adjusting a suction-cup mustache he’d stolen from a Halloween store. Molly checked the map, then checked the snack table nearby, as if the cookies might bribe the security system. The house belonged to a kid named Preston, whose parents had advertised “all ages” on the invitation, which Bill interpreted as “all exits, please.” He tapped his earbud; only the faint jingle of party favors answered back. “Molly, quiet. The clown’s nose has lasers,” Bill said. Molly rolled her eyes, pulled a glittery lockpick from her sock, and demonstrated its aerodynamic qualities by flicking it into the air. It landed perfectly in a potted fern, somehow looking intentional. She leaned toward the front door, listening to the muffled squeals of toddlers sprinting in circles. “Relax, Bill. Tonight we win, and kids love theft,” Molly whispered. Bill grinned, then remembered the part where they had to look like harmless helpers. He practiced his “friendly uncle” smile until it resembled a warning label. Molly arranged their gear into a decoy gift bag labeled THANKS, which immediately attracted a nosy balloon animal. Bill whispered to the balloon to stand guard. The balloon nodded, because balloons never argue. Together they drifted toward the doorstep, stepping carefully over chalk arrows that pointed toward the presents like a target.
