Molly adjusted her fake clown nose and whispered, “Bill, this is insane. We’re breaking into a six-year-old’s birthday party. There are balloons, not guards.” Bill peered through the hedge at the bouncy castle. “Exactly. Kids are distracted, parents half-drunk on juice boxes. It’s the perfect score. We grab the gift table, run like hell.” “I still say the piñata’s a better target,” Molly muttered. “Smash it open, candy and presents everywhere. Chaos is our friend.” “Too loud. We go in during musical chairs. I’ll wear the giant teddy bear costume. You be the weepy aunt who lost her invitation.” Molly snorted. “I’m not crying on command for a bunch of Barbies and Transformers.” “Fine, then you wear the bear. I’ll do the crying. I’ve got range.” She rolled her eyes. “We split the haul fifty-fifty. No calling dibs on the PlayStation like last time.” “Deal. But I get first pick of the chocolate cake. Heist rule.” “Only if you don’t trip over your own giant fuzzy feet again, you oaf.” Bill grinned. “Hey, those feet saved us in Cincinnati.” “Those feet got us banned from three states. Now shut up and practice your toddler tantrum. The party starts in ten.”
