The van idled behind the bouncy castle hire shop, headlights off, engine wheezing like a retired accordion. Molly spread the blueprints across the dashboard while Bill chewed a stolen cupcake. "Party starts at three," she said. "Gifts are in the living room." Bill nodded, frosting smeared across his beard. He squinted at a sketch of the house, where someone had drawn a dinosaur guarding the back door in crayon. Molly ignored it. She had survived worse, including the time a grandmother bit her ankle during a bingo heist. "Remember," Molly whispered, "we're just uncles dropping off a present." Bill grinned and pulled a bright pink tutu from under his seat. "Lucky I brought the disguise." Molly sighed, tugged on her matching tutu, and checked the fake balloons clipped to the van's roof. Somewhere down the street, a child shrieked with joy, and both thieves grinned, already counting their loot.
