The van idled behind the Hendersons' garage, headlights off, its engine coughing like a grandfather at a funeral. Molly spread a blueprint across the dashboard while Bill chewed a sandwich he had clearly swiped from the party's catering table. "Presents are in the living room," Molly whispered. "Eight, maybe nine." Bill swallowed. "What about the bouncy castle?" Outside, a balloon drifted past the window, bobbing against the streetlight like a tiny, cheerful ghost. Somewhere inside the house, a child shrieked with joy, and both thieves flinched in unison. Molly pulled a ski mask over her curls and checked the tool bag. Glitter spilled onto the seat. Crowbar, zip ties, and a rubber duck she didn't remember packing. "We're stealing gifts, not souls," she said. "Keep up." Bill brushed crumbs from his coat. "Those boxes have puppies printed on them, Molly." She ignored him and eased open the door. Cold night air rushed in, carrying the smell of birthday cake and the distant bleat of a kazoo. A sprinkler ticked across the lawn, and a half-inflated unicorn sagged near the fence like it had given up on life. They crept toward the back gate, stepping carefully past a wobbling trampoline. Bill stopped to pocket a cupcake off a picnic table. "Mission first," Molly hissed. "Morale first," Bill replied, and bit into it.
