Molly crouched behind the hedge, peering through a gap in the bouncy castle at the glowing backyard. "Third window on the left, Bill. Balloons everywhere. Two hundred presents stacked by the piƱata." Bill adjusted his fake mustache. "Are we sure the kids are asleep?" "They're eight. They're on their fourth cupcake and a sugar-fueled dance-off. Nobody's sleeping." "Right. And the clown?" "Distracted. I paid him in glitter and a promise." Molly slid a crowbar from her coat. "Now listen. Blue wrapping paper goes in the van. Anything shaped like a pony goes too. Anything that rattles, we leave. It's probably socks." "Socks are a crime, Molly." Bill nodded solemnly, pulling a stocking over his head with great dignity. "Only when they're disguised as a gift." Bill froze as a small voice squeaked from the patio. "Who are you?" A tiny girl in a princess dress stared at them, clutching a juice box like a weapon. Molly smiled sweetly and lowered her voice, trying her best to sound jolly. "Santa's helpers, sweetheart. Go back to your cake." "Santa doesn't wear a ski mask." "Ssh. Bill, bag. Now."
