Molly unfolded the blueprints across the hood of the van, smoothing them with gloved hands. The birthday banner fluttered in the distance, mocking them with its cheerful glitter. "Okay, Bill, the pinata goes down at fourteen hundred hours. That's our window." "Why are we whispering? We're four blocks away." "Method, Bill. We stay in character." She tapped the blueprint. "Clown enters here. Magician exits here. We slip in during the sack race." "And the presents?" "Stacked by the bouncy castle. Guarded by one grandma with a juice box." Bill squinted. "Grandmas are unpredictable, Molly. My cousin lost a tooth to a grandma in '09." "Which is why you're handling the diversion." "The diversion being?" "You. Dressed as Elmo." Bill stared at the crumpled red costume in the backseat. "That costume smells like regret and ham." "Focus. You distract the kids, I grab the loot, we're back in the van before anyone cuts the cake." "What about the parents?" "Wine table. Left unattended since noon." Bill sighed, zipping up the furry suit. "When I joined this crew, I pictured diamonds. Yachts. Maybe a Rembrandt." Molly smirked. "Dream bigger, Bill. Today, we steal Christmas in July."
