Molly spread the blueprint across the kitchen table, jabbing a finger at the crude drawing of a bouncy castle. Bill leaned over, squinting through his reading glasses, unconvinced by the entire operation. "A six-year-old's birthday party, Molly. This is rock bottom." "Presents, Bill. Do you know what parents buy these days? Drones. Tablets. Actual gold-plated Legos, apparently." "We're stealing from children." "We're stealing from Amazon Prime accounts. The children won't even remember by Tuesday." Bill crossed his arms, still skeptical, but Molly could see the greed flickering behind his eyes. "How do we even get past the clown?" "The clown is Debra from accounting. She owes me money. She'll let us in the side door." "And the parents?" "Distracted by a piñata I've rigged to explode early. Chaos, Bill. Beautiful, present-shielding chaos." He sighed, pulling off his glasses, rubbing his temples like a man already regretting tomorrow. "Fine. But I'm not wearing a costume this time." "You're wearing the dinosaur costume." "Molly—" "It has pockets, Bill. Big ones. For presents." He groaned, but reached for the tail already laid out on the chair, defeated by simple, practical villainy.
