Molly slid the blueprint across the table, a crumpled napkin with a birthday cake drawn in the corner. "You're telling me," Bill said, "our big score is a seven-year-old's birthday party." "Not just any party, Bill. The Hendricks party. Do you know how many presents rich people buy for one kid?" "I know how many years we'll get for stealing them." "Nobody goes to prison for stealing juice boxes and Nerf guns." Bill rubbed his temples. "There will be parents there. Clowns. Possibly a bounce house." "The bounce house is our exit strategy." "You want us to escape through a bounce house." "Obviously not through it. Behind it. There's a gate. I scouted it yesterday, dressed as a caterer." "You dressed as a caterer." "Best disguise there is. Nobody questions a woman carrying trays of cupcakes." "And the presents? Just gonna carry those out too, on a tray?" "Duffel bags, Bill. Under the gift table. We swap the real presents for empty boxes during the piñata." "The piñata." "Everyone watches the piñata. Works every time." Bill sighed, staring at the napkin. "We're stealing from children." Molly smiled, tucking the napkin into her jacket. "We're stealing from their parents. The kids get better presents from us later. Karma." "That's not how karma works." "It is today."
