Molly spread the blueprints across the hood of their stolen ice cream van, pinning the corners with a squashed cupcake and a stapler. "Phase one: we slip through the back gate while the magician is busy with his balloon swords." Bill snapped on a rubber clown nose and gave it a nervous honk. "Why am I always the clown?" "Because nobody ever checks a clown's pockets." She tapped the paper. "The presents are stacked on the patio, wrapped in glitter paper with enormous bows. We grab everything and drive." Bill squinted at the bouncy castle, where toddlers shrieked like seagulls over a dropped chip. "What about the kids?" "Easy. We bribe them with a piñata. Nobody has ever resisted a piñata." "Last time I tried that, a six-year-old swindled me out of my wristwatch for one lollipop." Molly sighed deeply, folded the map into a tiny, tragic square, and stuffed it into her boot. "Look, Bill, this is the cleanest heist of the year. Nobody gets hurt, and nobody will even notice." A balloon popped somewhere behind the hedge with a sound like a gunshot. Both thieves dove headfirst behind the van, shrieking louder than any toddler at the party.
