Molly spread the blueprint across the table, tracing her finger along a dotted line that led to the back patio. "So the presents are on the gift table, right by the bounce house," she said. "We slip in during the piñata chaos, grab the loot, and slip out." Bill frowned at the paper like it had personally offended him. "You want us to rob a seven-year-old's birthday party." "Not just any seven-year-old. Tiffany Huxley-Vance. Her dad owns half the shipping containers in this city. You think those presents are Lego sets? That's jewelry, Bill. Watches. Cash in envelopes from rich aunts who don't know what kids like." "And the piñata?" "Distraction. Every kid in that yard will be scrambling for candy. Nobody's watching a gift table when there's a unicorn exploding overhead." Bill rubbed his chin. "What about the clown?" "Bribe him. Fifty bucks and he does an extra-long balloon animal set." "You've thought about this." "I think about everything." Molly rolled up the blueprint, smirking. "Besides, what's the worst that happens? A bunch of six-year-olds tackle us for a Nerf gun?" Bill sighed. "Fine. But I'm not wearing the mascot costume again." "You looked adorable as a bear."
