Molly spread the blueprint across the table, smoothing its wrinkled corners. "The bouncy castle is here. That's our entry point." Bill squinted. "We're crawling through a bouncy castle?" "Through it, under it, around it. Whatever it takes." "And the guards?" "Two clowns and a magician," Molly said. "The magician's the dangerous one." Bill laughed nervously. "Dangerous how? He's gonna pull a rabbit on us?" "Don't underestimate close-up magic, Bill. The man can palm a quarter. Imagine what he does with handcuffs." Bill swallowed hard, tapping the diagram. "What about the loot? Where do they stash the presents?" "Pile in the corner. Wrapped, bowed, completely unguarded except for one thing." "Which is?" "Forty screaming six-year-olds hopped up on birthday cake." Bill paled. "That's a war zone." "That's an opportunity," Molly corrected. "Chaos is our friend. We move during the piñata." "The piñata?" "Blindfolds, swinging bats, candy raining down. Total pandemonium." She grinned. "Nobody's watching the gift table when free candy's involved." Bill rubbed his temples. "Molly, we've robbed banks. Casinos. Now we're stealing from toddlers?" "Those toddlers," Molly said coldly, "have a brand-new gaming console in that pile. Retail value, four hundred bucks." Bill's eyes lit up. "When's the party?"
