"Right, so the party starts at two," Molly said, spreading a crayon-drawn map across the dashboard. "We go in through the back door, past the bouncy castle." "A bouncy castle," Bill repeated. "That's basically a security system, Molly. You can't sneak across a bouncy castle." "Which is why we go around it, Bill. Stay focused." "And the presents?" "Stacked on a folding table near the kitchen. Classic suburban layout. We grab, we bag, we vanish." "What about the parents?" "Distracted. There's a magician booked for two-fifteen. Every adult eye will be on Trevor the Tremendous." "You know the magician's name?" "I did reconnaissance, Bill. That's called professionalism." "You went to a child's birthday party alone and took notes." "I blended in. I brought a casserole." Bill stared at her. "What kind?" "Tuna. Focus. We've got a fourteen-minute window while Trevor does his dove routine. In and out." "What if a kid sees us?" "We tell them we're Santa's helpers doing an early pickup." "It's July, Molly." "Kids are stupid, Bill. That's why they still get presents instead of cash." Bill sighed and started the engine.
