Molly spread the hand-drawn map across the sticky diner table, her eyes gleaming with the intensity of someone planning a bank job rather than what was essentially robbing a bunch of seven-year-olds. Bill leaned forward, squinting at her crayon-rendered blueprint of the Henderson residence. The birthday party was scheduled for Saturday at two. Seventeen children. One bouncy castle. A piƱata shaped like a dinosaur that Molly had already marked as a secondary target. Bill traced his finger along the back fence route, mentally calculating the distance from the gate to the gift table on the patio. "We go in during the cake," Molly whispered. He nodded slowly. The cake moment was genius. Every parent would have their phones out, filming their sugar-crazed offspring destroying a sheet cake decorated with cartoon dogs. Nobody would notice two adults casually loading wrapped boxes into oversized shopping bags. "What about the clown?" Molly's jaw tightened. She had forgotten about the clown. Entertainment had been a variable she had not factored into her calculations. Bill pulled out his own notes, scribbled on a napkin. They would need a distraction, something big enough to keep Ronald or Sprinkles or whatever his name was occupied.
