Molly spread the hand-drawn map across the dented hood of the rusted getaway van. Seventeen small crayon circles marked the perimeter of the Hendersons' backyard. "The bouncy castle is our biggest problem," she said, tapping the largest circle. "It blocks the south exit completely." Bill squinted at the map. "What about the clown?" "What about him?" "He's been watching us for twenty minutes." Bill jerked his thumb toward the street corner. "The one with the enormous shoes." Molly glanced over her shoulder. The clown waved cheerfully. She waved back reluctantly and turned away. "He's just a clown, Bill. Focus." She pulled out a laminated schedule. "Cake cutting is at three. Every adult in that yard will be singing Happy Birthday. That's our window." "How many kids are we talking?" "Fourteen. All under seven." "So they'll cry." "Extensively." Bill sighed and chewed his thumbnail, staring at the birthday banner visible above the wooden fence. It read HAPPY 6TH TIMMY in glittering gold letters. "I feel weird about this," he muttered. "You felt weird about the dog shelter job too, and that went perfectly." "We got bitten eleven times." "Perfectly," Molly repeated firmly, rolling up the map.
