Molly spread the crayon-drawn map across the hood of their rusty van, smoothing out the wrinkles with her palm. The blueprint had cost them two juice boxes and a firm handshake with a kindergartner named Declan. "So the bouncy castle is here," she said, tapping a lumpy purple shape. "That's our primary obstacle." Bill squinted at the map and turned it sideways. "What's this brown thing?" "A pony. They hired a pony, Bill." He let out a long whistle. "These people aren't messing around." Molly paced beside the van, her sneakers crunching on gravel. She had spent three weeks casing the Henderson house, pretending to be a concerned neighbor interested in their hydrangeas. The presents would be stacked in the garage, unwrapped and ripe for the taking, during the cake-and-ice-cream window. "We go in at two fifteen, right when they sing happy birthday," she said. "Every adult will have their phone out recording. Total blindness." "What about the dog?" "I've got a pound of deli turkey in my fanny pack." Bill grinned and cracked his knuckles. "You beautiful criminal mastermind." "Save the flattery," Molly said, folding the map. "We've got a piƱata-sized window of opportunity."
