Molly spread the blueprint of the community center across the hood of their van. Bill squinted at the crayon-colored layout. The vault, according to Molly, was the gift table beside the bouncy castle. "You want us to infiltrate a six-year-old's birthday party for loot?" Bill whispered. "It's the biggest score in town. Twenty kids, twenty presents, zero security," Molly replied. "There's a clown. Clowns remember faces," Bill muttered. "We wear disguises. You will be the magician," Molly insisted. "I can't do magic. I can barely shuffle cards," Bill protested. "You just pull a rabbit out and grab the Lego sets," Molly ordered. Bill stared at the entrance marked with balloons. "And if the kids cry?" Bill asked. "Then we run faster," Molly answered. She folded the blueprint and grinned quietly. Bill adjusted his mustache nervously while children screamed inside about cake and frosting. Molly checked her watch and nodded toward the side door guarded only by a very sleepy teenager. "So we crawl through the ball pit during pin the tail?" Bill questioned. "Exactly. Distraction, extraction, celebration. We split the action figures fifty fifty," Molly promised. "And if the birthday boy tackles me hard for all the presents?" Bill worried.
