Molly unfolded the hand-drawn blueprint across the dashboard and smoothed out the creases with her palm. It smelled faintly of cheese crackers. "The party starts at noon," she said. "We go in at cake time." Bill peered down at the blueprint. Several of the rooms had been labeled with stickers of cartoon dinosaurs. "Where exactly did you get this?" "Made it myself. Now pay attention." "Did you draw these dinosaurs?" "They're landmarks, Bill. Focus." He leaned closer, scratching the back of his neck. Outside, a minivan rolled slowly past with three balloons tied to the antenna. "What's our exit strategy?" he asked. "Through the garden. All gifts go in the laundry bags." Bill shifted uncomfortably in his seat. "These are children's presents, Molly." "Expensive children's presents. The birthday kid's dad is a hedge fund manager." "That does change things slightly." "It changes everything." She tapped the blueprint with authority. "The clown performs at one fifteen. That's our forty-five second window of total chaos." Bill stroked his mustache. He always stroked his mustache when logic was beating him senseless. "Fine," he said. "But I'm not wearing the elf costume." "You're wearing the elf costume."
