Molly spread the hand-drawn map across the park bench, anchoring the corners with her lukewarm coffee cup and Bill's reluctant elbow, which he hadn't offered willingly. "The bounce house is our biggest problem," she said, tapping the wobbly purple rectangle she'd sketched from memory. "It completely blocks the side gate." Bill scratched his chin thoughtfully. "We go in through the front. Bold as anything. Nobody suspects the clown." "You're not a real clown, Bill." "I have the wig." Molly stared at him for a long, uncomfortable moment while a fat pigeon waddled boldly between them, apparently also judging him. "The presents are stacked near the gazebo. Sixty-plus gifts based on the RSVPs I intercepted." "You intercepted a six-year-old's birthday invitations?" "I prefer the technical term reconnaissance." Bill nodded slowly, the way he always did when he was both deeply impressed and mildly horrified. "And what exactly is the exit strategy?" "The bouncy castle." "You said it was a problem." "It's a problem getting in," Molly said, finally smiling. "It's a perfect getaway vehicle heading out." Bill looked at the map, then at Molly, then back at the map. "I'm not sure that's how physics works." "Neither is our entire career."
