The rain drummed on the van roof as Molly squinted through binoculars at the Hendersons' backyard, where a bouncy castle glowed like a bribe. Thirty children shrieked inside its vinyl walls, and somewhere a clown honked a horn with the enthusiasm of a man who had surrendered his dignity years ago. Beside her, Bill licked frosting off his thumb. He had swiped a cupcake from the buffet on the way back, and the wrapper sat crumpled in his lap like evidence. "Focus," Molly hissed. "Grandmother with the whistle, remember?" Bill nodded gravely. "How could I forget? That whistle haunts my dreams." The plan was simple, at least on paper. Slip through the side gate during the piƱata swing, hit the gift table while everyone screamed about candy, then vanish before anyone noticed the mountain of wrapped boxes had shrunk. Molly had rehearsed the route three times in her head. She had even drawn a diagram on a napkin, which now doubled as a sticky smear across the dashboard. Across the lawn, a dog barked. Bill froze, cupcake halfway to his mouth. Molly grabbed the back of his collar. "Not the dog," she whispered. "Anything but the dog."
