Molly crouched behind the hedge, binoculars pressed against her eyes, watching six-year-olds bounce on a inflatable castle. She scratched her chin thoughtfully. "The piñata is a decoy," she whispered. Bill looked up from his hand-drawn diagram. "What?" "The piñata. It's designed to distract us." "Molly, it's a donkey made of paper mache." "Exactly what they want you to think." She snatched the diagram from his hands and circled the area marked presents. "We go in through the bouncy castle, blend with the children, grab the goods." Bill stared at her. "We are both forty-three years old." "Hats," she said, producing two tiny birthday hats from her jacket. "Nobody questions a hat." Bill placed the elastic band under his chin and immediately felt his dignity leave his body entirely. A passing dog barked at him. "The real problem," Molly continued, completely unbothered, "is the clown. He sees everything." "Why are we doing this again?" "Because Gerald from accounting got a much better present than us at the office party and this is technically his nephew's birthday." Bill considered this for a long moment. "Fair enough," he said. "Give me a hat."
