The two thieves had been planning this unusual caper for days, knowing that the element of surprise would be on their side in such an unexpected location. Molly stared at the invitation they had stolen from the mailbox. Bill paced back and forth in their small apartment, excitement in his eyes. They were going over the plan for the big score at the children's party down the street. "Do you really think we can pull this off without getting caught?" Molly asked doubtfully. Bill stopped and looked at her with a grin. "Of course we can. It's a kids party not fort knox. We go in disguise as entertainers." She frowned at the idea. "What kind of entertainers? I am not wearing that clown nose again after last time." "You make a great clown. I will be the magician and pull the presents out of my hat instead of rabbits," he explained enthusiastically. Molly laughed despite herself. "This is ridiculous but okay. How do we escape with all the gifts?" "During musical chairs we make our move," Bill said. "The kids will be distracted and the parents will be chatting." She nodded slowly. "Fine but we leave one present so it's not too cruel." "Deal," he replied happily. They high fived each other and began to gather their supplies for the evening's adventure.
