Molly adjusted her binoculars and peered through the hedge at the birthday party. Bill crouched beside her, holding a bag of sandwiches. "Bouncy castle's the problem," Molly whispered. "Forty children, one clown, and a mountain of presents." "I'm not afraid of a clown," Bill said. "You fainted at the last one." "That was a mime. Different thing entirely. Mimes are unsettling." Molly sighed and unrolled a crude map drawn on a napkin. "Here's the plan. You go in dressed as the pizza guy. Distract the parents. I'll slip in through the garden, swap the presents with these identical empty boxes, and we're gone in ninety seconds." "Why do we have empty boxes?" "Because I'm a professional, Bill." He examined one. "This one says 'Happy Retirement.'" "We're working with a budget." A shriek erupted from the party. A child in a dinosaur costume sprinted past, chased by three others. "Also," Bill said, "what if the kids catch us?" "Then we bribe them with cake. Never negotiate with a child holding a sugar advantage." Bill nodded solemnly and pulled a pizza hat from his bag. It read Gino's. Molly grinned, tightened her gloves, and whispered, "Let's go ruin a birthday."
