The van idled behind the community hall, headlights off, its engine coughing like a grandmother at a jazz club. Molly spread the blueprints across the dashboard. "Forty-two presents, one unguarded cake," she whispered. "Easy." Bill squinted at the banner glowing over the entrance: HAPPY SEVENTH BIRTHDAY, OLIVER! He adjusted his ski mask, which had a cartoon duck printed on the forehead. "Why the duck?" "Camouflage," he said. "Ducks blend in." Molly sighed and slipped on a pair of tiny sunglasses. They crept through the kitchen door without incident, past a stack of paper plates and a punch bowl the color of radioactive lemonade. Inside, a clown was honking a horn at a screaming toddler. Bill froze as a sheet cake wobbled dangerously on the counter. Molly grabbed his sleeve before he could sneeze. "Relax. Nobody suspects a duck."
