Molly crouched behind a hedge, peering through the kitchen window of the suburban house. Inside, balloons bobbed beneath the ceiling, a hired magician sawed a cardboard rabbit in half, and a mountain of brightly wrapped presents leaned against the wall. “Bill,” she whispered, “I count thirty-two presents.” “Thirty-three,” Bill said. “You’re counting the magician’s suitcase.” “It has a bow on it.” “It also has a rabbit sticking out.” “Could be a very disappointing present.” Molly adjusted her black wool hat. “We enter through the back door, cross the kitchen, seize the presents, and leave before anyone notices.” “Your plan has one flaw.” “Only one?” “We’re wearing clown costumes.” Molly glanced down at her orange trousers and enormous purple shoes. “You said disguises were essential.” “I said we needed to blend in.” “There are forty children inside.” “And we are the only clowns.” “That makes us memorable, not suspicious.” Bill considered this. “What if we pretend to be divorced clowns? People avoid awkward conversations.” A shriek erupted from the house. “Was that a child?” Bill asked. “No, that was the magician. He’s lost the rabbit.” “Excellent. Chaos is our accomplice.” Molly pushed open the back door. It squeaked like a haunted violin. “Subtle,” Bill muttered. “Move.” They slipped into the kitchen, where a cake shaped like a pirate ship occupied the counter. A frosting ocean lapped against marzipan cannons. Bill stopped. “Molly.” “Don’t touch the cake.” “I wasn’t going to touch it.” “You’re holding a plate.” “I was going to observe it closely.” “Observe while walking.” They crept toward the living room. A small boy wearing a paper crown spotted them. “Are you the clowns?” he asked. Bill crouched. “We are highly trained birthday professionals.” “Do a trick.” Molly stepped forward. “Certainly. Bill will disappear.” Bill turned pale. “I will?” “Begin.” The boy watched eagerly. Molly grabbed Bill by the collar and shoved him behind a curtain. “Ta-da,” she announced. “That’s not a trick,” Bill hissed from the folds. “It worked. He can’t see you.” The boy applauded. “Again!” Before Molly could answer, three more children surrounded her. “Make the presents disappear!” Molly glanced at the mountain of gifts. “We can do that.” Bill emerged, tangled in curtain cord. “Molly, perhaps we should reconsider the exact nature of our crime.” “Nonsense. Load the sack.” They began placing presents into Bill’s canvas bag. Each time they lifted one, a child cheered. “Faster!” shouted the paper-crowned boy. “I’m trying,” Bill said, wrestling with a box labeled TO EMILY. “Don’t read the names,” Molly warned. “I’m not. The box is shouting.” A mechanical dinosaur roared inside it. The magician hurried over, rabbit tucked beneath one arm. “What’s happening?” “Interactive entertainment,” Molly said. “Are they stealing the presents?” he asked. “Educationally,” Bill replied. The birthday girl approached, holding a glittering envelope. “You forgot this one.” Molly accepted it, then froze. “Bill.” He looked inside. “It’s a thank-you card.” “For us,” said the girl. “You’re the best clowns ever.” Molly slowly lowered the sack. “We’re not clowns.” Bill removed his enormous purple shoe. “We’re thieves.” The children gasped. “Thieves who return presents,” Molly added quickly. “After carrying them outside,” Bill said. “And before opening them.” “Definitely before opening them.” The children cheered even louder. By the time the parents arrived, every present sat neatly beneath the birthday banner, and Molly and Bill were trapped in the middle of the room, performing an increasingly desperate magic act involving three balloons and a very offended rabbit.
