Molly adjusted her balloon-animal-shaped earpiece and peered through the hedge at the birthday party. Eight-year-olds swarmed the lawn like tiny, sticky locusts. "Okay," she whispered. "The presents are on the table by the bouncy castle. Forty-two of them." "Forty-three," Bill said, lowering his binoculars. "Someone just arrived with a giant llama-shaped one." "Why would anyone buy a llama-shaped gift?" "It's a piƱata, Molly. Which means candy. Which means children with weaponized sugar." Molly shuddered. "Fine. We go in as entertainers. I'm the clown, you're the magician." "I can't do magic." "You don't need to. You just need to make forty-three presents disappear." Bill frowned. "That's literally magic." "It's theft with jazz hands." A boy in a dinosaur costume wandered toward the hedge and stared at them. Molly froze. Bill slowly held up a coin. "Look," he said. "It's gone." He hadn't actually hidden it. The boy pointed at Bill's sleeve. "It's right there." "Tough crowd," Bill muttered. "Abort?" Molly asked. The boy leaned closer. "I'll keep quiet for cake." Molly sighed. "Nobody tell the crew we got outnegotiated by a stegosaurus."
