“I’m telling you, Bill, this is our biggest opportunity yet.” Bill peered over the garden wall. “It’s a birthday party.” “Exactly. Everyone’s distracted by cake.” “And balloons.” “Balloons are just colorful smoke bombs.” “They are not smoke bombs.” “They could be, with ambition.” Across the lawn, children shrieked around a magician in a purple waistcoat. A table sagged beneath wrapped presents. Molly adjusted her black turtleneck and checked the contents of her satchel: lockpicks, gloves, a cucumber sandwich, and one extremely suspicious-looking rubber chicken. Bill glanced at it. “Why did you bring that?” “Disguise.” “For whom?” “For the chicken.” The magician produced a rabbit. The children applauded. Bill winced. “Our target is the present table,” Molly whispered. “We enter through the side gate, blend with the guests, collect the loot, and exit through the conservatory.” “How do we blend in?” Molly pulled two paper hats from her pocket. One said HAPPY BIRTHDAY. The other said I’M THE BIRTHDAY BOY. Bill stared at the second hat. “I’m not wearing that.” “You’re taller. It makes sense.” “I am forty-three.” “Children are notoriously bad at estimating age.” “They’re also observant.” “Then act natural.” Bill put on the hat. “I feel ridiculous.” “You’re a man in a birthday hat hiding behind a hydrangea.” “I felt ridiculous before the hat.” They slipped through the gate. A little girl blocked their path, clutching a wand. “Are you entertainers?” she asked. Molly crouched. “We’re the surprise.” Bill coughed. “We’re the—” “The surprise,” Molly repeated. The girl narrowed her eyes. “You don’t look surprising.” “That’s our specialty,” said Molly. A boy ran past carrying a plastic sword. “The pirates are in the kitchen!” Bill brightened. “Pirates?” “Party entertainers,” Molly hissed. “I thought you said we were the surprise.” “We’re now rival entertainers. Improvise.” Bill swept off his hat and bowed. “Greetings, tiny citizens. I am Captain Billbeard, terror of the snack table.” The boy gasped. “Can you make a balloon sword?” “Certainly.” Bill grabbed a balloon from a nearby chair. It squealed as he attempted to twist it. Molly watched him produce something resembling a pink, inflated intestine. “Behold,” Bill announced, “the Saber of Mild Discomfort.” The children cheered. Within seconds, five of them surrounded him, demanding balloon weapons. Molly reached the present table. “Excellent work.” “I’m creating a diversion!” “You’re creating a balloon octopus.” “It has tactical value.” She lifted a large blue box. It rattled. “What’s inside?” Bill asked. “Probably something expensive.” A child tugged her sleeve. “That’s my present for Grandma.” Molly froze. “Your present?” “It’s a singing mug.” The box began singing. “Happy birthday to you,” chirped the mug. Every head turned. Bill dropped the balloon octopus. “Run?” “Not yet.” The magician raised an eyebrow. “You two aren’t on my schedule.” Molly smiled brightly. “Surprise?” The magician snapped his fingers. His rabbit bit Bill’s trouser leg. “Fine,” Bill shouted. “We surrender!” The children applauded wildly. Molly sighed as the parents marched them toward the gate. “We’re never stealing from a children’s party again.” Bill looked at the balloon octopus. “Agreed. We’re stealing from the magician.” The rabbit growled. “After we recruit the rabbit,” Molly added.
