Molly crouched behind the privet hedge in a pink raincoat with a stuffed rabbit sewn to the hood, peering through a pair of opera glasses she had stolen from an opera singer who had been too busy singing to object. Across the street, number forty-two blazed with balloons, streamers, and the kind of shrieking joy that made professional criminals consider honest work. Bill lay beside her in a cardboard box labeled DELUXE MAGICAL PONY, which had seemed like excellent camouflage until a real pony arrived and tried to befriend him. “Remind me,” Bill whispered, “why are we robbing a six-year-old?” “We are not robbing a six-year-old,” Molly said. “We are liberating surplus parcels from a high-density gift environment.” “That sounds worse.” “It sounds strategic.” Inside the garden, children thundered around a bouncy castle shaped like a dragon. Parents stood in clusters, drinking lemonade and pretending not to hear the sugar-fueled war cries. A table sagged beneath wrapped presents: shiny paper, enormous bows, suspiciously toy-shaped lumps. To Molly, it looked less like a birthday party and more like a poorly guarded vault covered in dinosaurs. Bill shifted, and his cardboard flaps rustled. “Stop moving,” Molly hissed. “There’s an ant in here with opinions.” “Then negotiate.” “I don’t speak ant.” “You speak pigeon.” “That was one summer, and the pigeon lied.” Molly unfolded a napkin on which she had drawn the plan in green crayon. It showed the house, the garden, the present table, and a large arrow marked GO IN WITHOUT LOOKING GUILTY. Beside it, she had added a drawing of Bill smiling. Unfortunately, crayon Bill looked guilty enough to be arrested by a crossing guard. “We enter as entertainers,” Molly said. Bill looked down at his box. “I’m the pony?” “You’re the surprise.” “I don’t like being surprises. People scream.” “That’s the point.” At the gate, a clown with a trumpet was arguing with a father about parking. Molly’s eyes narrowed. Opportunity arrived wearing oversized shoes. She stood, pulled the rabbit hood over her curls, and marched across the street with the brisk confidence of someone who belonged anywhere because questioning her would be exhausting. Bill waddled after her in the pony box, bumping into a wheelie bin, a garden gnome, and finally the gatepost. A little girl with a tiara spotted them first. “Mummy! The rabbit lady brought a horse cupboard!” Molly beamed. “Happy birthday, small citizen.” “It’s my birthday,” said a boy in a cape, appearing beside her. “I’m Archie. Are you the magician?” “I am Molly the Mysterious,” Molly declared. From inside the box, Bill muttered, “And I’m regretting my career choices.” Archie gasped. “The box talks!” “Only when fed cake,” Molly said quickly. They were swept into the garden by applause, curiosity, and one grandmother who seemed prepared to clap for furniture. Molly positioned herself near the present table while Bill shuffled center stage. “For my first trick,” Molly announced, “I shall make this ordinary pony box disappear.” “Do we have to?” Bill whispered. “Yes.” “I’ve got stage fright.” “You’re cardboard.” “I’m cardboard with feelings.” Molly whipped a sparkly scarf from her sleeve and flung it over the box. The children cheered. Bill was supposed to crawl backward under the table, gather the presents into the hidden laundry sack, and escape through the side gate. Instead, he sneezed. The scarf flew off. The box toppled. Bill rolled out wearing a party hat that had stuck to his ear. The garden fell silent. Then Archie shrieked with laughter. “It’s a man pony!” Every child charged. Bill scrambled up, pursued by twenty-seven delighted party guests. Molly watched her plan dissolve into frosting and chaos. A toddler climbed into the laundry sack. Someone handed Bill a balloon sword. The pony, apparently jealous, nudged him into the bouncy dragon. “Molly!” Bill yelled, bouncing helplessly. “I’m being entertained!” “Hold firm!” Molly called, stuffing one present under her coat. It immediately began barking. A mother turned. “Is that a puppy?” Molly froze. The parcel barked again, then licked her chin through a tear in the wrapping. Archie ran over, breathless and delighted. “That’s my best present! His name’s Captain Waffles.” Molly looked at the puppy. Captain Waffles looked back with criminally innocent eyes. Bill bounced past upside down. “Abort?” Molly sighed, pulled the puppy from her coat, and handed him to Archie. “Abort.” Archie hugged Captain Waffles. “Can you do another trick?” Molly glanced at Bill, who was now being crowned King Pony by children armed with cupcakes. She considered the present table, the suspicious parents, the unpaid clown still honking angrily by the curb, and the puppy licking jam from her sleeve. “Yes,” she said. “I shall make two burglars vanish.” She grabbed Bill by the cardboard flap and dragged him toward the gate while the children applauded wildly. Behind them, Captain Waffles barked as if promising not to testify. On the pavement, Bill removed the party hat from his ear. “We stole nothing,” he said. Molly checked her pocket and produced a single jelly bean. “Incorrect.” Bill stared. “That’s our haul?” “It’s purple. High value.” He sighed, accepted it, and split it with her using a lockpick. Then they walked away, chewing thoughtfully, already planning something safer, like a bank.
