Molly crouched behind the hedge, wearing black trousers, a black sweater, and a paper crown that read BIRTHDAY PRINCESS in glittering pink letters. Beside her, Bill adjusted a pair of opera glasses and peered through the leaves at the suburban garden. The party was in full swing. Children ricocheted across the lawn, shrieking around a magician dressed as a suspiciously sweaty rabbit. Parents clustered near the barbecue. At the center of the patio sat a mountain of wrapped presents, guarded by a golden retriever with the solemn expression of a retired police inspector. Bill lowered the glasses. “Target confirmed. Approximately thirty-seven gifts.” “Thirty-eight,” Molly said. “You counted the one shaped like a toilet?” “That is either a toy toilet or a very disappointing family.” Bill consulted the map spread over his knees. It was actually a menu from the local takeaway, but he had drawn arrows on it in gravy. “We enter through the side gate, distract the dog, cross the lawn, and remove the presents one by one.” “Why one by one?” “Because carrying thirty-eight presents at once looks suspicious.” Molly glanced at him. “So does carrying thirty-seven.” Their plan depended on disguises. Molly had dressed as a children’s entertainer, complete with a red foam nose and a suitcase of inflatable animals. Bill was disguised as a delivery driver, although the company logo on his jacket said BELL’S PIES, and he had no pies. He did have a clipboard, which he believed made him invisible. They slipped through the gate just as the magician produced a rabbit from his hat. The rabbit immediately escaped, sprinting beneath a table and causing six children to abandon their cupcakes in pursuit. “Now,” whispered Molly. Bill hurried toward the presents. The dog rose. Molly flung an inflatable giraffe across the grass. The dog bounded after it, barking with professional enthusiasm. Bill grabbed three boxes and tucked them under his arms. A little girl appeared in front of him. “Are you taking those?” Bill froze. “I’m… delivering them.” “To where?” “Somewhere less festive.” Molly arrived, juggling three rubber chickens. “He’s the Present Relocation Officer.” The girl considered this. “Do you have a badge?” Molly slapped a sticker onto Bill’s chest. It read HELLO, MY NAME IS TREVOR. “Excellent,” said the girl, and ran away. They reached the hedge with an armful of gifts when a voice called from the patio. “Wait! You forgot the big one!” Every head turned. The birthday boy was pointing at a box nearly as tall as himself. Molly and Bill stared at the enormous package. Then the dog returned, carrying the inflatable giraffe and wagging its tail. “Honestly,” Bill said, “we can’t leave one behind.” Together they hauled the box toward the hedge. It was heavier than expected, and something inside rattled ominously. Halfway across the lawn, Molly tripped over a skipping rope. The box burst open. A dozen brightly colored balloons erupted into the sky, followed by a card reading, Happy Birthday, Trevor! The children cheered. The parents applauded. Even the magician bowed. Molly brushed grass from her sleeve. “New plan.” Bill watched the balloons drift away. “We become party entertainers?” “Exactly. We steal the applause instead.” By sunset, they had performed three magic tricks, lost a rubber chicken, and been paid in cupcakes. The presents remained untouched, but Molly considered the operation a success. Bill did not. “We made nothing.” She handed him a cupcake with pink frosting. “You made a friend.” The golden retriever placed its head in Bill’s lap. Bill sighed. “Fine. But next time, we rob a library. Books don’t have birthdays.”
