“You brought a sack?” Molly whispered. “I brought two,” Bill whispered back. “One for presents, one for—” “More presents?” “Sandwiches. I get nervous.” They crouched behind a hedge outside the community hall, where a banner announced FINN’S SEVENTH BIRTHDAY in letters shaped like dinosaurs. Through the windows, brightly wrapped gifts crowded a table. Molly eyed them with the grave concentration of a jewel thief assessing a crown. “Every present,” she said. “In and out. No fuss.” “Define fuss.” “Anything involving sirens, screaming, or a clown.” Bill glanced at the inflatable clown by the door. “What if it starts it?” “Then we’re allowed to defend ourselves with dignity.” “I left my dignity in the car.” “Then use the sandwiches.” Bill looked down at his sack. “I packed egg salad.” “Terrifying. Let’s go.” They entered through the hall’s open front door, which Molly had expected to be locked. She paused on the mat. “That was suspiciously easy.” “Maybe they’re expecting us.” “Why would a seven-year-old expect two burglars?” “Maybe Finn’s very worldly.” Inside, children shrieked happily around a cake shaped like a volcano. The adults were busy lighting candles. Molly and Bill stood in the doorway, each holding a sack. A woman with a party hat spotted them. “You must be the entertainers!” Molly smiled nervously. “We’re… a surprise.” “Excellent,” said the woman. “The children have been waiting for the magician.” “We’re not magicians,” Bill said. Molly nudged him. “We’re mysterious.” “Can you make a rabbit appear?” the woman asked. “Certainly,” said Molly. Bill leaned close. “Can we?” “Not if you keep asking.” The woman waved them toward the gift table. “Put your props there, please.” They stared at the presents. Bill murmured, “This is a gift.” “Don’t be stupid.” “I’m just saying, we’re being directed to the loot.” “Props,” Molly whispered. “Maybe the loot is props.” “Your optimism is a public danger.” They set down their sacks. A little boy approached, holding a paper crown. “Are you the magician?” Molly crouched. “We can do one trick.” Bill produced an egg-salad sandwich from his coat. The boy gasped. “You made lunch!” “Not exactly,” Bill said. Molly snatched the sandwich away. “For my next trick, I’ll make this disappear.” “Can you make my present disappear?” the boy asked. “It’s socks.” Molly looked at the gift table, then at the children’s hopeful faces. “We’re not stealing presents.” Bill sighed. “You say that now, but you haven’t seen the socks.” The birthday song began. Everyone joined in except Bill, who was quietly tying his empty sacks shut. When Finn blew out the candles, the children cheered. Molly clapped, and Bill did too, though he looked confused by the cake’s erupting paper volcano. The woman in the party hat handed them each a slice. “Wonderful show.” “We didn’t do a show,” Molly said. “Exactly,” Bill replied. “Very advanced.” Outside, Molly inspected the empty sacks. “Worst heist ever.” “Best cake ever.” “Next time, we steal something sensible.” “Like what?” “Your sandwich.” Bill clutched his coat. “You’ll have to get past the clown.” The inflatable clown toppled gently into the hedge. Molly nodded. “He was expecting us.”
