Molly crouched behind the privet hedge with the solemn concentration of a jeweler evaluating a cursed diamond. Beyond the garden gate, balloons bobbed over a suburban lawn, paper hats flashed in the afternoon sun, and a clown in oversized shoes wandered past a table stacked with presents like a dragon’s hoard wrapped by an underpaid aunt. Bill lay beside her on the damp grass, peering through binoculars he’d definitely borrowed permanently from a horse-racing enthusiast in Croydon. His wool cap had picked up a leaf, giving him the appearance of a very worried shrub. “That,” Molly whispered, pointing at the gift table, “is the most unsecured wealth I’ve ever seen.” Bill lowered the binoculars. “You once robbed a wedding.” “Yes, and they had cousins standing guard. Armed cousins. With feelings.” A shriek of childish delight erupted from the lawn. A magician had produced a rabbit, or possibly a napkin with ears. The children applauded with the savagery of tiny emperors. Bill frowned. “I still think this is morally complicated.” Molly turned to him. “We are thieves, Bill.” “I know what our business card says.” “We don’t have business cards.” “We should. It would save time during introductions.” Molly sighed. “Listen. We are not stealing from children. We are liberating presents from a system that has already failed them. Half those boxes contain educational puzzles.” “That’s true,” Bill admitted. “Nothing says betrayal like a geometry kit.” She nodded toward the gate. “Now, the clown is our problem.” “The clown is everyone’s problem.” “He’s circling the presents.” Bill put the binoculars back up. “He’s making balloon animals.” “Can he make a balloon lapse in judgment?” “No, but he’s distracted by his own shoes. We can use that.” Molly unfolded a hand-drawn plan from her coat pocket. It was mostly arrows and one tiny sketch of Bill looking confused. “We go in as late guests. You carry the cake box.” “There is no cake box.” “There will be. I stole one from a bakery dumpster. It smells faintly of ecclesiastical sponge.” Bill looked offended. “You want me to impersonate cake?” “I want you to look purposeful. No one questions a man carrying cardboard.” “I’ve been questioned carrying less.” Molly ignored this. “I’ll approach the gift table, compliment the wrapping, create social trust, then transfer the presents into the laundry sack.” “The one that says ‘Hotel Bristol’?” “Classy, anonymous, absorbent.” Bill rubbed his chin. “And if a child sees us?” “We say we’re the Present Inspectors.” “That won’t work.” “It works on adults.” Inside the garden, a woman in a floral dress appeared with a tray of orange squash. Children swarmed her instantly, a scene not unlike piranhas discovering a mayor. Bill sucked air through his teeth. “That must be the mother. She looks organized.” “Terrifyingly.” “She’s got a whistle.” Molly peered again. “That’s not a mother. That’s a field marshal with bunting.” “So perhaps,” Bill said, “we retreat and rob somewhere less festive. A tax office. A bishop.” “No. Look there. The side gate, half-latched. Access to the patio. And the adults are gathered around the barbecue arguing about charcoal. This is our moment.” Bill hesitated. “What if the clown clocks us?” “Then improvise.” “I don’t improvise well under face paint.” “You won’t be in face paint.” “I might be if things go badly.” Molly rose into a crouch. “Bill, history rewards the bold.” “History also rewards people who don’t get caught nicking Monopoly sets from seven-year-olds.” She offered him the flattened cake box. “Come on. Chin up. Smile like you belong.” Bill took the box with the despair of a man accepting both destiny and food poisoning. “If anyone asks, what’s my name?” “Uncle Peter.” “I hate Uncle Peter already.” “Good. Use that.” They slipped through the side gate just as the clown tripped over a garden molehill and vanished into a rhododendron to the delighted screams of the children. Molly’s eyes gleamed. “Bill,” she murmured, sweeping toward the mountain of gifts, “sometimes the universe commits to a bit.” Bill squared his shoulders and marched after her. “If we survive this,” he said through a fixed smile, “I’m stealing us business cards.”
