Molly and Bill crouched behind the privet hedge of number twelve, where balloons bobbed above the garden fence like brightly colored surveillance devices. A plastic banner announced HAPPY 7th BIRTHDAY ELSIE in letters so cheerful they felt accusatory. Beyond the gate came the shriek of children, the squeak of hired entertainers, and the damp thud of a bouncy castle giving up on physics. Molly adjusted her black gloves with the solemnity of a concert pianist. Bill, beside her, wore a caterer’s jacket he had acquired under circumstances he described as “morally freelance.” It still had a gravy stain shaped uncannily like Norfolk. “This,” said Molly, peering through the hedge, “is either the easiest score of our careers or the exact moment karma finally gets organized.” Bill sniffed. “I don’t believe in karma. I believe in distracted parents and poor gift-table security.” On the lawn, a clown in a waistcoat the color of emergency vehicles produced bubbles while half a dozen children stamped on them with ecstatic malice. Near the patio doors stood the target: a long table piled with presents in glossy paper, ribbons, gift bags, and one enormous stuffed giraffe wearing a bow tie. Bill’s eyes shone. “Look at that. It’s like Christmas robbed a toyshop.” “Focus,” Molly said. “Entry through the side gate. Blend with the vendors. Seize the parcels. Exit via the alley before anyone notices the giraffe has changed hands.” Bill frowned. “You’re assuming I want the giraffe.” “You always want the biggest useless object in the room. It’s why we own a grandfather clock that doesn’t tell the time.” “It tells a time,” Bill muttered. Molly pushed open the gate a fraction. The smell of sausage rolls and sugar hit them like an edible fog. Adults clustered near folding tables with paper plates, all engaged in the universal parental sport of pretending this was relaxing. A magician was setting up by the fence, producing from a suitcase an improbable number of scarves. “Right,” Bill said. “I go in carrying the tray, you drift toward the presents, and if challenged, we say we’re with the entertainment.” “We are the entertainment,” Molly said. “Petty larceny with a family-friendly tone.” They slipped inside. Bill straightened instantly, adopting the weary briskness of service staff everywhere. He picked up an abandoned tray of iced cupcakes and navigated through the crowd with surprising dignity. Molly moved after him, smiling the vague smile of a woman who definitely belonged somewhere. A little boy in a paper crown blocked her path. “Are you the pirate?” “No,” said Molly. “Management.” He nodded, satisfied, and ran off screaming about treasure. Bill reached the gift table and set down the tray. “Phase one complete,” he murmured. “I’ve infiltrated the sponge cake perimeter.” Molly joined him. Up close, the haul was magnificent: boxes with rattles, parcels with suspiciously expensive dimensions, and enough tissue paper to insulate a cathedral. “Take the bags first,” she said. “Less rustle.” Bill lifted three at once. “Who gives a child this many presents?” “Grandparents with guilt. Quick.” From the patio, a mother’s voice rang out. “Has anyone seen the cupcake man?” Bill froze. “I’ve been promoted too quickly.” “Keep moving,” Molly hissed. They sidled along the fence, burdened now with bags and parcels. The stuffed giraffe loomed behind them, judgmental. Bill glanced back. “I’m just saying, it would be rude to leave him.” Before Molly could object, the clown turned and pointed directly at them. For one breathless moment she thought they were finished. Then he honked his red nose and shouted, “Look, kids! The present fairies!” Twenty children erupted in applause. Molly’s expression didn’t change. “Bill.” “Yes?” “We are leaving immediately and never speaking of the title ‘present fairies’ again.” Bill hoisted the giraffe under one arm as they slipped through the gate. “Agreed,” he said, grinning. “Though I must admit, it’s the cleanest exit we’ve ever had.”
