Molly crouched behind the hedge with a notebook balanced on one knee and a juice box in her hand, because she believed in blending in with a target demographic. Beyond the garden fence, balloons bobbed over a suburban lawn like sentries with very poor training. A clown in giant shoes wobbled near a folding table, and a woman wearing a paper crown arranged brightly wrapped presents beneath a banner that read HAPPY 6TH BIRTHDAY, OLIVER!!! with enough exclamation marks to suggest either excitement or structural instability. Bill lay flat beside her in a bush that had not consented to the arrangement. Leaves clung to his cap. One twig was caught in his moustache, giving him the appearance of a woodland creature trying to remember a password. “Tell me again,” Bill whispered, “why we’re robbing a birthday party instead of, say, a bank, where the money is both legal tender and significantly less likely to contain crayons.” “Because,” Molly whispered back, tapping the notebook, “banks expect thieves. Children expect joy. That’s the security gap.” “That is the most sinister sentence I’ve ever heard spoken over apple juice.” “It’s strategic. Also, these juice boxes are excellent.” Bill peered through the hedge. “I count twelve presents. Four medium, three large, five suspiciously light. One of them is definitely socks. We cannot build a reputation stealing socks from a six-year-old.” “We’re not stealing socks,” said Molly. “We’re stealing opportunity. Wrapped opportunity.” “That sounds like socks in a motivational speech.” From the garden came the shriek of children playing a game that involved running in circles and ignoring gravity. Molly studied the layout. “Entry point is the side gate. Distraction is the clown.” Bill turned to her slowly. “I’m sorry. Did you say the distraction is the clown, as in there is already a clown, or the distraction is me becoming a clown? Because one of those is difficult, and the other is spiritually impossible.” “The existing clown. We redirect attention.” “I don’t trust clowns to cooperate with any plan, accidental or otherwise.” “You don’t have to trust him. You just have to respect the chaos.” Bill sighed. “Fine. Walk me through it.” Molly pointed with the juice box straw. “At two-thirty, cake emerges. Every adult migrates toward cameras. Every child migrates toward sugar. During the singing, you slip through the gate, load the presents into the laundry basket stashed by the bins, and retreat to the van.” “And what are you doing while I’m committing grand larceny in a cardigan?” “I’ll be inside the perimeter, posing as a parent.” Bill stared. “Molly, you are wearing a stripy jumper and binoculars.” She lowered the binoculars. “Observational parent.” A pause. Somewhere, a balloon popped, and Bill nearly entered the hedge on a molecular level. “There is one flaw,” he muttered. “Only one? Splendid.” “The children. They move unpredictably. They are short, sticky, and possess the collective awareness of a surveillance state.” Molly considered this. “True. We may require cover identities.” Bill brightened faintly. “Magicians?” “Too visible.” “Petting zoo staff?” “We have no goat.” “I could source a goat.” “In ten minutes?” “A mediocre goat.” Molly snapped the notebook shut. “No livestock. New plan. We infiltrate as entertainers.” Bill closed his eyes. “That is just clown-adjacent.” “Face painter and balloon artist,” she said. “I cannot make a balloon dog.” “You don’t need to. You need to make balloon confusion.” Inside the garden, the mother lifted the cake high while children gathered, chanting Oliver’s name with the menace of a tiny cult. Molly smiled. “That’s our window.” Bill looked at the presents, then at the chanting children, then at Molly’s determined expression. “If I get tackled by a seven-year-old in a pirate hat, I want it noted that this was your idea.” “It usually is,” Molly said, already standing. “Now smile. We’re about to ruin a very nice afternoon.”
