Molly crouched behind the overgrown hedge, peering through binoculars at the balloons bobbing above the backyard fence. The sounds of squealing kids and off-key singing drifted over like a sugar-crazed alarm system. She lowered the binoculars and elbowed Bill, who was fiddling with a comically large pair of pliers. “Remind me why we’re robbing a six-year-old’s birthday party again?” she whispered. Bill grinned, his mustache twitching like it had its own criminal record. “Because little Timmy’s uncle is a tech billionaire who buys presents in bulk, Mol. We’re not stealing toys. We’re stealing unopened MacBooks, limited-edition sneakers, and one of those robot dogs that costs more than my car. It’s basically a charity heist. For us.” Molly rolled her eyes so hard she nearly pulled a muscle. “You said the same thing about the petting zoo. We ended up with a traumatized alpaca in the getaway van.” “That alpaca was a valuable asset,” Bill protested. “Until it spat on the satnav. Look, this time it’s foolproof. We wait till they start musical chairs, slip in through the side gate dressed as the hired magicians, grab the gift table, and vanish before the piñata even hits the ground.” Molly snorted. “Dressed as magicians? Bill, your idea of magic is making my patience disappear. Last time you tried sleight of hand you dropped the diamond necklace into a bowl of punch.” “That was intentional misdirection,” he said, puffing out his chest. “Anyway, I already rented the costumes. Top hats, capes, the works. I even learned a card trick. Pick a card, any card.” “I pick the card where we don’t traumatize thirty sugar-high children by stealing their new bicycles,” Molly muttered. “What’s our exit strategy when the parents notice two grown idiots in cheap velvet trying to wheel a Barbie Dreamhouse out the gate?” Bill tapped his temple. “Smoke bombs. I got the good ones this time, not the ones that smell like burnt hot dogs. We pop two by the bouncy castle, kids think it’s part of the show, we leg it to the van. I’ve got it parked behind the ice-cream truck. Genius, right?” “Genius is not the word I’d use,” Molly said, checking her watch. “The cake’s due in twenty minutes. Once they’re distracted by chocolate frosting we move. But if I see one parent reaching for their phone, we abort. I’m not doing another police lineup. My mugshot still has cake on it from the bakery job.” Bill offered her a high-five that she reluctantly returned. “See? Teamwork. We’ll be in and out faster than Timmy can say ‘Where’s my new drone?’” Molly adjusted her fake mustache, already itching under her nose. “If this goes south, I’m blaming you. And I’m keeping the robot dog.” “Fair,” Bill said, winking. “Just don’t let it follow you home. Those things get clingy.” They shared a final conspiratorial glance as distant laughter swelled and the first notes of “Happy Birthday” began. The thieves slipped toward the gate, capes fluttering like confused bats, ready to ruin the best worst party in neighborhood history.
