Molly crouched behind the hedge, binoculars trained on the bouncy castle as it wobbled menacingly in the suburban breeze. Beside her, Bill struggled into a clown costume three sizes too small, the seams screaming in protest with every movement. The afternoon sun glinted off the mountain of brightly wrapped presents stacked beside a folding table laden with juice boxes and a suspiciously lopsided birthday cake. "This is the big one," Bill whispered, adjusting his rubber nose. She lowered the binoculars and shot him a withering glance, the kind reserved for partners who'd previously botched a heist by sneezing into an alarm sensor. The plan was simple, elegant even. Bill would infiltrate as the entertainment, dazzling the seven-year-olds with balloon animals while she slipped through the back garden gate and loaded the loot into the getaway minivan, which she'd cleverly disguised with an ice cream decal. The cake's birthday boy, a tiny tyrant named Timmy, had reportedly received a deluxe robotics kit worth more than Molly's monthly rent. That alone justified the risk. "Remember," she hissed, "stay focused." Bill nodded solemnly, then immediately tripped over his enormous shoes, face-planting into a flowerbed. Molly closed her eyes and questioned every decision that had led her here.
