Molly adjusted her tactical turtleneck while scanning the backyard perimeter through binoculars. The target was a suburban paradise currently overrun by sticky toddlers fueled by sugar. Colorful balloons marked the drop zone. Bill crouched beside her behind a neatly trimmed hedge, checking his metal grappling hook. Why he brought climbing gear to a simple birthday bash was a mystery, but Bill always appreciated theatrical flair. The main prize sat unguarded on a plastic folding table. A massive mountain of shiny gifts beckoned to them. Security consisted entirely of distracted parents drinking sparkling water and taking blurry photographs. Approaching from the rear gate offered superb cover from the chaotic bubble machine currently blinding the patio guests. Molly consulted her waterproof blueprints. A rogue unicorn piƱata swinging wildly from an oak tree presented a minor airborne hazard. They needed pinpoint precision to extract the plastic loot without triggering a major toddler tantrum alarm. Complete silence was absolutely paramount. Bill adjusted his dark ski mask. It was sweltering in the July heat but true professionalism mattered deeply. Molly pointed toward the hired entertainment. "Is the clown completely asleep?" "He ate nine vanilla cupcakes." "Then we secure the Legos." "Leave the giant bouncy castle."
