Molly squinted through the binoculars at the bouncy castle, watching miniature superheroes leap about like caffeinated rabbits. The suburban backyard was a fortress of streamers and balloons, guarded by wine-drunk parents who couldn't spot a thief if she wore a striped shirt and carried a bag labeled SWAG. Bill crouched beside her behind the hedge, sweating through his knockoff Spider-Man costume. The mask kept sliding down his face, making him look less like a superhero and more like a melting action figure. "This is ridiculous," Bill whispered. "Shut up and adjust your webshooters." The plan was simple. Bill would infiltrate during musical chairs chaos while Molly created a diversion involving the piƱata and several strategically placed firecrackers. They'd identified the present table near the patio door, an absolute treasure trove wrapped in dinosaur paper and topped with enormous bows. What the neighborhood watch newsletter had failed to mention was that little Jayden's seventh birthday included a fully costumed entertainment company, three actual superheroes walking around, and a security camera hidden in the garden gnome. Molly lowered the binoculars and grinned at Bill. "Ready?" Bill sighed, pulled his mask up, and nodded. This was either their dumbest heist yet or their most brilliant.
