Bill crouched behind the inflatable castle, studying the security camera that was clearly filming in 240p. The children’s party music thumped from inside like a toy drumline. Molly slid a roll of duct tape across her knuckles, whispering calculations in glittery Spanish—mostly invented. She’d already scoped exits: the front door, the back fence, and the mysterious hallway labeled “STAFF ONLY (DO NOT TOUCH BALLOONS).” Bill checked his bag of gadgets: a laser pointer for signaling, a feather for “silent” door-opening, and a present-shaped decoy he hoped would distract the birthday boy long enough for the real haul. Molly nodded toward the buffet table, where frosting sat in bowls as colorful as a crime scene paint palette. “Bill, keep your mask on. Kids notice faces, not excuses.” Bill’s eyes widened at the sound of laughter; a tiny train of toddlers was approaching, escorted by a woman wearing the expression of someone who had memorized every party parent’s name. Bill practiced his stealth face—a grimace that looked like a penguin recalling math. “Got it. I’ll be silent like a mannequin; plan secured.” Molly grinned, pressed the feather against the locked cabinet, and the world held its breath until the latch clicked loudly.
