Rain pattered the car roof as Molly squared her shoulders, eyeing the house across the street. Halloween-party streamers fluttered from the porch, but the front yard pulsed with colored balloons and the high tinny wail of a bounce house. "Forty-seven presents," Bill murmured, tapping his phone screen. "Half of them look like Legos. The other half… glitter. Real glitter, the kind that stains." Molly snorted, adjusting her wool scarf against the damp. "You sure about the guest list? I saw a mom with a clip-on microphone yelling, ‘No tracking dirt on the cupcake table—mini disasters, not mini cupcakes.’" Bill snickered, popping a lollipop into his mouth. "Kid whose mom makes him wear sparkly shoes? Probably doesn’t notice her $400 Moncler getting splashed with Kool-Aid." Molly leaned back, grinning, rain beading on her window. "Fine. But if we get caught, I’m blaming the balloon animal guy. He kept winking—said my crocs are cool for a heist." Bill tossed her a rusted crowbar. "Deal. Now let’s make those moonbeam curtains very wet."
