Molly crouched behind the hedge, peering through the gaps at the brightly colored balloons tied to the mailbox. A banner reading "Happy 7th Birthday, Timmy!" flapped in the breeze like a taunt. She had cased worse joints, but none had felt quite so morally questionable. The lawn was littered with tiny obstacles, bicycles, jump ropes, and what appeared to be an aggressive goose that had simply decided to attend uninvited. Bill belly-crawled through the grass to join her, getting a face full of dandelion in the process. He was wearing all black, which made him simultaneously professional and absurd given the sunny afternoon setting. A child near the fence pointed directly at them, then turned away, distracted by cake. "Timing?" Molly whispered. "Two minutes," Bill wheezed. The plan was straightforward. Distract the clown, neutralize the piƱata situation, grab the gift table haul, and vanish before the birthday song began. Simple. Clean. Deeply wrong. Molly checked her bag. Bill checked his conscience, found it surprisingly cooperative, and tucked it away. The goose locked eyes with him across the yard with an ancient, knowing stare. This, Bill realized, was going to get complicated.
