Molly crouched behind the hedgerow and studied the target with the intensity of a general surveying a battlefield. The battlefield in question happened to be decorated with inflatable unicorns and a banner reading "Happy 7th Birthday, Chloe!" which somewhat undercut the gravitas of the operation. Bill crawled up beside her, twigs lodged in his hair, mud decorating his best black turtleneck. He had insisted on the turtleneck. Professional standards, he had said. The backyard was a minefield of obstacles. Fourteen sugar-fueled children careened between a bouncy castle and a table stacked with presents. A clown was making balloon animals with the dead-eyed efficiency of someone who had long since abandoned any remaining joy. A golden retriever patrolled the perimeter with surprising vigilance. "The dog worries me," Molly whispered. Bill surveyed the chaos unfolding before them, watching a child cry over a popped balloon while another systematically destroyed the cake. He pulled out a handwritten diagram and frowned deeply at it. "The presents or nothing." Molly adjusted her hat, rolled her shoulders, and exhaled slowly. She had once robbed a casino in Monte Carlo. She had cracked vaults that baffled engineers. She was absolutely terrified of that retriever.
