Molly crouched behind the hydrangeas, studying the suburban battlefield with the concentration of a jewel thief and the expression of someone who’d just sat on a juice box. Beyond the fence, a children’s party raged in full sugary bloom: balloons bobbed like surveillance drones, a hired magician produced scarves with criminal confidence, and a clown the size of a wardrobe patrolled the gift table. Bill adjusted his black turtleneck, which in daylight made him look less master criminal and more unemployed mime. He opened a notebook labeled Operation Present Panic and frowned at the crayon map. “Clown’s a problem,” Molly whispered. “Everything’s a problem,” Bill whispered back. “There’s a pony.” Indeed there was. A small, judgmental pony stood beside the patio, wearing a pink ribbon and the eyes of an ex-detective. The presents sat in a glorious heap beneath a banner reading HAPPY 6TH BIRTHDAY EMMA, shimmering with tape and possibility. Molly imagined the haul: action figures, dolls, suspiciously expensive electronics from competitive godparents. A shriek went up as three children cannonballed into a paddling pool. Bill flinched like artillery had opened fire. From the yard came the amplified voice of the magician: for my next trick, who wants cake? Molly grinned. Chaos, she knew, was the master key.
