Molly crouched behind the hydrangeas, binoculars trained on the Hendersons' backyard, where forty screaming six-year-olds orbited a bouncy castle shaped like a unicorn's head. Bill wheezed beside her, wearing a foam banana costume he insisted was tactical. The presents sat on a folding table beneath a banner reading HAPPY 6TH BIRTHDAY, CHESTER! A clown hovered nearby, eating a cupcake with the grim focus of a bodyguard. Molly lowered the binoculars slowly, gravely. "Clown's a problem." Bill adjusted his banana peel. "He'll be easy to distract." "With what?" Bill produced a single balloon animal, slightly deflated, that vaguely resembled a giraffe or possibly a tragedy. Molly stared at it for a long moment, then pinched the bridge of her nose. Somewhere a piƱata met its violent end, and the children roared in primal delight. She had cracked vaults in Zurich. She had once stolen a racehorse using only a sandwich. Now her career hinged on a man dressed as fruit and a mob of sugar-crazed toddlers who, frankly, looked more organized than her crew. "Fine," she muttered at last, pulling on her stocking mask. It smelled faintly of stale juice boxes. "But if a unicorn arrests us, I'm blaming you."
