Molly spread the blueprint across the kitchen table, a crumpled birthday invitation serving as their only intelligence. Bill leaned over her shoulder, chewing on a stale donut, squinting at the crayon-drawn map of the Hendersons' backyard. "Bounce house is the weak point," Molly muttered, tracing a finger along the fence line. "Nobody guards a bounce house." Bill nodded slowly, though his eyes had drifted toward the pile of wrapped presents illustrated in the corner of the invitation, complete with little exclamation points reading "SO MANY GIFTS!!" They'd cased the place for three days. Six-year-old Tommy's birthday party promised balloon animals, a magician named "The Astounding Reginald," and—most importantly—a mountain of loot from doting relatives who clearly overcompensated for divorce guilt. "Face paint," Bill said suddenly, tapping the plan. "We go in as face painters." Molly considered this. It was either brilliant or the dumbest idea she'd heard all month, possibly both. "Fine," she said. "But I'm not doing balloon animals. Last time I nearly lost a finger." Bill grinned, already reaching for the rainbow wig hanging on their doorknob. Somewhere out there, a six-year-old's birthday was about to become a masterclass in unexpected loss—and a very confusing police report.
