Molly spread the blueprints across the sticky diner table, pinning them down with a ketchup bottle and a half-eaten pickle. "The target is a bouncy castle," she said. "Clown arrives at two. We strike at two-fifteen." Bill squinted. "Molly, these are blueprints of a Chuck E. Cheese from 1987." "Details." She tapped the paper. "The presents will be stacked here, by the cake. We go in as entertainment." "What kind of entertainment?" "I'm a magician. You're my rabbit." Bill set down his coffee. "Absolutely not." "You already bought the ears." "I bought them ironically!" Molly pulled a floppy pink ear from her purse and slid it across the table. Bill stared at it the way a man stares at his own obituary. "The birthday boy is turning seven," she continued. "His name is Tyler. His parents are lawyers. His grandmother gave him a Rolex." "For his seventh birthday?" "She's overcompensating. Focus, Bill." He sighed, fitting the ear onto his head with the dignity of a disgraced senator. "And the escape route?" "PiƱata truck. Parked out back, engine running." "We're stealing from children." "We're stealing from children's *parents*," Molly corrected. "Morally, that's practically charity."
