Molly spread the crayon-drawn map across the hood of the van. "The bouncy castle is here. Presents pile up on the folding table, here, under the piñata." "A piñata," Bill said. "That's a hazard. Blindfolded child swinging a stick." "That's the diversion, Bill. Nobody looks at the table when candy hits the grass." "And the parents?" "Drinking wine out of plastic cups and pretending they like each other. We have eleven minutes." Bill frowned at the map. "What's this squiggle?" "Grandma. She sits by the gate. She'll offer you a butterscotch." "I take it?" "You take it, you thank her, you keep walking. Refuse and she remembers your face forever." "And the clown?" "There's no clown." "There's always a clown." "There's a magician named Marvelous Dennis. He does the linking rings, badly, and he's the only adult who'll be looking our direction." Bill sighed. "So we're stealing from six-year-olds." "We're stealing from a hedge fund manager who bought his son a diamond-studded scooter to spite his ex-wife. The presents are collateral." "Right." Bill straightened his clip-on tie. "And my cover?" "You're Marvelous Dennis's assistant." "I can't do magic, Molly." "Neither can Dennis. Grab the balloons."
