Molly spread the crayon-drawn map across the hood of the van and stabbed her finger at a pink rectangle labeled "prezints." "The birthday girl turns six at two o'clock. That gives us exactly forty minutes before they cut the cake." Bill squinted at the map. "Who drew this, a child?" "I drew it, Bill." "Right, so a child." He scratched his chin. "What about the clown?" Molly pulled out a thick folder and flipped it open with professional gravity. The clown's headshot stared back at them. "Giggles McGee. Retired. Bad knees. He won't chase us past the bouncy castle." "And the parents?" "Occupied. Pin the tail on the donkey runs long when adults get competitive." Bill nodded slowly, absorbing the intelligence. A balloon drifted past the windshield on the breeze, and he watched it go with something almost resembling conscience. "These are kids' presents, Molly." "Wrapped, tagged, and totally resellable." "I want it noted I had reservations." "Noted." She handed him a party hat. "Now put this on. We need cover." Bill stretched the elastic under his chin and stared at himself in the mirror. "I look ridiculous." "You look invited."
