"Okay, so the party starts at three," Molly whispered, unrolling a hand-drawn map across the park bench. "Is that a crayon drawing?" Bill asked. "It's a tactical schematic." "It has a smiley sun in the corner." "Focus, Bill. The presents get stacked near the clown." "There's a clown?" "Every kids party has a clown." "And there's cake?" "Obviously." "I don't do clowns, Molly. That's in my contract." "You don't have a contract." "It's a gentleman's agreement then." "With who?" "With myself. I'm very firm on it." Molly pressed her fingers to her temples. "The window of opportunity is twelve minutes, between the cake cutting and the pass-the-parcel." "What if they play musical chairs? I once got trapped in a musical chairs situation for forty minutes." "How?" "I kept winning. Nobody would let me leave." "That's genuinely impressive, Bill." "I know. It haunts me." "We go in through the garden gate, grab the presents, and exit before anyone notices." "And if a kid sees us?" "Tell them you're a helper elf." "It's July." "Elves work year round, Bill." "Do they?" "I have no idea. Now are you in or not?" "I want the Lego sets." "Deal."
