Molly spread the blueprints across the hood of the van, which were actually place mats from a pancake restaurant. "That's the bouncy castle," she said, tapping a syrup stain. "We go in through the inflatable drawbridge at fourteen hundred hours." "Two o'clock is cake," Bill said. "Nobody watches the gift table during cake. It's a sacred window." "How long?" "Four minutes. Maybe six if the mother insists on candles and a song." Molly nodded slowly. "And the clown?" "Bingo the Unhinged." Bill lowered his voice. "He does balloon animals with genuine menace. If he makes you a giraffe, you take the giraffe, Molly. You thank him." "I'm not afraid of a clown." "You should be. He remembers faces." "I'll wear the bunny costume." "There's already a bunny. Cousin Derek. He's paid." "Then Derek gets a nap," Molly said, sliding on her sunglasses. Bill sighed and looked at the bulging pile of wrapping paper visible through the garden gate, glittering like treasure in a dragon's cave. "Some of that's clothes," he warned. "Socks. Educational puzzles." "We take everything. We sort later, like professionals." "And the birthday boy?" Molly paused, one hand on the door handle, her jaw tightening with terrible resolve. "He's seven, Bill. He'll learn."
