Molly spread the blueprint across the hood of the van, smoothing it flat with the reverence of a surgeon. It was, in fact, a placemat from the Happy Otter Family Diner, upon which she had drawn the Kowalski backyard in ketchup and blue crayon. The bouncy castle was a lopsided rectangle. The present table was a star. Bill studied it while eating a pickle. He had ideas about pickles and about most things, and had spent the morning insisting the clown costume was a tactical necessity rather than a personal fantasy. The wig sat in his lap like a sleeping poodle. "Nobody suspects a clown," he said. "Everybody suspects a clown, Bill." The party started at two. By 2:15, according to Molly's calculations, seventeen children would be hurling themselves into an inflatable structure while their parents drifted toward the cooler, and for roughly nine minutes the present table would stand unguarded, glittering, wrapped in paper thin as a promise. They would need a laundry hamper, two garbage bags, and the will to look a six-year-old in the eye. Bill honked his nose experimentally. Molly closed her eyes and counted to ten, then folded the placemat into her jacket, unspeakably calm, entirely committed.
