Molly spread a floor plan across the laundromat table, where Bill was ironing a black ski mask with the solemnity of a priest preparing a small funeral. The map was actually a crayon drawing of the community center, annotated with arrows, cupcakes, and one alarming stick figure labeled “security guard.” Bill tapped the party room entrance. “Tonight we enter through the bouncy castle, carrying no weapons,” Molly whispered. “Disguise?” Bill asked. “Clowns, obviously,” Molly said. “I am allergic to joy and paint,” Bill muttered. Their target was a mountain of gifts beneath a banner reading HAPPY BIRTHDAY, NORA, though nobody could explain why Nora had invited thirty children and a magician with a rabbit that looked professionally disappointed. Molly proposed filling pillowcases. Bill proposed a getaway in the party’s rented pony, then remembered neither could ride anything that required confidence. They settled on the fire exit, a handcart, and the principle that no present would be opened until they reached the alley. From inside came shrieks, a kazoo rendition of “Happy Birthday,” and the wet thump of a cake meeting gravity. Bill checked his watch. The party began in four minutes; their six week plan had no clown contingency whatsoever.
