Molly spread the blueprint across the hood of the car, weighing down the corners with a juice box, a half-eaten granola bar, and Bill's left hand. "That's not a blueprint," Bill said. "That's a placemat from Denny's." "It's a tactical rendering." She had drawn the Hendersons' backyard in crayon, which she felt showed commitment to the theme. "The party's Saturday. Two o'clock. Thirty kids, one bounce house, and a pile of presents stacked by the patio table like a dragon's hoard." Bill squinted. "We're robbing a six-year-old." "We're redistributing wealth from a child who already has a trampoline." The plan, as Molly outlined it, was elegant in its stupidity. Molly had named the operation Party Foul and printed business cards to prove it. They would arrive dressed as the entertainment. Bill would be a clown. Molly would be the balloon artist, which required no actual balloon artistry, because no adult at a children's party ever makes eye contact with the help. At exactly 2:40, during the piñata, while every parent filmed the blindfolded battering of a paper donkey, they would sweep the gift table into a bounce-house tarp, bundle it like Santa's sack, and walk it out the side gate. "Why do I have to be the clown?" Bill asked, holding the wig at arm's length. "Because you have the face for it." "What's that supposed to mean?" "Nothing. It's a compliment in clown." Bill had concerns. He listed them on his fingers. The bounce house would be full of children. Children, in his experience, were sticky and fearless. Also, the clown shoes did not fit, and also, morally— "Morally what?" "I had a birthday party when I was six," Bill said. "A magician stole my watch." "That wasn't a magician, that was your uncle Gary, and this is exactly why you need closure." "What about witnesses?" Bill asked. "They are six. Their testimony will not hold up in court." Saturday arrived with the clean blue sky of a nature documentary. The costume had been rented from a shop that also serviced funerals, and it showed. Bill's wig smelled faintly of mothballs and regret. Molly, in a vest of un-inflated balloons, cased the yard through the fence slats. The gift pile was magnificent, three feet high and glinting with ribbon. One box was unmistakably a bicycle-shaped bicycle wrapped in paper that did nothing to disguise it. "We could just take the bike," Bill whispered. "We take everything or we take nothing. A heist has principles." They rang the doorbell at 1:58. Mrs. Henderson opened it, took in the clown and the balloon artist, and checked her phone with the haunted expression of a woman who had definitely hired a magician. "You must be the entertainment," she said, in the tone of a question with no safe answer. "We must be," said Molly, and swept inside before the universe could correct her. Behind them, thirty children screamed in a harmony only sugar can produce. Somewhere deep in the house, a piñata waited to die.
