Molly spread the blueprints across the hood of the van. They were drawn in crayon. "Where did you get these?" Bill asked, frowning. "The birthday girl's older brother. Cost me two lollipops and a Pokémon card." "Cheap." "It was holographic, Bill." Bill squinted at the page. A purple rectangle sat in the middle, labeled GIFT TABLE, surrounded by angry red scribbles. "What are the scribbles?" "Security. Four grandmothers, one bouncy castle, and a clown named Mister Giggles." Bill paled visibly. He had met clowns before. None of them had been giggly. Molly tapped the crayon map with a pencil, as if that made it more official. "The plan is elegant. You go in as a magician and distract the crowd. I slip through the back gate with a laundry sack." "I can't do magic." "You can pull a coin from behind your ear." "That's my coin. I keep it there." "Nobody needs to know." Outside the van, a cheerful balloon bobbed past on the breeze, drifting slowly toward the party like an omen. "Molly," Bill whispered, "what if they ask me to make balloon animals?" She stared at him for a long, grim moment. "Then, Bill, you improvise a snake."
