Molly spread the blueprint across the table—a crayon drawing of a house with a lopsided roof and a stick figure labeled "BOUNCY CASTLE." "This is our intel?" Bill asked, squinting. "A five-year-old's art project?" "Timmy's cousin drew it. It's accurate. There's a bounce house, a magician, and approximately forty unsupervised presents." Bill crossed his arms. "We're robbing a birthday party." "We're liberating gifts from a system that gives one child too much stuff." "That's not liberation, Molly, that's larceny." "Semantics." He rubbed his temples. "How do we even get in? There's parents everywhere." "Simple. You're the magician." "I don't know magic." "You know card tricks." "One card trick. And it doesn't even work." "Kids won't know the difference. Disappear a coin, they'll think you're a wizard." Bill sighed. "And you?" "I'm the balloon lady. Big bag, easy exit, presents hidden inside." "Balloons don't hide presents." "They will if I'm holding forty of them and blocking your face." Bill stared at the drawing again, at the crooked bounce house and the pile of triangles meant to be gifts. "This is insane." "This is Tuesday," Molly said, grabbing her balloon bag. "Now go learn a card trick. We've got a three-year-old's birthday to rob."
