"Presents," said Bill. "Wrapped. Ribboned. Untraceable." "It's a seven-year-old's birthday, Bill." "It's a *vault* with a bouncy castle out front." "What's inside the vault, exactly?" "Toys." "Toys." "Molly, do you know what a limited-edition dinosaur goes for? Sealed?" "No, and neither do you." "I know a man." "You know a man who knows a man who sold you a fake Rolex." "That was a learning experience. Look, we go in at three. Face paint, balloon animals, we blend." "You're forty-six." "I'm youthful." "You'll be the only clown with a lower back brace." "The brace *helps*, structurally, when carrying a sack of gifts." "And the parents? Twenty phones, all filming?" "Parents don't look at other adults. They look at their own child, screaming, on a slide." "That's grim." "That's cover." "And the exit?" "Same door. Everyone hugs the clown goodbye. Nobody frisks the clown." "Somebody will absolutely frisk the clown." "Then we're partners in crime *and* misfortune." "Bill." "Molly." "If we do this, we leave the little girl's present." "Which one's hers?" "The one she opens first, obviously. We watch, we wait, we take the rest." "You're softening." "I'm *scheduling*. Three o'clock. Bring the balloons."
