Molly unrolled the blueprint across the table. "Okay, Bill, talk me through it." "Simple. We roll up in the clown car at fourteen hundred hours." "A clown car?" "Nobody suspects a clown, Molly. It's criminology 101." "That's not a real thing." "It should be. Anyway, I distract the kids with balloon animals while you load the loot into the trunk." "You can't make balloon animals." "I can make a snake." "A snake is just a balloon, Bill." "It's a balloon with *intent*." She pinched the bridge of her nose. "What about the parents?" "Piñata." "What about the piñata?" "No, I mean we hit the piñata. Chaos. Candy everywhere. Kids lose their minds. Parents are knee-deep in toddlers. We walk out with a sack of presents like Santa in July." "And the birthday boy?" "Tommy? Seven years old. Weak. Tiny. Cake-drunk." "Bill, we are not fighting a child." "I'm not fighting him, I'm *outmaneuvering* him." "He's seven." "And I'm thirty-eight, Molly, which means I have thirty-one years of life experience on him. Advantage: us." She sighed. "Fine. But I'm driving the clown car." "Obviously. I can't see out of these shoes."
