Molly squinted through the binoculars at the bouncy castle swaying in the Henderson backyard. "Bill, this is our moment. You see that pile of presents on the picnic table?" "I count at least thirty wrapped boxes. That's a lot of Legos, Molly." "Exactly. Premium merchandise. Now, here's the plan. You're going in as the clown." "I hate being the clown. Last time a kid bit me." "That kid was me, and you deserved it. Focus. You distract them with balloon animals while I load the goods into the van." "What about the parents? There's like eight of them hovering around the juice boxes." "That's where the genius comes in. I've arranged for a very aggressive door-to-door salesman to arrive at exactly two-fifteen selling timeshares in Florida." "That's actually brilliant." "I know. Now, what's your clown name?" "Mister Giggles." "Too cheerful. Try something edgier." "Bonkers the Magnificent?" "Better. Remember, if anyone asks, you're from Happy Times Entertainment." "Is that a real company?" "It will be for the next forty-five minutes. I made business cards." "You're terrifying sometimes." "Thank you, Bill. Now put on your rainbow wig. We steal at two."
