Molly and Bill crouched behind the hedge, watching the birthday party, duffel empty, gloves tight, hearts greedy, whispering together loudly. "Bill, forty-three presents? All by the bouncy castle?" "Perfect. We enter during sing-along. The parents ignore us." "What about the clown?" "Distraction. We replace him." "With who?" "Us. But worse." "I'm not wearing shoes." "Jester of greed. Steal in costume." "And the piƱata?" "Explode it." "Arson!" "Atmosphere." "What about the dog?" "Bribe with cake." "Cupcake?" "Fondant." "You plan crimes around dessert." "Snacks are security systems." "And the camera?" "Unicorn suit." "No." "Yes. It hides the bag." "My dignity." "Loot." "You're insane." "Forty-three boxes." "Forty-three boxes." "We need a map." "Cake." "That's not a map." "It is if you cut it." "Cannibal?" "Logistics." "What if a child sees us?" "Birthday fairies." "Fairies?" "Magical thieves." "That makes no sense." "It's children's logic." "And the parents?" "Tired. Denial. Sugar." "Do we have gloves?" "Silly gloves." "I hate this." "Count." "One." "Two." "Three." "Go." "Wait, the presents won't fit." "Then steal less." "You said all." "Yes, all. In waves." "Waves?" "Heist choreography." "Bill, that's dancing with loot." "Exactly. The clown is already nervous." "Why?" "He knows we're terrible." "So we go anyway?" "Yes. Greedy."
