Molly tapped the blueprint of Maple Street Community Hall. "Third window, left side. The kids' party starts at four, and the piƱata's full of cash, but the real prize is the gift table." Bill squinted at the diagram, chewing a cold churro. "Presents? Molly, we're thieves, not elves." "Nobody's paying attention to a grown man climbing through a window with a sack. Besides, those toy trains are worth a fortune on the black market." "And the clown?" Bill asked. "He looked like he bites." "He's a sixty-year-old man named Gerald. We'll handle Gerald." Bill sighed and stuffed a rubber duck into his coat pocket, which squeaked loudly. Molly glared. "Subtle." "It's a cover. Nobody suspects the duck." Outside, a bouncy castle groaned in the breeze, and somewhere a toddler wailed about cake. Molly grabbed the crowbar, Bill grabbed the gift bag, and together they crept toward the hall, two grown thieves about to rob a birthday party and questioning every life choice that led them there.
