Molly pressed her nose to the bakery window. “Bill, behold: balloons, cupcakes, and a mountain of presents.” “Those are for children, Molly.” “Tiny aristocrats with frosting on their cheeks. They’ll survive.” “We are jewel thieves, not villains in a bedtime warning.” “Exactly. Nobody expects professionals at a bouncy-castle party.” “I’m not crawling through a tunnel shaped like a caterpillar.” “You said that about the bank’s air duct.” “The bank’s duct didn’t sing when you touched it.” Molly unfolded a napkin map. “Here’s the plan. We arrive as entertainers.” “I refuse to be a clown.” “Fine, you’re a magician.” “I know one trick.” “Stealing watches?” “Making dignity disappear.” “Perfect. While you distract them, I stack the presents in the wagon.” “The wagon with the duck on it?” “It’s called camouflage.” “It’s called evidence with wheels.” A child inside shrieked with joy. Bill winced. “Molly, what if the presents are socks?” “Then we liberate socks.” “What if one is a puppy?” “We return the puppy with interest.” “Interest?” “A bow tie.” Bill sighed. “We could just rob the parents’ coat pockets.” Molly paused. “That is morally superior.” “Barely.” “Bill, we’re growing.” “We’re terrible.” “We’re efficient.” “Fine. But I’m keeping the magician hat.” “Only if it has cake.”
