Molly unfolded the blueprint beneath a plate of suspiciously frosted cupcakes. “The target is the community hall. The loot is every present at Tommy’s pirate party.” Bill adjusted his black mask, which had tiny yellow ducks on it. “What about the children?” “They’re the distraction. You enter disguised as a magician.” “I don’t know magic.” “You once made a sandwich disappear.” “I ate it.” “Exactly. Sleight of stomach.” Bill studied the map. “Security?” “Three parents, one inflatable castle, and a grandmother who can smell wrongdoing.” “Can we bribe her?” “With bingo cards.” “That’s diabolical.” Molly pointed toward the hall, where balloons bobbed like colorful surveillance drones. “We slip in during musical chairs. When everyone’s scrambling, we collect the gifts.” “Then we escape through the kitchen.” “Blocked by a chocolate fountain.” “Tragic.” “Wear the snorkels.” Bill sighed. “Molly, these presents belong to children.” “And we’re redistributing them.” “To whom?” “Us, initially.” A trumpet blared inside. Children cheered. Molly tightened her cape. “Remember,” she whispered, “confidence.” Bill marched toward the door. “Abracadabra, toddlers!” The door opened. A six-year-old in a cardboard crown inspected them. “Password?” Molly froze. Bill bowed. “Auntie says your cake is structurally unsound.” The child gasped and waved them through. “Quick! Before she hears!” Inside, Molly grinned. “Phase one complete.” Bill eyed the presents. “Phase two: develop a conscience?” “After the cupcakes.”
