Molly unfolded the crayon map on the café table, where a sticker dinosaur marked Lily Pepper’s seventh birthday. Bill squinted over cocoa moustache. "That is not a plan," he said. "That is a rainbow having a seizure." "It is intelligence," Molly said. "My niece drew it under contract." "The presents are by a bouncy castle," Bill said. "Children bounce. We don't." Molly set down two paper hats and a wand, all stolen from the café's emergency whimsy basket. "We enter as entertainers," she said. "I entertain nobody." "You made a bailiff cry." "Accounting made him cry." Rain ticked at the window. On the map, Molly circled a square labeled CAKE in red jam. "We distract the magician, charm the grandmothers, ignore the terrier, collect the loot." "The loot has gift tags." "Temporary loot." "From children." "For cake ransom." Bill put on a hat. It split, drooping over one eye like festive seaweed. Molly nodded gravely. "Perfect. You look innocent." "I look concussed." "If anyone asks for a balloon animal, make a worm." "All balloon animals are worms." "Exactly. Confidence." "Bring the extremely large pockets," Molly said softly. Bill saluted bravely with his teaspoon. Molly pocketed the map, smelling buttercream and disaster.
