Molly unfolded the birthday invitation across the cafe table like a treasure map. Bill squinted at the glittery dinosaur and stirred tea with a licorice stick. Rain polished the windows; inside, their criminal enterprise smelled faintly of cupcakes. The party was at three, next door, and every guest was bringing something wrapped, ribboned, and tempting. Molly tapped the words Magical Princess Bounce Castle, then lowered her voice dramatically. "Bill, masks?" "Already handled, Molly. We go as clowns." "I fear clowns." "Perfect. You'll look authentic." "What about the children?" "We smile, juggle, and avoid eye contact." "I can juggle one thing." "Then juggle yourself." "Stealing presents from children feels low." "They're mystery boxes. Could be socks." "Could be a fire truck." "We'll donate half." "Half a fire truck?" "Fine. We steal only suspiciously adult-shaped parcels." "Like wine?" "Like aunt sweaters." "Do we bring a sack?" "Too obvious. Bring a tote." "With kittens?" "With tax forms. Nobody checks tax forms." "That is sinister." "Thank you." "I feel underdressed." "Wear shame." At that moment a waiter delivered sprinkle-covered muffins. Molly stared, softened, and pocketed the invitation. Bill grinned as frosting touched his nose. Crime, they agreed silently, could wait for warm cake instead.
