Molly adjusted her birthday-party disguise. “Bill, are you sure this is our best plan?” “Absolutely,” Bill whispered. “We enter disguised as entertainers, locate the present table, and leave with everything before anyone notices.” “Everything?” “Every wrapped box,” he said. “The ones first.” Molly glanced through the hedge. “There’s a clown, a magician, and twelve children armed with frosting.” “Children are observant,” Bill admitted. “But they respect authority. I’ll be Captain Giftgrabber, you be Lieutenant Ribbon.” “Those ranks sound invented.” “They’re invented.” A balloon popped. Molly flinched. “What if we get caught?” “We improvise. If challenged, announce an emergency present inspection.” “By whom?” “The International Society of Present Inspectors.” “That’s not real.” “Neither is your mustache,” Bill replied. “Yet children believe it.” Molly touched the mustache. “It’s shedding.” “Then call it festive.” They crept toward the gate. A girl opened it. “Are you the thieves?” Bill froze. “We prefer ‘temporary gift relocators.’” “You can’t steal our presents,” she said. “They’re for the shelter nearby.” Molly removed her mustache. “Bill, new plan?” “Absolutely,” he said. “We steal the clown’s cake, deliver the presents, and accept payment in frosting.” The children cheered.
