Molly crouched behind a hedge wearing a pirate hat, because camouflage had been outlawed. Bill carried a sack, lock picks, and an emergency cupcake labeled “for morale.” Across the lawn, a birthday party glittered with streamers, dinosaurs, and frosting. Presents sat beneath a banner reading HAPPY BIRTHDAY, TREVOR, guarded by six-year-olds with accountant-like vigilance. Molly surveyed the yard through opera glasses; Bill used binoculars backward. “Remember, enter through the cake table, grab presents, and vanish.” Bill nodded solemnly, then stepped on a squeaky rubber chicken. Every child froze. A clown stopped juggling; a kazoo shrieked. “After you, Molly; my dignity is hiding beneath those balloons.” Molly sprinted toward the cake, vaulted a chair, and landed in the punch bowl. Bill slipped on a party hat and crashed into the presents. Wrapping paper exploded. Children cheered, assuming it was entertainment. The thieves scrambled up, arms full of gifts, while Trevor’s mother applauded their interactive routine. Molly bowed. Bill collided with the clown and emerged wearing enormous red shoes. They escaped through the shed, leaving the sack and lock picks behind. Inside, they discovered twelve gift bags filled entirely with matching socks.
