Molly crouched behind the hydrangeas, watching the inflatable castle bob like a sleepy whale. Bill clicked a lockpick between his teeth, as if bravery came in mint flavor. The party music thudded through the night, followed by the squeal of someone discovering glitter. Molly slid a sack from her backpack. “Plan?” Bill nodded toward the bannered doorway. “Enter at face-paint; no questions.” Molly whispered, “Steal everything, quietly.” Bill grinned. “Capes distract. Kazoos fix.” A guard in a superhero cape wandered past, permanently bewildered, while parents handed out cupcakes like tradeable currency. Molly stared at the present pile, each box wearing a tag that practically begged for theft. “Go!” she breathed. Bill paused beside her, adjusting his disguise and speaking softly: “For the kids. Promise.” Molly gave a final shove to the door and added, “Also thanks.” The instant they slipped inside, frosting-scented chaos erupted. Wrapping paper crinkled in anticipation. Molly opened the sack; Bill prepared the kazoo-shaped banana. Tonight, the children would wake up with fewer gifts and more confusing stories. Molly counted to three, then faked a yawn loudly, like a tired birthday fairy. Bill snatched the first box, whose bow popped in a tiny confetti sneeze for luck.
