Nervous silence sat between Molly and Bill as they crouched by the porch. Molly smelled frosting on the wind. Tonight’s target was a house of wrapped gifts, not armed guards. Bill tapped the entry buzzer like it was a game show button. “I’m wearing the mustache you said would look harmless,” Bill murmured. “It’s harmless until you sneeze,” Molly replied, sliding a tiny crowbar into her sleeve. “We’re stealing every present, Bill—every last one.” Bill glanced at the inflatable dinosaur. “Do the kids notice burglars?” “If they notice, we’re ‘party helpers.’ You carry the ribbon cutter, I’ll carry the clipboard of lies.” Bill lifted a fake clipboard. “What does it say?” “‘Checklist: find the biggest box,’” Molly said. “Then we swap our empty tote for their full tote.” Bill whispered, “And the security system?” Molly pointed at the patio speakers. “The song is our alarm. When the chorus hits, move like you’re dancing and never step on Lego.” Bill nodded, then grinned. “Can I practice dancing on the way in?” “No,” Molly said, “you’ll only distract the squirrels watching us.” They slipped through the open door as someone called that presents were ready. Molly and Bill smiled, counting corners quietly.
