Molly peered over the blueprints, her brow furrowed in concentration. "Alright, Bill, let's go over the plan one more time. We need to get in, grab the goods, and get out without a hitch." Bill nodded, his eyes gleaming with mischief. "I've got it all figured out. We'll scale the wall, slide through the air vents, and be in and out before anyone even knows we're there." "And what about the security system?" Molly asked, tapping the schematics. "They've got motion sensors and cameras all over the place." "Leave that to me," Bill said, a sly grin spreading across his face. "I've got a few tricks up my sleeve." The two thieves pored over the details, their voices hushed as they mapped out their plan of attack. Molly chewed on her lip, her mind racing with contingencies and escape routes. "What if someone sees us?" she asked, her hands trembling slightly. Bill reached out and gave her shoulder a reassuring squeeze. "Don't worry, Molly. I've got this all under control. We're going to be rich beyond our wildest dreams by the time this is over." Molly took a deep breath and nodded. "Alright, let's do this." The night of the heist, Molly and Bill crept through the shadows, their movements silent and precise. They scaled the wall with ease, their fingers finding every crack and crevice. "Ready?" Bill whispered. Molly nodded, her heart pounding in her chest. "Ready." They slipped through the air vents, their bodies contorting to fit the narrow space. Molly could feel the sweat beading on her forehead, but she pushed on, focused on the task at hand. "There," Bill said, pointing to a vent cover below them. "That's our way in." Molly peered down, her eyes widening at the sight of the brightly colored balloons and the sound of laughter echoing from the room below. "This is it," she said, her voice barely above a whisper. Bill grinned and began unscrewing the vent cover. "Let's do this." Molly held her breath as they lowered themselves into the room, their feet touching down on the carpeted floor. They crept along the perimeter, their eyes scanning the room for their target. "There," Molly whispered, pointing to a pile of beautifully wrapped presents. Bill nodded, his expression intense. "Let's get to work." They moved quickly, their hands deftly unwrapping the presents and stuffing the loot into their bags. Molly couldn't help but feel a twinge of guilt as she watched the children's faces light up with joy, but she pushed the feeling aside, focused on the task at hand. "Hurry up," Bill hissed, his eyes darting around the room. Molly nodded and redoubled her efforts, her fingers moving with lightning speed. They were so close, she could practically taste the riches that awaited them. But just as they were about to make their escape, a small voice rang out from across the room. "What are you doing?" Molly and Bill froze, their hearts pounding in their chests. They turned slowly, their faces etched with terror, to find a young boy staring at them, his eyes wide with confusion. "Uh, nothing," Bill stammered, trying to hide the bag of stolen goods behind his back. The boy's brow furrowed. "Those are my presents." Molly and Bill exchanged a glance, their faces pale. They knew they were trapped, and there was no way out.
