Molly adjusted her fake mustache while Bill spread out the floor plan on the carpet. The children's birthday party was tomorrow, and they'd finally found their mark: a house full of unopened presents worth thousands. "The presents arrive at noon," Molly said, tapping the diagram. "We go in through the kitchen window while everyone's singing happy birthday." Bill frowned. "Won't they notice two adults crawling through a window?" "Not if you move faster than a three-year-old, which shouldn't be difficult." "Fair point. What about security?" "They hired a clown. His only job is making balloon animals." "A clown?" Bill groaned. "That's somehow worse than actual security." "Exactly. We grab the presents, load the van, and we're gone in eight minutes." Bill studied her face. "You've thought about this way too much." "You say that like it's a bad thing. Besides, I've already cased the place twice." "Of course you have." He rolled up the plans. "When do we start?" Molly grinned. "Tomorrow, right after the piƱata breaks. Everyone will be too distracted eating candy to notice their gifts disappearing." Bill shook his head, laughing despite himself.
