That morning the house was left in it's normal state as it would be when none of the residents are home. Dogs fed and watered in the basement. And I assume the door unlocked, as Dalton says it always is.
But, Mollie didn't follow her usual routine. She wasn't on social media. She didn't answer texts. She didn't show up for work.
How could the house be just right, when Mollie wasn't?
maybe she was getting breakfast with someone prior to going to work?
