When Maggie saw the beautiful linen curtains moving in the Caldwell´s front window, she went on high alert. Her wonderful, friendly neighbors Cady and Josh are away, so who is in their house? The woman who answers the door tells a convincing story. She´s the house-sitter. Just here for a month. An old friend of Cady´s who needed a place to stay. She´s pleasant and warm, and Maggie wanders back to her house thinking she might have made a new friend. But when Sarah closes the door she knows she must do something about Maggie.

And she definitely doesn´t want anybody walking into the house
