When Maggie sees the beautiful Venetian blinds moving in the Caldwells' front window, she freezes. Her favorite neighbours Cady and Josh are away, so who is in their house?

The pretty young woman who answers the door tells a convincing story. She's Sarah. 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. Yet she can't help but wonder why Cady never mentioned Sarah.

What Maggie doesn't know is that on the other side of the door, Sarah is starting to panic. No one was meant to see her at 214 Palmer Street...
