The first part of this horror story about a series of identical houses is told in a series of emails received from Mark Condry, who has received a newspaper clipping in the mail describing a double murder and suicide committed by an old friend, Andrew. Mark decides to investigate, but disappears after sending a series of text messages from a house that may have changed Andrew completely. The second section of the story is told in a series of "updates" on the website with links to various blogs, with extensively interlinking comments.
