Hannah is determined to start a new life after her failed marriage, and so moves to Edinburgh and begins a job as a guide to the spooky tourist attraction, Henderson Close. She loves it; the tales she recites, the character she plays, and the disquiet she brings to her guests. All is not as it seems however, as Hannah and her two colleagues soon experience strange occurrences they can't explain.
Karen Lewis is surprised to receive a call from her estranged brother's partner, especially when said brother disappeared some time ago. Eager to learn more of his life, and perhaps even gain insight into his whereabouts, Karen agrees to visit the bed and breakfast she's apparently now partly in ownership of. If the rural town of Fallen Trees wasn't remote enough, the odd business her sibling was working on is even more isolated, and something within it seems restless.
