“A spine-tingling, atmospheric thriller” – Richard Osman
You are invited to The Sanatorium. You won’t want to leave… until you can’t. An imposing, isolated hotel high up in the Swiss alps which was once a Sanatorium plays host to an engagement party. With a threatening storm cutting of access to and from the hotel, things go from bad to worse when the bride-to-be vanishes. And she’s not the first.
