The Sanatorium

EVERYONES IN DANGER. ANYONE COULD BE NEXT.
An imposing, isolated hotel, high up in the Swiss Alps, is the last place Elin Warner wants to be. But shes taken time off from her job as a detective, so when she receives an invitation out of the blue to celebrate her estranged brothers recent engagement, she has no choice but to accept.
Arriving in the midst of a threatening storm, Elin immediately feels on edge. Though its beautiful, something about the hotel, recently converted from an abandoned sanatorium, makes her nervous - as does her brother, Isaac.
And when they wake the following morning to discover his fiancee Laure has vanished without a trace, Elins unease grows. With the storm cutting off access to and from the hotel, the longer Laure stays missing, the more the remaining guests start to panic.
But no-one has realized yet that another woman has gone missing. And shes the only one who could have warned them just how much danger theyre all in . . .
