The final confrontation is chilling, with Elin barely escaping alive as the sanatorium collapses around them. What makes the ending so gripping is how it ties together the themes of trauma and isolation. The eerie setting mirrors the characters' psychological unraveling.

'The Sanatorium' is set in the Swiss Alps, specifically in an isolated, converted sanatorium that's now a luxury hotel. The setting is chillingly atmospheric—snowstorms cut off access, the building's medical history seeps into every corridor, and the surrounding mountains create a claustrophobic tension. The author, Sarah Pearse, uses the location brilliantly; the alpine environment isn't just backdrop but a character itself. Avalanches threaten, the architecture hides secrets, and the echoes of tuberculosis patients from the past blur with present-day horrors. The Swiss setting amplifies the eerie vibe, making the hotel feel like a gilded prison. What's clever is how Pearse contrasts the sleek modern interiors with the building's grim history. The snowy peaks aren't postcard-perfect but ominous, trapping guests with no escape. The altitude plays a role too—characters get headaches, the thin air messes with their judgment, and the isolation feels suffocating. It's a masterclass in using setting to amplify psychological dread.
