Old Metairie Mystery Book Club - The Sanatorium by Sarah Pearse

Half-hidden by forest and overshadowed by threatening peaks, Le Sommet has always been a sinister place. Once a sanatorium treating tuberculosis patients, it was abandoned years ago and had fallen into disrepair. Long plagued by troubling rumors, it has recently been renovated into a lavish hotel. And an imposing, isolated hotel, high up in the Swiss Alps, is the last place detective Elin Warner wants to be. But having received an invitation out of the blue to celebrate her estranged brother's recent engagement, she had no choice but to accept.
