Let the Cold Do It

Nine years ago, a young cook froze to death on the terrace of a remote Alpine refuge, and Clare Tait was blamed for logging the callout too late. Now she's taken the winter caretaker's job at that same refuge, two thousand three hundred metres up, where fingernail scratches in an old cellar door frame spell out three words nobody wants read. When the storm cuts the cable car and a guest dies behind a barred door, Clare has three days of weather, no signal, and eight suspects — one of whom is still working.
