Query: The best book of the author

My favorite Josephine Tey, dreamy and gentle like a story told by a favorite elderly aunt. Alan Grant, a Scotland Yard detective, is forced to face his own fragility of body and mind, and the plot is largely driven by his imagination and his subconscious desire to resolve a mystery he is not even sure it really exists. There is always an element of beauty in Tey's novels, and here it is stronger than ever - the beauty of Scottish mountains and of people Grant encounters, and of a distant land he imagines. Plausibility (or lack of) of the plot is not important. This book, that often travels with me, always reminds me why we read: to be taken elsewhere, outside of ourselves, to places we would have never seen otherwise.
