What is the author's style in The Daughter of Time by Josephine Tey?

Josephine Tey's writing is obviously that of an English woman. There is a rich quality to her dialogue and narration and an authentic quality to her speech and language. She occasionally reverts to specific dialects, such as The Giant's Gloucester accent, and uses French through Grant as he inspects French documents. Her writing is dense but meaningful, without unnecessary words. In fact, it is a tribute to her that the book is so small, since she tells a story with an impressive amount of detail. One does not need to be a scholar of British history to gain a considerable amount of insight into the nature of medieval England's politics and shifting power.
