London: Michael Joseph, (1962). Hardcover first edition - The 35th book in this series featuring Beatrice Adela Lestrange Bradley, a polymathic psychoanalyst and author. Mitchell was - along with other female members of the Detection Club - Agatha Christie and Dorothy L. Sayers - one of the most prominent authors of that era, as well as one of the most long-lived and prolific. She was unique in having a professional woman as her detective. "Mitchell was a schoolteacher who believed in the idea of the professional, progressive woman. Her title character was controversial and emancipated, and even considered murder justifiable if the occasion demanded. , , Her murder cases have ambiguous solutions, and an air of the supernatural is never entirely banished from them. Her plots are on the farthest side of credulity, but to worry about realism is to miss the fun of her storytelling." (Christopher Fowler) This novel begins on a nostalgic note as her assistant Laura, who has accompanied Dame Beatrice to a conference in Edinburgh, remembers scenes from her childhood in Scotland. 254 pp.
