Pardonable Lies (Maisie Dobbs #3)

A deathbed plea from his wife leads Sir Cecil Lawton to seek the aid of Maisie Dobbs, psychologist and investigator. As Maisie soon learns, Agnes Lawton never accepted that her aviator son was killed in the Great War, a torment that led her not only to the edge of madness but to the doors of those who practice the dark arts and commune with the spirit world. In accepting the assignment, Maisie finds her spiritual strength tested, as well as her regard for her mentor. The mission also brings her together once again with her college friend Priscilla Evernden, who served in France and who lost three brothers to the war -- one of whom, it turns out, had an intriguing connection to the missing Ralph Lawton.
