All Men Glad and Wise by Laura C. Stevenson

In 1919, Harry Green, stable lad, discovers the body of Willingford Hall’s steward. The investigation proves that Willingford Hall is nearly bankrupt. What will happen to Harry’s father, the estate’s head groom, as automobiles are making grooms unnecessary? And what will happen to Harry, a consummate rider, but a lad who is in fact a lass with no skills suitable to women? Harry resolves to discover the steward’s murderer. The decision is more dangerous than she anticipates. A murder mystery, a coming-of-age story, and a portrait of changing English society, centered upon splendid horses and dressage. “A well-researched and convincing period whodunit.” Kirkus Review
