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 lad who is in fact a lass – supremely talented in dressage, but with no skills suitable to women? Harry resolves to discover the steward’s murderer. The decision is more dangerous than she anticipates.
