"The Key to Yesterday" by Charles Neville Buck is a novel written in the early 20th century. The story is set against the backdrop of horse racing at Churchill Downs and introduces readers to complex characters navigating the realms of love, identity, and artistic ambition. The main character, Robert A. Saxon, is a painter who grapples with his mysterious past and the emergence of profound feelings for a woman named Duska Filson as he embarks on a new journey in his art and life. The opening of the novel immerses readers in the excitement of the Derby Day races, where Saxon becomes captivated not only by the thrilling competition between horses but also by the striking presence of Duska, a young woman amidst the crowd. Their initial encounter is characterized by awkwardness, admiration, and the beginnings of a more profound connection. As the story unfolds, the contrast between the thrill of the races and Saxon's introspective artistic pursuits sets the stage for a deeper exploration of themes such as identity, connection, and the complexities of love, particularly as Saxon harbors a haunting secret about his past.
