1887, the Cornwall coast. For years, rumors have flown through the village of Suttonsbury about Ashthorne Hall, but botanist Hyacinth Bell only cares about the estate's one-of-a-kind orchid collection. As an independent woman, she is eager to focus on her career. What she doesn't expect is to be swept away by Lucas Harding, the manor's caretaker. But then strange things start happening in the seemingly empty halls of the estate. Armed with little more than her instincts and her courage, Hyacinth must venture into the shadows of Ashthorne Hall to uncover the truth before she falls victim to the dangers hidden in the estate.
