The sundial
The Sundial is a haunting gothic mystery set within the decaying Halloran mansion, where the death of its master, Lionel, sets off a chain of unsettling events. His widow Maryjane is convinced his mother Orianna murdered him, and as the household's inhabitants—a governess, a sickly uncle, a young man in the library, and a sister—each grapple with their own secrets, the house itself seems to conspire against them. When a prophecy of the end of the world surfaces, the truth behind the family's past and the meaning of the sundial's cryptic inscription becomes dangerously clear.
