A murder is set to happen in Miss Blacklock's Victorian house, announced in the local paper. The victim is an unfamiliar visitor, not a resident. This triggers a Christie-style enigma of hidden intentions, disguised personas, a second death, and a relentless inspector pursuing the convoluted case. Miss Marple steps in, putting herself in danger, for a climactic resolution. The narrative involves Agatha Christie's signature elements: hidden identities, intricate motives, and a high-stakes unraveling of the murderer's true self.
