The Tell-Tale Heart
Published in 1843, "The Tell-Tale Heart" is Edgar Allan Poe's masterwork of psychological terror, exploring the unreliable perspective of a narrator who insists on his sanity while describing increasingly deranged behavior. The story exemplifies Poe's genius for creating mounting tension through internal monologue and sensory obsession, examining how guilt and paranoia can destroy the mind from within. Readers should expect a claustrophobic descent into madness told entirely from the perpetrator's viewpoint, with the famous heartbeat as both literal and metaphorical symbol of inescapable conscience.
