The Tell-Tale Heart

Do not call me mad! What I did was not done out of malice or accident. Nay, every element of it was planned, every detail thought through. My methods were exact and executed to perfection. This horrible crime will never be discovered, as I left no clues to visit justice upon the act. Even the police, who now roam this house, are completely unaware of what lies beneath their feet. If only they don’t hear that beat, beat, beat... that ever-louder heartbeat.
