Answer: In The-Tell Heart the narrator confesses because of his guilt. I know this because during the story when he's with the police it says and I quote "My head hurt and there was a strange sound in my ears. I talked more, and faster. The sound became clearer. And still they sat and talked." and then "Suddenly I knew that the sound was not in my ears, it was not just inside my head. At that moment I must have become quite white. I talked still faster and louder. And the sound, too, became louder. It was a quick, low, soft sound, like the sound of a clock heard through a wall, a sound I knew well. Louder it became, and louder." which represents his heart that he hear during his talk with the officers because of the guilt he had. it also says " Louder, louder, louder!
Suddenly I could bear it no longer. I pointed at the boards and cried,
“Yes! Yes, I killed him. Pull up the boards and you shall see! I killed
him. But why does his heart not stop beating?! Why does it not stop!?” He thought it was the mans heart when it was his because he was guilty for killing the old man
