Sorry, I meant the Edgar Allan Poe story, "The Tell-Tale Heart." I forget that not everyone is an English teacher like me :) Gunslinger read it in school yesterday, LOVED it, and is off reading more Poe stories :)
But since she also likes ASJ, I thought I remembered someone writing one with a similar theme of guilt and obvious TTH allusions. I haven't had much luck though with the search function here.
