Me crazy? Not at all. Let me prove my sanity by describing how carefully and ingeniously I murdered my victim!

I chose a story "The Tell-Tale Heart"  because of two reasons. First, as I saw the author's name, I realised that it's going to be a spectacular story which won't be boring, as I've already read some of Edgar Poe's stories. Second, the  description of the story is very effective, so I'd like to know more about this CAREFULL MURDER)
