Edgar Allan Poe's "The Tell-Tale Heart" is a story about a madman who kills an older gentleman. The relationship between the two men is unknown because the narrator does not describe it explicitly. As far as the relationship is concerned, the narrator only says the following:

I loved the old man. He had never wronged me. He had never given me insult. For his gold I had no desire.

First, the narrator admits that he loves the old man who he wants to kill. Then he seems to suggest that the two have a history together because enough time has passed for problems with the relationship to occur, but there haven't been any. Also, since the two men live in the same house together, it can be inferred that they are related in some way. One might infer that the narrator is the son or grandson of the old man. Again, there is not clear evidence to suggest otherwise, so the reader can only infer as to the status of the relationship between the two men.
