I didn't hate the old man

[latimeri]

Hallo there.
Does anyone knows who is the author of this verse:

I did not hate the old man, but his grey eye,
That I hated,
In that night there were heigh waters in Fricko.
And so gently, so gently,
I strangled him to death.

[stlukesguild]

Off hand it sounds like a variation on Poe's Tell Tale Heart.
