Poe would start the story just here, and here the veritable Poe-esque quality begins.
After debate within himself as to means, the nephew murders his uncle and buries him in the thick wall of the chimney.

The Italian laborer witnesses the death-struggle through the window.

While our consciences are aching and the world crashes round us, he levies black-mail.

Then for due compensation the Italian becomes an armed sentinel.

The boy fears detection.
Yet the foolish youth thinks he will be happy.
