Edgar Allan Poe 
The Pit and the Pendulum – Unabridged [EPUB ebook] 

A prisoner, sentenced to death during the Spanish Inquisition, finds himself trapped in a lightless cell to contemplate his fate.  Will he die by falling helplessly into a deathly, yawning pit in the center of the room?  Or will the deadly, razor-sharp pendulum slowly descending from the ceiling be the cause of his demise?

This is an unabridged copy of the classic story by the Master of Horror, Edgar Allan Poe.
