The Masque of the Red Death

The story follows Prince Prospero's attempts to avoid a dangerous plague known as the Red Death by hiding in his large converted abbey home. He and many other wealthy nobles, hold a masquerade ball using seven rooms in the abbey, each decorated with a different color. The last one is velvet black.
In the midst of their revelry, a mysterious figure disguised as a Red Death victim enters and makes his way through each of the rooms...
The story follows many traditions of Gothic fiction and is often analyzed as an allegory about the inevitability of death, though some critics advise against an allegorical reading. Many different interpretations have been presented, as well as attempts to identify the true nature of the titular disease.
