Alnwick Castle vampire

Some 800 years before the publication of Dracula, and long before the term "vampire" was popularized, an English historian, William of Newburgh, recorded a tale recounted to him by a devout and reputable priest. He told of a most dishonest sinner who escaped the law by retreating to Alnwick Castle. 

There he married, but was soon confronted with rumors his wife was unfaithful. He climbed atop the castle's roof to spy on her, and discovered the rumors were true. Shocked, the man fell from the roof and died. However, it was soon apparent the man was not dead at all, but rather a wandering undead revenant, spreading plague wherever he traveled. 

It was decided to dig up the man to inspect his corpse, and upon doing so, it was discovered to be bloated with fresh, warm blood. The body was immediately burned on a pyre, cleansing the air and releasing the land from the clutches of the man's plague.
