Book of Blood is a 2009 British horror film directed by John Harrison and starring Jonas Armstrong, Sophie Ward, and Doug Bradley.

The stranger is Wyburd (Clive Russell), who has been stalking the young man, Simon (Jonas Armstrong).

Several months later, paranormal professor Mary Florescu (Sophie Ward) and her partner Reg Fuller (Paul Blair) investigate the house to unlock its mysteriously murderous past.

Mary encounters Simon McNeal, a seemingly clairvoyant young man to whom she develops an attraction.

All three of them hear and witness strange phenomena, including Simon being locked in his room and attacked by ghosts, as well as writing scrawled on walls that bursts into flame.

She admits that as a girl, she had visions of a fountain that spouted blood at night, the burial ground of a serial killer's young victim.

Blood suddenly starts pouring from the case, slowly filling the building that Wyburd is trapped in, and he drowns.

She opens the suitcase, pulls out Simon's intact skin, and smiles as she begins to read the stories still being written upon the flesh.

Adapted and directed by John Harrison from one of Clive Barker's Books of Blood, the film shoot occurred in Scotland, including Dundas Castle and Edinburgh[1] through December 2007 and into early 2008.

During his appearance at Fangoria's Weekend of Horrors, he noted that the film would be followed by Dread, Pig Blood Blues, and then Madonna.
