Unknown Person

Adventurer James Keziah Delaney returns to London from Africa in 1814 along with fourteen stolen diamonds to seek vengeance after the death of his father.

Twenty-eight days after a killer virus was accidentally unleashed from a British research facility, a small group of London survivors are caught in a desperate struggle to protect themselves from the infected. Carried by animals and humans, the virus turns those it infects into homicidal maniacs -- and it's absolutely impossible to contain.
