I Am Pilgrim is the debut novel by former journalist and screenwriter Terry Hayes.

"Pilgrim" is an American former intelligence agent known as the "Rider of the Blue" who later writes a book on forensic pathology.

Pilgrim becomes involved in a case in New York City where a mysterious woman uses his book to commit untraceable murders in the aftermath of 9/11.

Pilgrim is recalled to the intelligence community who have detected a threat involving the Saracen, who has created a vaccine-resistant strain of the variola major virus.

In July 2014, MGM bought the movie rights for the book and are set to target a series of films, similar to the Bond franchise, with Matthew Vaughn directing.
