The Lucifer Code (Thomas Lourdes)

Dr. Thomas Lourds, internationally-renowned linguist and archaeologist, has just arrived in Istanbul to lecture at the University. But before he even leaves the airport, Lourds is kidnapped and finds himself fighting for his life--and for all mankind.

Deeply hidden somewhere in the city is an ancient scroll written by the author of the Bible's Book of Revelation--a scroll whose secrets might save or destroy humanity. Lourds' religious extremist captors need him to help find the document to achieve their evil ends. After a desperate escape and chase, Lourds searches for the scroll with the help of a former lover, Olympia Adnan, and a deadly Irish mercenary he cannot trust.

Lourds and his dangerous allies must navigate ancient Constantinople's darkest depths to find the scroll before the Devil himself brings the world down around them and the war between good and evil comes to a final showdown.
