Q by Luther Blissett

Q is a historical thriller set during the chaos of the Reformation in the 16th century. The narrative unfolds as a radical Anabaptist, who travels under many names, is pursued across Europe by a relentless papal spy known only as "Q". The novel explores the religious wars and political struggles of the era, culminating in a mission that can only end in a final, fatal meeting. The book was originally published in Italy in 1999 and written collaboratively by a group of Italian left-wing activists under the pseudonym Luther Blissett.
