Not sure if there's anything deeper to it but I came across this by pure chance today

https://en.wikipedia.org/wiki/Q_(novel)

"The book follows the journey of an Anabaptist radical across Europe in the first half of the 16th century as he joins in various movements and uprisings that come as a result of the Protestant reformation. The book spans 30 years as he is pursued by 'Q' (short for "Qoèlet"), a spy for the Roman Catholic Church cardinal Giovanni Pietro Carafa."
