Something of a publishing sensation elsewhere in Europe, Q is a convoluted historical thriller by a consortium of young pseudonymous authors, who, it has to be said, are a little too in love with their own cleverness. Q is the working name of a papal spy trying to keep a lid on the Reformation, particularly on the Anabaptist radicalism which is its form most dangerous to the social order, and for decades he watches, and occasionally gets in close and betrays. The man sometimes known as Gert is his opposite--all the more so because he hardly knows of Q's existence--the idealist who is caught up in the same events: Luther's sermons, the rise and fall of Thomas Muntzer, the disastrous People's Republic of Munster. Parallels are being struck all over the place with radicalism in the 20th century--part of what makes Gert a memorable voice is a combination of zeal, pragmatism and survival instinct that keeps him one step ahead of the Inquisitors for 30 years and enables him to, for example, do serious damage to the Holy Roman Emperor's favourite bankers. In the end, Gert and Q are left with more in common than the past they share--the rules are changing and the board is being cleared, and there is time for one last crucial intervention... This is ingeniously plotted, and full of vividly realised scenes of 16th century life; if it has a fault, it is that we live through every day of three tumultuous decades, every sermon and theological treatise, in exhausting detail. --Roz Kaveney
