'For sheer readability he has no peer' Evening Standard Paris in the 1960's caters for every taste, and nowhere more than at the private 'clinic' run by the enigmatic Monsieur Datt on Avenue Foch, which supplies psychedelic drugs and sexual favours to the city's elite - all the while secretly filming guests in order to blackmail them. Into this decadent underworld steps a bespectacled British spy. Sent on what seems like a simple mission, he soon finds himself playing a game where the rules are unknown - and even victory could be fatal. 'Take this excellent thriller at a single gulp' Sunday Times A PATRICK ARMSTRONG NOVEL.
