I've just been reading this book while on a trip to Berlin! It proved a great read from a writer I knew a little about but wish I'd read a lot earlier. The main character Orris is well developed and his relationship to the 'centre' - the British secret intelligence - is crucial to this story. Brierley's style of writing is great for building up tension and giving the reader a sense of how MI:6 and other units operated in the chaos of post-war Europe, when anyone was potentially up for being 'bought' by the other side. Particularly well-wrought scenes I read included the one on the rooftop in London on Orris' unscripted return from Europe, when he gets pot shots taken against him by agents who obviously know that he is the last link in a long chain linking back to the destruction of an agent cell in Czechoslovakia. You can feel the bullets flying past your ear! The denouement - which I won't spoil in this review - is believable and well written. I've read a number of these reissues by Ostara publishing over the last year, and Mike Ripley's doing a great job of finding thriller gems and re-polishing them so they don't go out of fashion!
