Just finished Archangel by Robert Harris, who wrote the very excellent Fatherland, and Enigma. This one is about a dissolute academic who falls in with an unscrupulous tv reporter to find Stalin's long-lost son. Well-paced and plotted; the characters are well fleshed out, and the book is solidly written. But, for me, this has all been done before, and better. It just fell flat. If you need a good book to pass the time on a flight, then this is it. Looking for that extra something? Then give it a miss.
