When someone starts assassinating paparazzi in three countries, MI7 sits up. Apparently, the killer is none other than Dmitri Vassyli Kramski, retired SVR field-operative and former Kremlin protégé.
True, the Cold War is long finished, but everyone knows Vladimir Putin is as unhappy for Russia to play second fiddle on the international stage as even the most strident of his Communist predecessors. In 2010 therefore, East-West relations remain as tortuous as ever.
Kramski's trail leads deep into London's émigré community, forcing his pursuers into conflict with an unknown organisation bent on protecting him. Bit by bit, he begins to look less like a professional assassin and more like someone plotting to scupper the foundations of Western democracy itself.
To compound matters, the Russians are as baffled by him as anyone.
