Will Flemyng was a spy who turned to politics and is rising to the top in the 1970s. But when a bizarre death, on one hot summer day in London, starts to unravel some of the most sensitive secrets of his government, he's drawn back into the shadows of the Cold War and begins to dance with danger once more.

Buffeted by political forces and the powerful women around him, and caught in interlocking mysteries he must disentangle - including a potentially lethal family secret - Flemyng faces his vulnerability and learns, through betrayal and tragedy, more truth about his world than he has ever known.
