John Gardner, who carried on the grand spy tradition of Ian Fleming's incomparable James Bond, now presents an explosive novel of intrigue and suspense that sweeps through three turbulent decades--marking the beginnings of the British secret service. From the advent of World War I to the rise of Nazi Germany, the Railtons-a proud and aristocratic family of soldiers, diplomats, and civil servants-turn their talents and patriotism to the practice of intelligence. And a newfound family tradition of espionage leads to a desperate and decisive undercover game of loyalty... and betrayal.
