Paris in 1968—seething with revolutionaries and spies—sees Will Flemyng's world turned upside down, after a mysterious encounter on the metro and a chance revelation from a rival operative. In a city alive with talk of revolution, Will finds himself in the thick of the action, a young spy whose first adventures behind the Iron Curtain have already given him a secret glamor. But now he gets news that threatens the closest and most complicated relationship in his life, with his younger brother.

In the unforgettable weeks of a crisis that claims blood and tests his deepest loyalties, Flemyng lives and loves the tumult of a city in which his private fears teach him the secrets that lie beneath the raucous politics of the streets. This is the making of the man whose journey leads to The Madness of July—Will Flemyng, trapped with his friends and enemies in the Paris Spring.
