Demelza sees a horseman riding down the valley and senses disruption to the domestic contentment she has fought so hard to achieve. For Ross has little option but to accept the summons - and travel to Paris with his family, as an 'observer' of the French armed forces.

Parisian life begins well with an exhilarating round of balls and parties. But the return of Napoleon brings separation, distrust and danger to the Poldarks . . . and always for Demelza there is the shadow of the secret she does not even share with Ross.

In his Poldark series, Winston Graham explores the complications of love lost and the class struggle of early 19th-century England with a light comic touch. The Twisted Sword is followed by the twelfth book in the Poldark series, Bella Poldark.
