Alexandre Dumas 
Vicomte De Bragelonne 

The Vicomte de Bragelonne opens an epic adventure which continues with Louise de La Valliere and reaches its climax in The Man in the Iron Mask. As the third instalment of the d’Artagnan Romances, this book serves as a transition from the notorious three musketeers and their Gascon friend to the lives of other French and English characters – youth usurping inevitable age and power subverting nobility. We get a mere glimpse of Porthos and Aramis, a small portion more of Athos in order to indulge his iron-clad honour and still only a bit more of d’Artagnan who reaches the age of retirement and moves his focus from reckless gallivanting and adventure for material comforts which compromise his character.
