Flanders, 1625. After his tussles with the Inquisition and the intrigue of the Spanish court, Captain Alatriste has returned to the mud and desperation of the long war in Flanders. This is I igo’s first experience of war and the realities of hand to hand combat. It is on the battlefield that he will finally have the chance to become a man and prove his worth.

The troops are weary and ill-nourished and the winter has been long. As Spain sinks ever further into depravity and corruption, the soldiers have not been paid and must survive by whatever ways they can. Mutiny is in the air, but the Spaniards are strong and their famous iron discipline has brought them many victories against the Calvinist forces of the heretics. Reputation, honour, and the glory of Spain will keep them in the fight, but for how long

Meanwhile, the Captain’s trusted friend Quevedo’s star is rising at court and he keeps Alatriste appraised of the machinations of his arch-enemy Luis de Alqu zar and the notorious assassin with the black heart, Gualterio Malatesta.
