1568 was one of the most terrible years in the rule of King Philip II of Spain. Conflict grew in Flanders, the Turkish threatened the Mediterranean, and Moors rebel in Granada. However, the King is set to face all the problems. With the help of his skilled secretaries he puts in place his best secret weapon: a network of spies never known before. Double agents aplenty his majesty has to turn to someone he can trust: knight clerics who have sworn loyalty to the kingdom. Two young knights, Luis María Monroy and Juan Barelli, start a journey towards the East with the hardest and most engaging secret missions the king can ever order. The trip to Istanbul will be a dangerous journey, filled with adventure and risk and a surprising ending. Once again, Jesús Sánchez Adalid writes a page turning tale of love, honour and courage, and enthrals the reader with the best written story in the Monroy saga.
