Nadie podrá quererle como yo

The young and beautiful princess María Luisa de Orleans, niece of the Sun King, is sent to Spain to marry the most powerful man in Europe... and also the most monstrous, King Carlos II. Against all odds, the unequal couple reaches a good understanding and their marriage is harmonious and happy, except for the absence of the long-awaited heir. The presumed infertility of the queen is the talk of the court and puts her in the crosshairs of the different factions that do not stop conspiring: the nobles, the queen mother Mariana of Austria, the ambassador of France and that of the Empire. One day, the queen herself falls ill and suspects that she has been poisoned. The king, knowing that no one can be trusted, commissions an investigation by Francisco Antonio de Bances y Candamo, the royal playwright, who, much to his regret, accepts the unusual commission when the unfortunate queen dies after a terrible agony, leaving Carlos desolate and the kingdom about to become a spoil for the great powers.
