La conjura de Cortés, la última entrega de la trilogía de Martín Ojo de Plata, culmina el recorrido de Matilde Asensi por el Siglo de Oro español. Un mapa, un tesoro escondido, un enigmático texto y una conjura para derrocar a la corona española en Nueva España son las claves con las que Catalina Solís tendrá que jugar para poder acabar con sus enemigos, los Curvo.
Now in his mid-50s, Hernan Cortes returned to Spain. Many lawsuits had been brought against him, and he was still fighting for power. He was almost entirely neglected. He finally won the right to join the emperor in his fight against Algiers. The war was not a good one for Spain, and Cortes himself was nearly drowned. He returned to Spain, still neglected and in debt, and finally decided to return to Mexico.
