Antonio Perez, "Spanish Traitor"

Marañón, Gregorio, Antonio Perez, "Spanish Traitor", (Translated from the Spanish by Charles David Ley), London: Hollis and Carter, 1954.

Antonio Pérez (1540–1611) was a Spanish statesman, secretary of king Philip II of Spain. He was said to have organised the murder of Juan de Escobedo. Attempts to prosecute Perez led to riots and disorder. He eventually fled Spain after being liberated from prison by his supporters, and spent most of his remaining years in France.

Gregorio Marañón y Posadillo (19 May 1887 in Madrid – 27 March 1960 in Madrid) was a Spanish physician, scientist, historian, writer and philosopher. (...) An austere, humanist and liberal man, he is considered one of the most brilliant Spanish intellectuals of the 20th century. He also stands out for his elegant literary style. He was a Republican, fought the Miguel Primo de Rivera dictatorship though he later showed his disagreement with Spanish Communism.
