The best kept secret of Fatima has all the ingredients to be the perfect novel of intrigue, but in turn is a top-level journalistic investigation

The King's secret is a masterful thriller that keeps you on track from the first to the last page, with a surprising ending

I thought I knew almost everything about Fatima, but Zavala convinced me otherwise

El secreto mejor guardado de Fátima es un estudio admirable e impactante, que ayudará a la fe.

Zavala presents us rigorous and exciting investigations that read like a novel

Zavala wrote an excellent biography of Andreu Nin

Died Juan Balansó, Zavala occupies the throne of the regal knowledge

It is fair to recognize the quality of his prose, the rigor of his information, the clarity of exposition

Zavala is a great researcher, Tintin type, able to travel anywhere to find an unknown file

José María Zavala gives us in his books an unforgettable walk of the hand by History.
