Fascinating, wish I could read the book

But since it doesn't seem to have been translated into English, the best I could find are the episode synopses here, translated by Google. http://www.misteriosdelisboa.com/en/series_episodes.html

Fascinating too was what I learned of the author, discovering his life was also marred by tragedy, and was the subject of a film by Manoel de Oliveira, 'O Dia do Desespero' (1992) http://www.imdb.com/title/tt0104099/ -- would love to see this too.
