A terrific novel about political repression in South America ca 1980

The short novel by Uruguayan author Mario Benedetti, Springtime in a Broken Mirror (1982, in English 2018), is - through the first half - a fantastic and disturbing account of the political climate in South America during the late 20th century; the novel is the story of a young father imprisoned for his political activism in Uruguay - but, in its brief and subtle manner - it's really the story about how the incarceration of this one man, Santiago, has ramifications across a broad expanse of characters. Benedetti builds the novel in a series of brief sections from 5 (I think) points of view: Santiago in prison (told from his letters to his wife), his wife (Gracia?), his daughter age about 8 (Beatriz), his father (Rafael, I think), and his best friend (Rudolpho). What we see over the course of the narrative is Santiago's yearning for his wife and his struggle to get through imprisonment without providing any information to his captors/torturers, while his wife feels increasingly estranged from him and falls in love w/ his best friend. She confides in the father-in-law, who offers sage though unexpected advice (he has some of the most powerful brief chapters including one at the heart of the novel that gives a harrowing and poignant account of the effects across a culture of political oppression). The daughter's brief and sometimes funny sections give us a child's point of view on the trauma of political imprisonment as she reflects on her family and her community (the family fled Uruguay and are now living as political exiles in Buenos Aires). The use of alternating short sections makes this novel, on such painful subject, easy to read and to comprehend - though, as a side note, I'm not sure why MB wouldn't intro each section w/ the name of the speaker nor why he would give 2 of the 5 main characters a name beginning w/ the same letter (something a screenwriter or dramatist would never do).
