Some people think librarians read all day, and I don't know any librarian who does, but working in a library does bring you into contact with excellent books few have heard of. But once discovered, you want to read everything else the author wrote. Marshlands is like that. The mood is like the movie Memento because it starts in the present and moves back in time, but there the similarity ends. The protagonist, Gus, is helped upon his abrupt release from prison by a museum curator. She gives him clean clothes and a useful job, for he had been a doctor. She takes him to a dentist since he had lost his teeth in prison and had difficulty eating. The dentist, disgusted, recognizes this despised man. The former prisoner apologizes to the woman for hiding who he was from her. "I know exactly who you are," she said. "It's a shame you don't know me."
Each of the three chapters moves back in time, movie-like. The book is short, only 164 pages, and not a word is wasted. Olshan is able to portray the mysterious world of the unnamed marsh dwellers with its rich culture, hated by their unnamed foreign occupiers, ending each of the three sections with a punch. It might be possible to identify who Olshan is depicting, but why bother? Despots and occupiers always hate self-enclosed communities that have their own language (the better to plot behind their backs), they hate nomads who move around (where are they now, are they gathering weapons), they hate tribes that sequester themselves in forbidding places to avoid those who torment them (terrorists, guerrillas strike at us for no reason). The despot or occupier keeps the mainstream populace behind them by encouraging hatred and disgust of the separate community (they are diseased, they are inbred, they are backward, they have strange rituals, they worship the devil, they eat babies). They create a narrative for these communities that makes them not-human. And the young doctor's denial of that narrative is his downfall.
