Why isn't this guy world-renowned? : Has Keilson

Hans Keilson's "The Death of the Adversary" continues to be an original, haunting, important book (now about 80 pages in) - so why isn't this guy world-renowned or at least better known? Because he's not a full-time writer? Because he's Dutch (though I think he first writings were in his native German)? Anyway, Death of the Adversary continues to tell in a most striking way the story of the gradual rise of Nazism and the spread of anti-Semitism from the viewpoint of a youngish (40 or so?) man looking back on his youth. The strangeness of the novel comes from the fact that (so far) he has not uttered any key defining words: Nazi, Hitler, not even Jew. This weird technique makes the book both more mysterious and particular - and more universal. You can't pigeonhole it or dismiss it as yet another Holocaust memoir (as if there can ever be enough) - it's also a story of alienation and terror. Nor can you dismiss it as another story of tender youth, as it's clearly a from-the-life depiction of one of the most horrendous and shameful episodes of world history. The narrator (we are reading papers he supposedly left in care of his attorney) tells of his friends gradually abandoning him, his loneliness, finally his pouring his heart out to one friend who visits from out of town, and this friend tells him that he in fact has become a great following and admirer of "B" (i.e., Hitler). Narrator shamed and angered, but refuses to hate "B," in fact sees something of himself in B's image. Narrator then befriends some others who "bear the mark" (i.e., Jews), and is reproached for being too cool and aloof - unwilling to express his hatred of B. The sense of alienation is palpable - very powerful material.
