Thanks, Mr. Dwyer for your comments on Durrenmatt. Durrenmatt is relatively unknown in English-speaking countries and if book publishers ever decide to bring out his untranslated works, it will be thanks to readers like yourself. Are you aware of "The Pledge"? Like "Traps" it's a major work and easily available thanks to the Penn movie of a few years back.
Mark Samuels did me a real kindness and sent me a copy from London of Durrenmatt's one act play, "Conversation at Night with a Despised Character". It was televised on the BBC in 1969 with Sir John Gielgud and Sir Alec Guinness. It's the story of a writer's encounter with the assassin sent to kill him by the State. (Earlier, D. had taken aim at the Black fascists with "Suspicion"; this time he had the Red fascists in his sights.) It's a brilliant work with the author at the peak of his powers.
WARNING: SPOILER AHEAD
The ending isn't a twist; it's a warm pretzel, nicely salted, and with spicy mustard. Any other writer would have the Author lecture and teach the Hangman a thing or two about basic humanity, perhaps even instill deep doubts about the 'rightness' of his profession. But this is Durrenmatt. Guess who teaches who how to "die humbly" and unconquered?
I would have loved to have seen this with those two great actors.
Sorry for the late reply. I haven't read the others works you mentioned, and will seek it. I heard that the The Pledge is sort of a critique of the detective genre. I have some problems about that genre too.
I first heard of Durrenmatt through......Colin Wilson! Another writer that Colin Wilson thought highly of is David Lindsay. And I just recently found out that Colin Wilson was a big fan of Grabinski

Durrenmat, David Lindsay, Grabinski. Colin Wilson had some excellent literary judgment.
