I'll probably be the last blogger to register the death of Richard Matheson, but he was so influential and so good, I can't let it to unnoticed.
I'm just dropping off to do some vacation-time, so here's only a short list of some of his work I've really liked:
Duel: both Spielberg's movie and Matheson's original short story plus his screenplay.
I Am Legend: unbelievably suspenseful, yet tight and relentless, very short (only some 150 pages), but still packs quite a punch, a model for many vampire and zombie novels and films to come.
Someone Is Bleeding: the original novella (later published in book form) reprinted in the great anthology American Pulp, goes to show Matheson was a very good noir crime writer.
short story "Gunsight" (Dime Western, 1951), published in Finnish as "Sokean sheriffin kaupunki" (meaning "The Town of the Blind Marshal"): hypnotic Western story of a blind hero.
