Tomas Rezac (needs diacritics) (1935-1992) was a Czech journalist and detective fiction writer who knew AS in Switzerland. His book is much reviled by the Russian pro-AS contingent. I don't trust it fully, but there is a lot of negative info in it that is not discountable. There is a better book still, A.Ostrovsky http://www.litru.ru/br/?b=120348&p;=1.
