LATE THIS SPRING. Doubleday will be publishing the first dissident novel to come out of Red China. The Coldest Winter in Peking , under the pseudonym Hsia Chin-Yeh. It was a hot book at the Frankfurt Book Fair last fall, with rights sold to England. Germany. France and Spain, as well as the U.S. (It had already made a sensational appearance in Japanese). The author had fled to Japan, where he wrote the novel, and appeared in disguise on Japanese television to promote it. He has now gone totally underground and is living either in Hong Kong or Japan, under a new identity. The book details a failed coup d'etat which purportedly took place after the death of Mao (the novel is reported to be based on fact) and is remarkable not only for showing the privileges of the leadership in the allegedly classless society, but also because it takes the reader under the city of Peking, to reveal the very extensive atomic-proof shelter system built there by and for the elite. The author's thesis is the betrayal of the Chinese revolution and at the least, it ought to put a crack in the Bamboo Curtain.
