Back in the USSR =: Eshche Raz' [I.E. V] Sssr

By evidence of this silly travel diary, the Daviesesthe author, his wife and their teenaged daughterwho ventured from their London digs to Moscow and the Black Sea, are quintessential innocents abroad. This is the shallowest book about the U.S.S.R. in memory, and more's the pity that the family flubbed the opportunities provided, especially since the trip was paid for by the Soviet government. In Moscow they dined at the homes of writers and visited editors at their offices; on the Black Sea, at a writers' resort, they met not only the vacationing Soviet literary establishment but also poets from Nicaragua, Turkey, Hungary. The Davieses, to be sure, had a swell time, and no matter that they found the Cyrillic alphabet ``utterly potty'' and Moscow ``countryfied, the pace slow,'' yet the little of substance related here could have fit on a postcard.
