by Nicolas Nabokov. Atheneum, $12.50. From his childhood in the fairy-tale luxury of the tsarist aristocracy, through exile, success as a composer, war service, and uncountable comings and goings, Mr. Nabokov has enjoyed an exceptional gift for finding friends who were also people of distinction and accomplishment. His memoir, which tells nothing of his domestic affairs, is a tribute to those “delicious and dedicated friends,” and his intention (quoting Ariel) is “to please.” It will be a glum reader who is not pleased to meet the likes of Stravinsky, Diaghilev, Harry Kessler, cousin Vladimir, and W. H. Auden, or to spend a safely vicarious drunken evening with Isadora Duncan and Esenin.
