Here's our pick as the dark horse of the moment. There's no moss on Dr. de Savitch and this is nonpareil personal history of a man who has lived many lives, told with appreciable humor and spirit. At 14 he left Russia, when the revolution proved the first of many reversals. He went to Japan, worked in a bank, a hotel, a ballet, posed as the aristocratic ""front"" for peddling Tatar thieves. He joined, briefly, the White Army in Siberia, and then came to America. T.B. put him in a sanitarium for two years, where he was fired with the desire to become a doctor. He worked his way through Universities of Denver and Colorado by doing laboratory research. And the balance of his career is in medicine, -- Pasteur Institute, Belgium, working on T. B., rounding up specimens of sleeping sickness in the Congo, etc. His cataclysmic experiences, his flair for landing right side up, his neat turn of phrase and his first rate medical data -- all makes grand reading. A better book than Arches of the Years or San Michele, I think. Don't miss it.
