Good and holding reading, this modern story by the author of the historical trilogy, -- Deep Summer, The Handsome Road, This Side of Glory. Elizabeth, 44, is married to a successful Hollywood director, and with their three children (Dick, the eldest, is 17) they seem to have all that life can offer, shadowed only by the threats of war. Mary's first husband had been called in the last war -- and the knowledge of the imminence of Dick's induction is unbearable. Into their lives comes the German refugee writer, Kessler, strangely familiar. Actually, he is her first husband, when she had believed dead. He had been a prisoner of war, crippled, and reported dead. A German doctor has experimented with him, brought him back to usefulness, and the Jewish forced him to leave Germany with the daughter of his benefactor, who -- with his wife -- had committed suicide. He seeks friendship with Elizabeth, protests her from the truth, but gives Dick the answers as to the whys of war. A problem novel, well handled, avoiding the pitfalls of dubious sentimentality, false emotional values and cheap writing. The publishers are launching it with substantial backing in advertising and promotion.
