Letters from an unknown woman a novel

"With her children evacuated and her husband at the front, Tory Pace is grudgingly sharing the family home with her irascible mother, working at the local gelatin factory--to help the war effort--and generally doing just about as well as could be expected in difficult times. Her quiet life is thrown into turmoil, however, when her prisoner-of-war husband, Donald, makes an outrageous demand for sexual gratification. He wants a dirty letter"--Dust jacket flap.
