Sarah Foster should be less disgruntled than she is with her family and life in the Midlands; and she shouldn't be so anxious to furtively meet the roving M.P., Vic Nightingale, who lives well beyond his apparent means; and she certainly shouldn't have left a neighbor's baby alone in her car to be snatched and later found at Mrs. Knox's -- she's a foster mother. Miss Mann has acutely observed the opportunism of quite ordinary people and her very skillful book remains true to life and close to death.
