A mild little suspense novel about some scary happenings taking place in the Manhattan brownstone of an affluent family in the 1920's. The narrator is 25-year-old Grace--whose fiancÃ‰ was reported missing in WW I; who has forsaken the life of opulent nothings for teaching and study: and who is now being discreetly courted by lawyer Ned. Siblings have left the family brownstone to marry and, in addition to bluffly demanding Papa and vague Mama, there are only the servants left. But then brother Alfred, wife Ann, and children move in after Alfred's humiliating (and mysterious) bankruptcy. And suddenly younger sister Rose, whose elopment four years ago to handsome Jack broke the family's collective heart, returns--sick and strange. Even before the Return, unexplained footsteps are heard on upper floors, doors slam, and a strange figure is seen opening the front door. Then a housemaid is apparently pushed to her death, a cat is found strangled, and Mama dies trying to communicate--something. Does the family call the police? Certainly not--scandal. Of course, Ned and Grace sleuth it through--more or less--and there's a stabbing murder plus two post-mortem confessions. So-so suspense walked through by flat characters, but the one-family brownstone background is always appealing.
