This is a family saga, a very popular genre at the time it was published in 1981, but with a difference - the central character around whom the plot revolves is a psychopath. The book is set in the American Deep South and deals with the social and racial attitudes of the period it covers, from 1903 to some time in the 1970s.
Ruth Yancey is the uncannily beautiful daughter of a drunken, abusive, mentally disturbed mill worker who is also a part time preacher of the fire and brimstone kind, and his downtrodden wife, Pearl, who still has enough gumption to pass on her extremely jaded views of how to get on in life and make the most of opportunities to her daughter. Thanks to that, after having to make a horrific sacrifice, Ruth finally escapes her home to move into the beautiful house she has set her heart on: Fox's Earth, the grand house of the wealthy Fox family. She soon acquires the education and graces that a great southern lady requires in the early 20th century, but within her there is a cold hard kernel of hatred for the upper class folks among whom she lives, and she soon sets about engineering their destruction and gaining the house for herself.
As years pass, no one is safe from her mania - fueled by visions of her lost mother, Pearl, who apparently eggs her on - not even her own daughter or grandchildren as her manipulations mould them into the vulnerable personalities she needs them to be. Only Rip, the black servant who joins the household initially to take care of Ruth's daughter and then stays on to perform the same duty for her grandchildren, sees what she is really like and tries to shield her victims. But Rip's own family are not immune from her malign influence.
In places the style is baroque and overblown - Ruth has a 'glow' which encompasses her like a nimbus. One life after another is blighted, and the author usually telegraphs the fact well in advance: we are told that a certain person will die, even the manner of their death, or will have to leave, and then the story goes back and shows how that comes about. This means that there isn't much suspense, and I felt discouraged from sympathising with any of them, because they would soon be bumped off etc, apart from Ruth herself and possibly Rip who is almost like her good other half ... in fact, the story deals with the idea of people who are your 'other end' as Ruth calls it, so that you know what they are thinking without them having to say. Rip has an amazing radar for what Ruth is up to, but it becomes more difficult for her with advancing age to stay ahead - plus, as a servant, and a black person in the Deep South and in that era, she has the odds stacked against her. To some extent, it is credible that she stays on to try to protect the children, given Ruth's threat early on to sack her and make sure she cannot get work if she opposes her, but the revelation near the end of the story that something happened to Rip's own family member 15 years beforehand did stretch that credibility - surely there is only so much someone can put up with in silence? Rip is the most sympathetic character in the novel, though an exemplar of the faithful family retainer, and ultimately a bit of a cliche sadly.
The edition I have has a spooky cover with a crack in the earth beneath the house which has a human form - it reminded me of a mandrake. I think the publisher was trying to cash in on the connection with Siddon's horror novel, as that is prominently referred to on the cover: 'The House Next Door'. However, despite the low-key psychic elements such as Rip's ability to guess what Ruth is up to, and Ruth's visions of her mother, this is not horror fiction.
Given the issues I found with the book, ultimately I could only award it a 3-star rating.
