I have to agree with some of the other reviews. It is not even vaguely scary. The ghost is totally unrelated to the house; he might have appeared anywhere else. Somehow the author did not really do a good job with the story; it was difficult to believe and quite flat.
I think this book is one of the best melancholy novels in existence. Its tone of ironical sympathy with the main character Soames Forsyte makes the reader feel sorry for him, too, despite his inability to understand what his wife wanted and needed; after all, he was depicted as what he was -- a product of his age.
This review in English may be a little out of place here (there is no English edition of any of Stendhal's works on Manybooks) but it is meant to encourage other readers to try this wonderful novel by a writer who is, in many ways, as good as Balzac, without any of the flowery prose.
It would be a real blessing for English readers fond of the historical novel genre to find translations of Stendhal's best works here on Manybooks, but while they are not available, Internet Archive does have some of them.
The novel is itself well executed and the characters well drawn; the conclusion was just a little disappointing however; the author seems to have hurried through it. Nevertheless one of the best. Five stars.
Good, but certainly not in the same league as "Seventeen" or "Penrod and Sam." This book is a bit heavy at times and the narrative seems to drag a little.
