A tale of suspense with gothic, mystery and romance elements. It is obviously popular fiction but is quite good. It took me a little while to get comfortable with du Maurier's sentences which can sometimes be peculiar. The story is interestingly transgressive in that the hero essentially gets away with murdering his first wife and there is nothing seen as problematic in this at all. One can understand the hero's predicament, but is an interesting attitude to take, and, while I haven't checked, I imagine the story is denounced a fair bit over it.
Well worth reading. I enjoyed its gothic elements and the smooth flow of the story. The main character who is very timid is remarkably well done/ One of the best works of popular fiction that does not have a great deal to say that I've read.
