This was disappointing, but that truly is partly due to my expectations. I had read about this book in "Murder, She Wrote" in which the book was described as a page-turner, with the main character starting to see things. This logically makes her doubt her sanity.
I thought this was going to be like Shirley Jackson's writing, specifically The Haunting of Hill House, which is one of my favourite novels of all time. However, this was far more like Mary Stewart's Thornyhall. That's not a bad thing at all; I read that book a while ago, and thought it a cutesy, charming sort of novel, albeit one with little substance to it. The problem here is that I expected a dark, gothic sort of read, maybe even horrific; instead, I got a lot of mundane stuff.
The story is all about forty-three yo Virgilia, who starts to see things which are not really there. Quite early on, these visions are explained as her being able to see the future. This, of course, brings a lot of questions with it; will what she sees invariably happen, or can she change the future? This is an interesting concept, and probably fresh, maybe even revolutionary in 1946. Anno 2019, however, it has been done before, with much higher stakes than in The Unforeseen. The novel takes forever to get to an interesting vision (almost halfway; the other visions are all mundane things, like predicting what sort of dress Virgilia's daughter has ordered). The ending, too, was utterly predictable, and the relationship between Nan and Perry felt flat to me.
Not all was bad. I loved the Irish setting, and I think the relationship between Virgilia and her mother was beautifully done. The writing was lovely, too. Sadly, the stakes were simply too low for me to keep caring.
I am sorry I did not enjoy this novel more. However, I have heard good things about Dorothy Macardle's other book, The Uninvited, and I still really look forward to reading that.
