Barbara Michaels is a new-to-me author, and one whose other works I will definitely be looking into.
This was a wonderfully creepy book, and scary without being gory (though, I'm not one who minds gore). What we have here is a good old-fashioned ghost story, and Ms. Michaels pulls it off beautifully.
The novel was originally published in 1968, and in a lot ways is incredibly dated (attitudes towards the female characters and so on), but yet still stands the test of time.
I loved, loved, loved the fact that the main protagonist (the book actually features four) was a 40-something year old woman, Ruth. Who has a love interest in the form of a 50-year old man, Pat. So often, the other two protagonists, Sara (Ruth's niece), and her boyfriend, Bruce--both around 20-years old--would have been the main characters, as opposed to the older couple. As someone who in Ruth's age range herself, I found the switch completely refreshing.
I liked all four of the main characters, though, I struggled with Pat especially, at first until...(show spoiler)
This is the first of a trilogy, and I will definitely be reading the other two.
