I won this book from Goodreads and this is my own, frustrated review.
Where to begin? I appreciated this book, but it irritated me as a reader and writer. I likened it to having a strip of Ductape in your hair and each time the following things happened, ripping it off a bit at a time.
When you read a book, you are hearing the story through first person (I), or one or more of the characters, or all of them. This author began in first person, and when ready to switch to another point of view, did not start a new chapter, oh no, just started in someone else's head without warning or explanation. Rrrrrriippppp. This happened so often I lost track of how many times it occurred. It became confusing and disruptive to the point where I couldn't read more than about 10 pages at a time with the frustration.
It even got to the point where when in a character's scene, who is relating third person what he saw.....here comes the narrator into the middle of a paragraph pretending to know what he was thinking.....rrrrrripppp. I can see how the story is enriched in knowing everything that went on, but confusing the reader, and jarring them in and out of the story is not the way to do it. At least start a new chapter when you change point of view. Or do something other than just switch without warning, or context.
Then there were the miracles: the coincidences that could never have occurred joining parts of the plot together. Not a rrrrippppp but more like "am I really seeing this?" reaction. Example: on p142 the second tier character miraculously finds Agatha Christie--- in all of England--- it was too pat, too much of how they could have possibly have found her was left off.
Because when you pick up this book, and read the blurb, you are expecting a mystery, again, it isn't what you would expect. Instead, there is plenty of time spent on the internal dialog of the main protagonist with so many point of view interruptions, you might wonder IF the plot will advance...... until the last line of a chapter.... when the protagonist, in several chapters, hears a scream... rrrrrrippppp, so you keep reading.
I lost track of the unjustified plot leaps. An example: why was the protagonist off on a planned holiday to that particular obscure hotel where most of the last part of the book occurs (we find out in about 100 pages)...how did the love of her life find her in that off the beaten track in a place where they had never been...I'm not sure if this one was ever explained.
The veracity of the main narrator, Nan, tests not just your patience, but your belief. Example: on p169 she inserts remarks and opinions in her point of view in between Archie and Owen's conversation. Then the narration is overlaid by the other 3rd person narration,..... are your eyes spinning? Nan lists what she doesn't know at the time as being kept from her by Chilton--- which makes no point of view sense.
As if she was everywhere reporting this story, she even passes judgement on Chilton's thoughts as if inside his brain. The Ductape is off, at this point.
But there is a payoff: About 60% into the book, I gave up on logic and went with it, no matter where. There actually was a mystery that deepened, as did the drama. The "Timeless Manor" was aptly named and represented the unlikely (trust me) things that followed. The last fifth of the book brought this up to three stars because it at least provided closure, if an odd one.
If, you are oblivious to point of view, and do not mind rereading lines as you become confused, then I recommend this book.
