My review of The Secret Rooms from 2013:
The Secret Rooms, billed as A True Gothic Mystery, is a kind of biography of the 9th Duke of Rutland. I found it an interesting enough read, but I felt it didn't quite live up to the title and the really intriguing cover.
The book opens with the death of the Duke in 1940, then the author describes how she came across his story some years later - she had set out to research something slightly different. While looking at his papers, she discovered that someone, probably the Duke, had been keen to conceal various papers and that it appeared he had something to hide - what was it?
I enjoyed the look at the life of an aristocratic family in the early 20th century, before and after WWI, but felt a bit like saying, is that all there is to it? at the revelations. I think part of the problem was that the author kept writing about the sensational secrets she was uncovering, and they weren't that sensational.
The print book comes with some black and white photos (not that well reproduced) of the Duke and his family, and various maps and plans of his estate, his home, Belvoir Castle, and other significant places in the story, and lots of endnotes detailing the author's references.
This is clearly meticulously researched and an interesting read but the mystery is not as exciting as the title leads one to expect.
