This was a brilliant read! The Secret Rooms - A True Gothic Mystery by Catherine Bailey is the result of a tonne of research delivered in a gripping narrative non fiction style that had me telling multiple people about it before I'd even finished.
If you'd asked me if I cared about the life of the 9th Duke of Rutland and his family, I'd have said no. What about the history of Belvoir Castle? I'd probably have given it a Google, marvelled at the impressive architecture, looked at any available images of the interiors and then moved on. So why did I pick this book up? In one word? The blurb! (Or is that two words?) The blurb contained a really good mystery I wanted to know more about and I love when rooms are locked for decades and then re-entered.
In 1940, John the 9th Duke of Rutland was one of Britain's wealthiest men, yet he died holed up in the servant's quarters of Belvoir Castle. Living out his last days secluded in an area comprising five damp rooms, doctors firmly encouraged him to move to luxurious accommodations elsewhere in the castle but John refused.
After his death, John's son closed up the rooms and they remained locked and untouched for sixty years. Author and researcher Catherine Bailey was one of the first to be granted access to these rooms and there she discovered what John had been feverishly working on right up until his death. Of course I wanted to know, don't you?
The Secret Rooms was published in 2012 and it's mentioned in the blurb so it's not a spoiler to say that John was an obsessive collector and had been organising and cataloguing his family's correspondence. The family archive contained hundreds of files spanning nine hundred years of history and contained tens of thousands of documents. On closer inspection, the author discovered that letters for three distinct periods in John's life - in 1894, 1909 and 1915 - had been removed from the collection. Why? Was he trying to hide something? And what was it?
Bailey draws on the contents of the available letters and diary entries in addition to military records and other sources in order to piece together what happened in John's life during these periods that he was trying to conceal.
Belvoir castle is in Leicestershire and built in the Gothic style with 356 rooms and I loved learning about it. It's an impressive looking structure and thankfully the book includes a comprehensive floor plan which was incredibly useful.
"The servants - maids of all descriptions, odd-job men, footmen, the flag man, the hall porter, the telephone boy, the boiler stoker and the stewards' room boy - were seated on the two benches that ran either side of a long table beneath a photograph of King George VI." Page 14Of course, this wasn't all of the servants, you also have the housekeeper, butler, valet, chaplain, coal carriers, watermen, watchmen, lamp men and more. It's like Downton Abbey on steroids.
"In 1899, the castle had a groom of chambers, a house steward, an usher of the hall, a chef, a pastry chef, a confectioner, a plate butler, a clockman, a steward's room boy - and housemaids, kitchen maids, scullery maids, footmen, odd-job men, and porters galore." Page 169
"In the castle's grounds, there were hundreds more: grooms, stable lads, dairy maids, studmen, brewers, rat catchers, mole catchers, millers, mechanics, gardeners, groundsmen, gamekeepers, river keepers, huntsmen, kennelmen, slaughtermen, stockmen, horsemen, farm hands and woodsmen." Page 169Bailey explains that in 1914, there were thirty Dukes - the highest honour the Crown could bestow - and they enjoyed privileges that seem scarcely credible to today's reader. This family had ruled over the neighbourhood for eight hundred years and some of the scenes described of family funerals held on the estate were extraordinary.
The astute among you will have noticed that one of the gaps in John's family correspondence occurred during the First World War and it's fair to say that a good deal of the research Bailey relates takes place during the war. This may deter some readers, however the author strings the narrative together so well by including telegrams (damnation!) and letters that keep the pace trucking along and on topic.
Bailey takes the reader along for the ride and has distilled John's life to a ripping tale and I thoroughly enjoyed getting to the bottom of the three 'secrets'.
In the Acknowledgements section of the book, the author thanks her mother Carol for deciphering and typing out the many thousands of letters she found. I have so many questions about this and the book that I'm currently trying to track down the author in order to invite her to conduct an interview with me for Carpe Librum. Catherine, if you're reading this, I'd love to know more about your research for this book so please get in touch.
The Secret Rooms by Catherine Bailey contains family secrets and cover ups, overzealous matchmaking, military movements and misdeeds, cryptology, pathological behaviour, aristocratic abuse of power and a privileged way of life many of us cannot begin to comprehend.
Highly recommended and an unexpected contender for My Top 5 Books of 2026.
