I also agree that Michael Occleshaw's book is very interesting. I met him after reading 'The Romanov Conspiracies' and he showed me the grave of Larissa Feodorovna in Lydd, Kent and the house where she and her husband used to live.
We were accompanied by students from a local college, who were making a documentary about 'Larissa's story' and they interviewed Michael and some of the people who live in Lydd and were familar with the story. It would be facinating to see that documentary.
Neither Larissa nor her husband, Owen Tudor, ever claimed that Larissa was Tatiana. In fact he went to great lengths to destroy any evidence of her identity before he died.
The official version of events is that they met when Larissa was in Turkey working as a dancer. They fell in love and married against the orders of the Colonel of Owen Tudor's Regiment, and he had to leave that Regiment in disgrace.
After their marriage they hid away in Lydd, a desolate part of Kent, where the Army Regiment that Owen Tudor joined was based. They lived in a very modest house overlooking a green. When I saw it I commented to Michael that it is the last place you would expect a Russian Grand Duchess to live. Perhaps that was the intention. I read in one of the many Romanov books that someone had once said that even if all the family had not died, it was necessary to say they all died in order to protect any survivors from Bolshevik assassins who might search them out.
Michael has continued his research and I hope he will write another book as he mentioned many additional points to me which are not covered by this book.
He is a serious historian, and he stumbled across a reference to one of the Tsar's daughters being rescued whilst researching 'Armour against Fate - British Military Intelligence in the First World War'. He was then contacted by two ladies who read his book and they told him about the 'Larissa' grave and their research into her background and that of Owen Tudor.
I don't think you can criticise him for not reaching any conclusions in his book. One of the facinations is that there are so many questions about the fate of the Romanovs which have not been answered, and which are unlikely to be answered unless official records are made available, or personal diaries are found which reference the Romanovs.
My personal preference is for authors to set out the facts that have been uncovered, and their source, and let the readers make up their own minds.
