Carisbrooke, thankyou SO much. "NO RESTING PLACE.........." certainly rings bells and I would certainly have been attracted by the "Romanov" in the title. Alixz, I may well have remembered her name incorrectly, it was such a long time ago that I read the book and certainly have no memory of it being 76 pages short!! Lydd and Hythe are indeed very close, so perhaps it's as well that I didn't search Hythe churchyard during a thunderstorm!!!
A postscript to this is that whilst on a cruise to Russia, two authors, a husband and wife, gave a talk about a book they were writing on one of the Grand Dukes-Michael who married Natasha? I spoke with them afterwards about the book I had read, which not unreasonably, given what has transpired, they dismissed as total rubbish. Might it be possible that those authors were the Crawfords? They were hugely knowledgeable about all things Romanov and thankfully,since then, my own has grown.
