The most interesting things he discovers are that as a consequence of describing the owner of the flat downstairs as a money hoarder the authorities thought there might be some truth in it and made his life difficult. That he did have a brother Nikolai and he died in exile in Paris. But the interesting thing that this topographer cannot explain is the most important two streets in the book – where the Turbins live and where the woman who saves Alexei lives - have their names changed while everything else stays the same.
The final thing that you have to remember is that the book followed a play The Days of the Turbins, which Stalin liked so much he saw 15 times and when Bulgakov found the censorship and life in Russia so hard he pleaded to be allowed to go into exile it was Stalin who telephoned him and made him stay - not someone you could really argue with.
