Gibel' Tsarskoi Sem'i (Death of the Imperial Family)
by Nikolai Ross
A collection of 277 documents from the collection of General Mikhail Diterikhs on the investigation of the murder of the imperial family, spanning 30 July 1918 through 21 February 1920.
(Some documents and depositions are duplicated in Ispoved' Tsareubiits,Ubiistvo Tsarskoi Sem'i, and Robert Wilton's Last Days of the Romanovs.)
in my opinion:
this book profile was written by Sarah Miller with assistance from Margarita Nelipa
