It is estimated that during the peak of the Great Purge in the USSR some 680,000 to 1,200,000 people were killed by NKVD. An average investigator in Moscow had some 30-40 political cases per month. And sometimes they were bored.
I found this book in an old books department in the Russian city of Novorossiysk. This sample of Soviet samizdat was supposedly made in 1970s and is literally a photo copy of a 19th-century book.
