For my current project, I am reading trough the book 'Yashka - My life as a peasant, exile and soldier'.
On page 35, she and her boyfriend apparently house a revolutionary who has escaped prison for an overnight stay.

According to her, this man was responsible for the death of a notorious Siberian Governor.
She neither tells the name of that Governor, nor the Revolutionary.

Sadly, I can't speak or read Russian, so it would be very hard for me to find out who she might be referring to, does anyone know these, or where I might find information about them?
