Does anyone know much about Satyen Barkataki?

My apologies, I don’t speak Assamese. I am researching on Satyen Barkataki, the brother of Munin Barkataki and brother in law of Renuka Devi Barkataki. He wrote and published extensively and it’s hard to keep track. I have his English written autobiography of his career as a magistrate known as “Escapades of a magistrate”. There is a biography on him in an Assamese book published from the Munin Barkataki trust but I’m not proficient and it is difficult to find for me. He’s a very interesting civil servant with experience in Mizoram and Nagaland as deputy commissioner. I’m hoping if anybody can help find information or help with his accessing his biography book “সত্যেন বৰকটকী: জীৱন আৰু কৃতিত্ব”. My apologies for any ignorance on the matter or related.
