Again, I don't know the details; he'll tell you them himself.

I only know that the interesting young person was placed somewhere in a remote nunnery, in very comfortable surroundings, but under friendly superintendence--you understand?
But what do you think Mr.Lebyadkin made up his mind to do?
He exerted himself to the utmost, to begin with, to find where his source of income, that is his sister, was hidden.

Only lately he attained his object, took her from the nunnery, asserting some claim to her, and brought her straight here.

Here he doesn't feed her properly, beats her, and bullies her.

As soon as by some means he gets a considerable sum from Nikolay Vsyevolodovitch, he does nothing but get drunk, and instead of gratitude ends by impudently defying Nikolay Vsyevolodovitch, making senseless demands, threatening him with proceedings if the pension is not paid straight into his hands.
