This view interested me very much. But M. could give me no reason for thinking so. And strange to say, I knew Petrov for several years afterwards and talked to him almost every day, he was genuinely attached to me all that time (though I am absolutely unable to say why) and all those years he behaved well in prison and did nothing horrible, yet every time I looked at him and talked to him I felt sure that M. was right, and that Petrov really was a most determined and fearless man who recognized no restraint of any sort. Why I felt this I can’t explain either.
