Read it through once

"There's nothing to thank me for, Monsieur: it is I, rather--" M. Rivière broke off, as if speech for him too were difficult. "I should like, though," he continued in a firmer voice, "to add one thing. You asked me if I was in Count Olenski's employ. I am at this moment: I returned to him, a few months ago, for reasons of private necessity such as may happen to any one who has persons, ill and older persons, dependent on him. But from the moment that I have taken the step of coming here to say these things to you I consider myself discharged, and I shall tell him so on my return, and give him the reasons. That's all, Monsieur."
