When I first found you in the dining-room, I acted most improperly; I lost my temper.

I did worse; I was foolish enough and imprudent enough to send for a police officer.
I owe you every possible atonement (afflicted as you are) for treating you in that cruel manner.

I offered you the use of my boudoir, as part of my atonement.

I sent for you, in the hope that you would allow me to assist you, as part of my atonement.

You may behave rudely to me, you may speak in the most abusive terms of my adopted daughter; I will submit to anything, as part of my atonement.
