详细说明：though I was — it is only right that you should know the fate of your abandoned mistress. When I have finished this letter it will be dark — the shadows are closing in already, and I can scarcely see to write. I shall creep quietly from the house, and shall make my way over to that river which I have crossed so often, seated by your side in a carriage. Once on the bridge, under cover of the blessed darkness, all my troubles will be ended; you will be burdened with me no longer, and I shall not cost you even the ten-pound note which you so generously left for me, and which I shall enclose in this letter. Forgive me if there is some bitterness in my heart. I try to forgive you — I do forgive you! May a merciful heaven pardon my sins, as I pardon your desertion of me! M.G.’”
