The first word spoken to her in the train, before it reached Dover, had explained something of this to her.

She had felt at once that there would be trouble about money.
And now, though she did not at all understand what might be the nature of those troubles, though she had derived no information whatever from her husband's hints about the South American trade, though she was as ignorant as ever of his affairs, yet she felt that the troubles would come soon.

But never for a moment did it seem to her that he had been unjust in bringing her into troubled waters.
They had loved each other, and therefore, whatever might be the troubles, it was right that they should marry each other.

There was not a spark of anger against him in her bosom;--but she was unhappy.
He demanded from her the writing of the letter almost immediately after the conversation which has been given above, and of course the letter was written,--written and recopied, for the paragraph about the money was, of course, at last of his wording.

And she could not make the remainder of the letter pleasant.
