The last letter my mother wrote to me contained good news.

But he was the first to understand what the letter contained.

Never had she felt such a one as this letter contained.

It is not known what this letter might have contained.

Obviously, I need more information than one letter could possibly contain.

But I give the family an outline of the information the letter should contain.

For example, the letter contains information about the particular project and/or due dates.

The letter was to her, and contained his proposal of marriage.

However, the letter contained information that only the killer could have known, he said.

Their letters for a time contained no suggestion of politics.
