The letter to which the following is an answer has not been found.

I even found a letter from the college waiting for me.

He'd never have let that letter be found if so.

Early in the fall he found a letter waiting for him there.

Then, one evening, he found a letter waiting for him at home.

Well and good, all will be if the letter is found in his coat.

Later another letter was found inside a book addressed to her parents.

This letter, when opened, was found to be from some high officer.

He showed the letter found in it to the agent.

On the table they found a letter from his girlfriend saying she couldn't wait for three years.
