I've had a very strange, secret sort of a letter, Mr. Bates.

Even Peter Cheever had his in plenty, and of a peculiar secret sort.

It was the most secret sort of compact, and to divulge its ten stipulations would even now be most disastrous.

I wouldn't have believed it of you, running away in that secret sort of way and letting none of us know anything about you.

Secret sort of talk.
