I hurried off to look for the post-runner, but he had started back an hour before.

There was nothing for it but to wait on the coming of the unknown.
That afternoon I again took Mr Wardlaw for a walk.

It is an ingrained habit of mine that I never tell anyone more of a business than is practically necessary.

For months I had kept all my knowledge to myself, and breathed not a word to a soul.

But I thought it my duty to tell Wardlaw about the letter, to let him see that we were not forgotten.
