Answer:
- “To me, who knew his every mood and habit, his attitude and manner told their own story. He was at work again.” (paragraph 1)
- “His manner was not effusive. It seldom was; but he was glad, I think, to see me.” (paragraph 2)

In the second line, Watson was able to deduce that Holmes was glad to see him even though his manner was not revealing this.

"Keep," this is because the adverb always modifies the verb, and a verb is a action, and keeping is an action.
