Johnstone of the Border by Harold Bindloss

Staffer and Williamson sat in the library at Appleyard. It was getting late, and the rest of the household were in bed. Williamson had gone to his room with the others, but afterward had crept down again quietly. He had arrived that evening, but had found it difficult to get any private conversation with his host without making his wish to do so rather marked; for he imagined that Miss Woodhouse was watching him; and Whitney was constantly about. Now, however, he had said all he thought needful, and he wondered why Staffer did not let him go.

The library was spacious and was lighted only by a shaded lamp on a table near them. The polished floor gleamed like ice in the illuminated circle, but everything outside this was dim, and Staffer's face was in the shadow. The fire in the big hearth had sunk, and a pale-blue flame that gave no light played about the embers of the hardwood logs. The room was very quiet and getting cold.
