Stretton by Henry Kingsley

When Roland knocked at the door of Allan Gray, he had forgotten all about the great men he had seen, and all the things they had said. For he had received a very curious letter from Allan Gray, and he was thinking over it. The door was opened by Mrs. Gray, whom Roland knew. He was very polite to her, and he passed into the parlour on the right, where Allan Gray was sitting in state with papers on the table before him.

Allan Gray, less trained than Roland, bowed solemnly, and brought him to the fire. "Indeed, and it is cold to-night," said Roland. "A fire is a good thing, and in this instance it amounts to a personal obligation."
