Kilmeny of the Orchard by Lucy Maud Montgomery

Thenceforward Eric Marshall was a constant visitor at the Gordon homestead. He soon became a favourite with Thomas and Janet, especially the latter. He liked them both, discovering under all their outward peculiarities sterling worth and fitness of character. Thomas Gordon was surprisingly well read and could floor Eric any time in argument, once he became sufficiently warmed up to attain fluency of words. Eric hardly recognized him the first time he saw him thus animated. His bent form straightened, his sunken eyes flashed, his face flushed, his voice rang like a trumpet, and he poured out a flood of eloquence which swept Eric's smart, up-to-date arguments away like straws in the rush of a mountain torrent. Eric enjoyed his own defeat enormously, but Thomas Gordon was ashamed of being thus drawn out of himself, and for a week afterwards confined his remarks to "Yes" and "No," or, at the outside, to a brief statement that a change in the weather was brewing.

Janet never talked on matters of church and state; such she plainly considered to be far beyond a woman's province. But she listened with lurking interest in her eyes while Thomas and Eric pelted on each other with facts and statistics and opinions, and on the rare occasions when Eric scored a point she permitted herself a sly little smile at her brother's expense.
