And she did not like it.

She was not pleased that he was there.

She was less pleased that he blushed for being there.
It so happened that Alice found him there again several times.

Alice gave a piano lesson at two o'clock every Tuesday and Friday afternoon to a little Beacon Street neighbor of Billy's, and she had fallen into the habit of stepping in to see Billy for a few minutes afterward, which brought her there at a little past three, just after the chess lesson was well started.
If, the first time that Alice Greggory found Arkwright opposite Billy at the chess-table, she was surprised and displeased, the second and third times she was much more so.

When it finally came to her one day with sickening illumination, that always the tete-a-tetes were during Bertram's hour at the doctor's, she was appalled.
What could it mean?
Had Arkwright given up his fight?
Was he playing false to himself and to Bertram by trying thus, on the sly, to win the love of his friend's wife?
Was this man, whom she had so admired for his brave stand, and to whom all unasked she had given her heart's best love (more the pity of it!)--was this idol of hers to show feet of clay, after all?
She could not believe it.
