to be ignominiously checkmated from sheer inattention

Mrs. Walter Powell’s shallow-sighted blue eyes might behold in Lucy Captain Bulstrode’s attraction to the East Cliff, but Lucy herself knew better — bitterly, cruelly better. Captain Bulstrode’s attentions to Miss Lucy Floyd were most evident,” Mrs. Powell said one day when the captain left, after a long morning’s music, and singing, and chess. How Lucy hated the prim phrase! None knew so well as she the value of those “attentions.” They had been at Brighton six weeks, and for the last five the captain had been with them nearly every morning. He had ridden with them on the downs, and driven with them to the Dike, and lounged beside them listening to the band, and stood behind them in their box at the pretty little theatre, and crushed with them into the Pavilion to hear Grisi, and Mario, and Alboni, and poor Bosio. He had attended them through the whole round of Brighton amusements, and had never seemed weary of their companionship. But for all this, Lucy knew what the last leaf upon the rose would tell her when the many petals should be plucked away, and the poor stem be left bare. She knew how often he forgot to turn over the leaf in the Beethoven sonatas, how often he put streaks of green into a horizon that should have been purple, and touched up the trees in her foreground with rose-pink, and suffered himself to be ignominiously checkmated from sheer inattention, and gave her wandering, random answers when she spoke to him. She knew how restless he was when Aurora read Bell’s Life, and how the very crackle of the newspaper made him wince with nervous pain. She knew how tender he was of the purblind mastiff, how eager to be friends with him, how almost sycophantic in his attentions to the big, stately animal. Lucy knew, in short, that which Talbot as yet did not know himself — she knew that he was fast falling head over heels in love with her cousin, and she had, at the same time, a vague idea that he would much rather have fallen in love with herself, and that he was blindly struggling with the growing passion.
It was so; he was falling in love with Aurora. The more he protested against her, the more determinedly he exaggerated her follies, and argued with himself upon the folly of loving her, so much the more surely did he love her. The very battle he was fighting kept her for ever in his mind, until he grew the veriest slave of the lovely vision which he only evoked in order to endeavor to exorcise.
“How could he take her down to Bulstrode, and introduce her to his father and mother?” he thought; and at the thought she appeared to him illuminating the old Cornish mansion by the radiance of her beauty, fascinating his father, bewitching his mother, riding across the moorland on her thorough-bred mare, and driving all the parish mad with admiration of her.
