Suspense by Joseph Conrad

Cosmo, ill at ease, remained looking at her. He was in doubt what the sign she had made meant, a nervous and imperious gesture, which might have been a command for him to go or to stay. In his irresolution he gazed at her, thinking that she was lovely to an incredible degree and that the word "radiant" applied to her extraordinary aptness. Light entered into her composition. And it was not the cold light of marble. "She actually glows," he said to himself, amazed, "like ripe fruit in the foliage, like a big flower in the shade."

"Don't gaze at my blushes," said Madame de Montevesso in an even tone tinged with a little mockery and a little bitterness. "Would you believe that when I was a girl I was so shy that I used to blush crimson whenever anybody looked at me or spoke to me? It's a failing which does not meet with much sympathy. And yet my suffering was very real. It would reach such a pitch at times that I was ready to cry."
