Uther and Igraine by Warwick Deeping

Nothing is more chafing to the patience than to lie abed crippled, knowing the while that coveted hours are slipping through one's fingers like grains of gold. To Igraine, her maimed ankle was a very thorn in the flesh. Her thoughts were tugging to be at Sarum, and she was in continual fear lest Radamanth or Gorlois should track her to her temporary refuge, and attempt to mar her freedom. She was not a woman who could take hindrance with perfect philosophy, comforting herself with the reflection that care never yet salved unrest. She chafed at delay, and even blamed Eudol with great unreason because he had obliged her with a horse not proof against stumbling.

The knowledge that Gorlois rode in search of her did not tend to the easing of her mind. She began to understand Gorlois to the full. He had betrayed so much of himself in Radamanth's garden that her dread grew nearly as great as her disrelish.
