In chapter Seven of The Queen of Air and Darkness,  the second tome in  T. H. White's  Tetrology that retells  the King Arthur Saga in modern language, we find the four troubled  adolescent sons of  the sorceress Queen Morgause, Gawain, Agravaine, Gaheris, and Gareth,  vying for their mother's attention by attempting to surprise her with a special gift – a unicorn they set out to capture in the woods. It does not quite work out as planned.
