Desert Survival Story - Fiction - Man vs Man

Hi. I read this book when I was young (around 12 or so) and I remember being fascinated with it. I remember that one man was being hunted by another for whatever reason. Well call them the hunter and the hunted. The story mainly takes place in the desert if i'm not mistaken.

The end of the book takes place in a courtroom where the hunted proves the hunter tried to kill him. I really do not remember much but there is a part towards the end where the hunter has the hunted pinned in a mountain (or cave of some sort) with a sniper rifle. The hunted eventually gets shot and then proceeds to bury himself in the sand and waits to take down the hunter when he goes in for him to check for the kill.

Also I remember the book was a small hardcover with a white cover of some sort if that helps any :p. It really was a great book, and I am interested in reading it again. Hopefully someone knows what it is. Thanks!!

Approximately in what year were you twelve?

And this title you are searching for was a novel and not a short story? It has enough similarities to the very classic hunter vs. hunter short story The Most Dangerous Game (1924) to make me think they might have appeared in a same anthology together. ("The Most Dangerous Game" has no courtroom scene and takes place on a tropical island, not a desert, and has a decidedly different ending to what you described.)

Some lists of works with the hunter vs. hunted element are available on TV Tropes and Wikipedia.

Deathwatch, by Robb White, a classic.

Thanks for the responses.
It is indeed Deathwatch thank you very much!!! Much appreciated
