The Light of Western Stars by Zane Grey

In the cool, starry evenings the campers sat around a blazing fire and told and listened to stories thrillingly fitted to the dark crags and the wild solitude.

Monty Price had come to shine brilliantly as a storyteller. He was an atrocious liar, but this fact would not have been evident to his enthralled listeners if his cowboy comrades, in base jealousy, had not betrayed him. The truth about his remarkable fabrications, however, had not become known to Castleton, solely because of the Englishman's obtuseness. And there was another thing much stranger than this and quite as amusing. Dorothy Coombs knew Monty was a liar; but she was so fascinated by the glittering, basilisk eyes he riveted upon her, so taken in by his horrible tales of blood, that despite her knowledge she could not help believing them.
