Why is Watson feeling increasingly I'll at ease?

Watson's diary is specific about what is troubling him. Watson almost believes in the hound. Though the diary acknowledges that such a belief strains his rationality, he also admits the "facts" of the howling, and acknowledges the difficulties posed even if there were an actual hound (245). For instance, the hound would need to be fed.   Watson then considers the mystery of the bearded man in London, noting that he has seen no one resembling that figure out on the moor. He decided to concentrate on this problem, hoping it would open doors to some of the other mysteries.  You can always visit the GradeSaver site for more.
