What is the main theme of the story the open window

Vera tells Framton the tragedy of how Mrs. Sappleton's husband and brothers went hunting one day and never returned. Just after finishing this story, Mrs. Sappleton enters and apologizes for the open window, which is a set of French doors, and tells Framton that her husband and brothers will be returning soon.

Explanation:

his tongue, i believe, was bloody and hanging out of his mouth.

he looked as if he were hungry.

he has several wolf-like qualities; a gray coat, sharp claws and yellow fangs.

those eyes made me feel, dear reader, like the end was near.

as i reached for a stick, he moved to the other side of the hill.

panting and hungry, he looked at me, a defenseless human and he snarled.

well i said my prayers, however, he simply turned and limped off. 

there is no woman's sides

can bide the beating of so strong a passion

as love doth give my heart; no woman's heart

so big, to hold so much; they lack retention.

hope this !
