What action does Victor take? What is the result?

Unable to tolerate the shock, he collapses.

When he revives, he finds himself surrounded by the people of the inn; he escapes from them to the room in which Elizabeth's corpse is lying. He falls upon her body and takes it in his arms. Wracked by indescribable grief, he looks up to see the monster grinning at him through the windowpane. Victor fires his pistol, but the creature eludes him.

Frankenstein alerts the other guests of the murderer's presence, and they try in vain to apprehend him. Though he longs to aid them in their search, he is feeble as a result of his shock and misery; he is carried, barely conscious, to his bed. Realizing that he does not know whether his father and brother are safe, Victor gathers all of his strength and travels to Geneva. On the journey, he reflects that he has lost all hope of future happiness; no being in all creation is so miserable as he.
