In Chapter 7 of Frankenstein, Victor is beckoned home after the death of William by his father's letter that asks him to return to console Elizabeth. As he arrives near Geneva, Victor decides to visit the spot where William was murdered; however a "tempest, so beautiful yet terrific" arrests his progress. Suddenly, a flash of lightning illuminates the figure of the creature Victor has created; Victor considers pursuit, but with another flash he can see
him hanging among the rocks of the nearly perpendicular ascent of Mont Saleve.
As Victor watches the creature scale these precipices, he realizes that it would be impossible for him to pursue his creation. For Victor Frankenstein, this mountain is inaccessible.
Who could arrest a creature capable of scaling the overhanging sides of Mont Saleve? These reflections determined me, and I resolved to remain silent.
Victor concludes that the strange nature of his creature would elude any pursuit made, even if he could persuade his relatives to make the attempt. This conclusion is part fact and part rationalization on Victor's part since he does not wish to reveal his act of creation to his family.
