actions in frankenstein

I feel like in frankenstein the actions are more effective. I feel this way because they give more of an suspicious side to the story as well as bringing out the stories horror factors. When William is murdered it came out of no where and kinda surprised me. Then after that incident when Victor finds the monster and comes to the conclusion it gives the story another twist. When  Justine was killed it just made the story seem more brutal and gives it that horror factor that I spoke of earlier. The scene where Victor finds the monster and chases him to the cliff, and then suddenly the monster just disappears it makes the monster and the scene just feel eerie. I feel like the setting and details that shelly uses are very effective as well but I feel like the actions combined with her descriptions of the actions are more effective.
