The word “hackneyed” here means “used by so, so many writers that by the time Lemony Snicket uses it, it is a tiresome cliché.” “Meanwhile, back at the ranch” is a phrase used to link what is going on in one part of the story to what is going on in another part of the story, and it has nothing to do with cows or with horses or with any people who work in rural areas where ranches are, or even with ranch dressing, which is creamy and put on salads.
