What is the summary of "The Ambitious Guest" by Nathaniel Hawthorne?

This story begins cozily enough, with a family gathered around a fire, harsh winter weather raging outside, and the vibe of possible danger, as their cottage is perched below a mountain down which stones frequently slide, startling everyone.  A traveler coming through the area is keeping company with them, and the family, content enough on the outside, begins to reveal bits of pieces of discontent in their individual lives.  When the dangerous sounds of a landslide can be heard, the family and their guest rush outside to avoid the danger, but ironically enough running right into the danger, while their cottage remains intact.
