What would framton feel if he saw the hunter's scene from the window?

The three men have been out shooting birds. Vera sets Framton Nuttel up to believe that they are ghosts when he sees them returning out of the gathering dusk and heading towards the open window. But he wouldn't be quite as terrified by these figures if he thought they were only ghosts. What gives the ghost story an additional "turn of the screw," to borrow from Henry James, is that these three "ghosts" are all carrying guns. The guns present more of a threat than the ghosts. What could the ghosts do to him if they were not armed? They don't even know him. They have nothing against him. They are simply coming home for tea. It is the fact that they are avid hunters that makes Vera's ghost story so effective. They are carrying shotguns because they have been out shooting, and it is the fact that they have guns, rather than the fact that they seem to be ghosts, what makes them so terrifying to poor Framton Nuttel. He feels he has to run for his life and keep on running because he needs to cover a long distance before he will be safely out of shotgun range.
