do u think hunters really have mud up to their eyes ?what does the aunt mean by this expression ? what effect does the author create by using exclamatory sentences here?

The imagery of figures covered up to their eyes in mud reinforces the story Vera tells about the men suffocating in a muddy bog. Before Framton turns to see the men the reader first hears the aunt’s observation of their approach. In order to maintain the trick until the very end, Saki employs imagery that contributes to an eerie, almost zombie-like vision of muddied bodies approaching so as not to give away the truth.
