'the reader doesn't even need to guess, he already knows how it's gonna end' Kind of the point really, there is no twist because there doesnt need to be, the man murdered Atwell and the dog avenged his master, end of, moral, bad people get there commupence. Seriously people do need to look at thereselves as 'lovers' of writing if they always need a surprise ending, the surprise was that there was no twist, you as the reader much like Fleming knew he was going to be killed. Not Bierce's best work but still better written than many other stories
