What is the point of view of "The Destructors"?
Your original question stated that the point of view used in this great short story was limited third person. However, actually, the point of view utilised is the omniscient narrator. The limited third-person narration only tells the story from the perspective of one person who the narrator focuses on to narrate the tale - we gain access to their thinking and motivation. However, it is clear that in "The Destructors" Greene adopts the omniscient narrator, which means that he acts as a God-like, all-knowing narrator, who can focus on any character and reveal what is going on through their eyes. For example, at times Greene zooms in on "Old Misery":
He didn't want to soil his house, which stood jagged and dark between the bomb sites, saved so narrowly, he believed, from destruction.
And at others we get access into the mind of other characters, such as Blackie:
...Blackie was dimly aware of the fickleness of favour. He thought of going home, of never returning, of letting them all discover the hollowness of T.'s leadership...
Clearly therefore, any narrative that is written in the third person that presents us with the thoughts and perspective of more than one character can be described as adopting the omniscient point of view.
