point of view: character estranged?

[Albus Dumbledore]

To which work of literature are you referring? Do you mean
The Stranger by Albert Camus?
Generally speaking, the word "estranged" means alienated,
cut-off, separated from the rest of humanity either physically or more commonly, psychologically.

We often see the word in gossip columns in the tabloids
referring to a couple on the verge of divorce.

thanks for defining it, you are so kind
