If, as
@Estelle suggests, B's father is every bit of a narc as B, he too would suffer from delusional illusions of grandeur, no? Narcissists are made, they are not born that way, so how did B get to be this way? I found it very strange that B went with his father in the days after C's death, to check out the property they bought. Who would do that when you're DIL has just been murdered by robbers? Wouldn't you be too grief stricken? Not B or his father, apparently. You may be right in that B himself made the calls, I don't know.
