Abraham, a Servant, Rebecca, and Isaac (Gen 24)

David Frankel asks the following question.

Abraham tells his servant to go to his hometown to find a wife for Isaac. When the servant returns, he never reports back to him or introduces Rebecca to him. Why does Abraham disappear from the narrative? And, as Rebecca is his great-niece, why not send the servant to her father’s home directly?

I don't agree with some of the critical methodologies on display in answering the question but I found the discussion here interesting.
