On what page of Fitzgerald's The Great Gatsby does Tom tell Wilson that Gatsby was the one who killed Myrtle?

We do not have a page number for this because we do not see the scene in which Tom tells Wilson who was driving the car, or at least, who he thinks was driving the car.  We learn from Nick almost at the end of the story that Tom told Wilson when Nick asks him directly.  He claims that Wilson came to their house while they were preparing to leave and threatened to force his way in. He had a gun. It is at this point that he told Wilson that it was Gatsby's car.  Speaking of Gatsby, he says, "'That fellow had it coming to him.... He ran over Myrtle like you'd run over a dog...'" (187).  In spite of Tom's responsibility in all of this, Nick shakes hands with him, realizing that Tom and Daisy and their kind were not capable of being any other than what they were, so it was pointless to try to change them. It is very shortly after this that Nick leaves to go back to the midwest, a sadder but wiser man.
