In VN’s novel Transparent Things (1972) Mr. R.’s publisher receives Mr. R.’s last letter on the day of Mr. R.’s death:
Dear Phil,
This, no doubt, is my last letter to you. I am leaving you. I am leaving you for another even greater Publisher. In that House I shall be proofread by cherubim - or misprinted by devils, depending on the department my poor soul is assigned to. So adieu, dear friend, and may your heir auction this off most profitably.
