Roth Versus Trilling--and Remembering "When She Was Good"

NYRB Classics showcases a remarkable (unsent) letter in which Philip Roth gives a bit of what-for to Diana Trilling for what she said about Portnoy's Complaint (link, link). Good fun in its own right, but not least remarkable because it calls attention to an early Roth novel, now unjustly forgotten. That would be When She Was Good, which Roth himself obviously holds in esteem. I don't know anybody but me who still remembers it. I confess I haven't read all that much of the later Roth but this early one sticks in my mind more than Portnoy, more than Goodbye, Columbus.
