In the introduction I mentioned below to Terror in the House:The Early Kuttner, Dr. Garyn G. Roberts says:
"Not unlike the twentieth century's master of Heroic Fantasy, Robert Erwin Howard, Kuttner died way too young."
Note that the good doctor didn't mention Howard's suicide, merely that he had died too young. None of the amateur psychology so many writers feel that they have to throw into any mention of REH's death. No groundless speculation on the motive for his suicide. Just a plain and simple statement. That's something we need to see more of. Thank you, Dr. Roberts.
