The Case of Charles Dexter Ward
"An H. P. Lovecraft Encyclopedia" doesn't mention anything about the chronology of "The Case of Charles Dexter Ward" or "Out of the Aeons". Lovecraft scholar S.T. Joshi used the chronology Lovecraft gives in "The Silver Key" in which the events in "The Statement of Randolph Carter" took place when Carter was in his late forties. Joshi says it would also explain why he was called a "bag of nerves" in that story, since it took place after his World War I service in which he was nearly killed and might still have post-traumatic stress disorder.
