The Dark Man (first published in Weird Tales, December 1931) - Turlogh tries to rescues the daughter of King Brian Boru from a tribe of Vikings. This story features a cameo of another Howard character, Bran Mak Morn. It was also adapted as a Conan story by Marvel Comics. Howard earned $85.00 for the story.

The story was first accepted for Strange Stories, a planned companion magazine to Weird Tales. This is also the first story about Turlogh Dubh O'Brien. We learn of this in a letter (#124) to Tevis Clyde Smith, circa March 1930:

Well, Farnsworth said he was going to use “Shadows on the Road” as a full page rhyme in the issue after next. I wish he’d have it illustrated but I think they quit illustrating rhymes. Well, I’m not kicking; that’s about the quickest action I ever got on anything, for I sold it to him just recently. And he accepted a story for the new magazine. “The Dark Man” is the name of the tale and he promised me $85.00 on publication. The editor was kind enough to say it was a “red blooded, he-man story”. Well, it has plenty of gore and action. And incidently, I have created a new character to join Kull, Solomon Kane and Steve Costigan. His name is Turlogh Dubh O’Brien and I hope to have a series of stories dealing with him in the new magazine. This story, was, of course, about him. He is an Irish outlaw whose adventures are laid in the half century preceding the battle of Hastings. That’s a period teeming with intrigue, war and battles and I ought to be able to spin dozens of yarns about it.

He also wrote a letter (#145) to H.P. Lovecraft, circa November 1930:

Mr. Wright tells me that the issuing of Strange Stories is being delayed because of Macfadden’s disputing the right to the title. Several months ago he accepted a couple of my tales for the magazine, one of them dealing with the Bran cult, and I would like to see the publication on the newsstands.

And in a letter (#194) we learn why the story wasn't published in Strange Stories, but in Weird Tales. The letter was to Kirk Mashburn, circa March 1932:

I am writing to express my appreciation for your remarks concerning “The Dark Man”, in the Eyrie of the current copy of Weird Tales. You expressed my own ideas on the matter exactly. While “The Dark Man” was not originally written for Weird Tales, but for the planned Strange Stories, which was never published, it always seemed to me that it contained enough weird touches to justify its presence in the former magazine. Thanks for coming to its defense.

There was also some negative feedback on the story. A letter from Paul S. Smith appeared in The Eyrie, in February 1932, complaining that The Dark Man was "not the least bit weird":

"I have never before written you a word of adverse criticism," writes Paul S. Smith, of Orange, New Jersey, "because I know that you are trying to put out good a magazine as you can and because as he tries to please every one, an editor's as life sometimes, like a policeman's, is not a happy one. But there are three stories in the December issue on which I must offer some non-commendatory statements. The Dark Man is an adventure story pure and simple, and is best suited to a magazine like 'Adventure.' It is well written and contains a superabundance of fighting and bloodshed for those who like these things, but it is not the least bit weird. However, many of your readers will like it—so that's that. Dead Man's Vengeance is an excellent Western story and its proper place would be in a Western story magazine. The touches of weirdness it contains are so slight that I honestly believe it is too mild for your magazine, Bitter Gold is a very fine little story and I am glad to have read it. This tale is grim and tragic but not weird. Here are three stories in one issue, not one of which is genuinely weird. Fie, fie, sir! Is not WEIRD TALES to be kept weird? "

In another letter (#210) which Howard wrote to Tevis Clyde Smith, very late in May 1932:

The yammerings and droolings of Paul S. Smith of Orange and his breed begin to bear fruit; Farnsworth rejected four out of the last six stories I sent him, and almost invariably the reason was given as not weird enough.
