(Super-Mystery Comics v1 003, 1940)
This is a bit of a weird one. Vulcan, the Volcanic Man, has just saved both a field of gasoline tanks and a government arson inspector named Grace Horner from being incinerated by "notorious arsonist-spy" Torchy Fargo, who then retires to a nearby castle* to report his failure to Ember, the Empress of Fire. Just what is the deal with these two, you ask? We shall explore that momentarily.
*Vulcan is plausibly based out of New York City, so this is another location in the Castle District of the Northeastern United States.
Ember decides to deal with both Vulcan and Horner by the simple expedient of inviting them to her castle. It's a simple trick, but an effective one.
Ember first tries to kill Vulcan by dumping a bunch of gunpowder on him and then setting him on fire and then, once he proves to be as fireproof as his name might imply, she decides to recruit him to the cause. Why together they could dump gunpowder on entire nations and set them alight!
Sadly for Ember, Vulcan does not want to become her Emperor of Fire and so declines her offer. Stung, she dumps him and Grace into a standard-issue super-villain's death pit to rot or possibly be subjected to further deathtraps. And this is where things take a turn - everything up until now has been within the normal bounds of what on might expect in a super-hero comic: a spy who specializes in arson reports to some sort of fire-themed... cult leader? living in a castle staffed by ersatz Pacific Islanders. Regular stuff, like I said.
But then, Torchy Fargo tosses Ember down into the hole as well, because he is the real head of the (fake?) fire cult and he heard her say that she would replace him with Vulcan. Ember was just a figurehead who let the power go to her head, as she says.
But... what the hell was this arrangement? Ember isn't going on television to claim responsibility for Torchy's crimes or acting as a go-between with people looking to contract his services. Heck, the government already knew about Torchy because that's why Grace Horner was on his tail! So just why was Torchy going back to a castle filled with (fake?) fire cultists and reporting to a fake superior in a bikini top every night?
I'm going to deploy this carefully, because there are certain comic book theories and observations that are usually only trotted out by the intellectually tedious, but I think that this might have been a sex thing. We don't need to explore it further, it's just the conclusion that most fits the evidence at hand.
But speaking of sex things, as in gender, a thing happens at the end of this comic that I have noticed a fair few times in the first three issues of Super-Mystery Comics, as having brought Torchy Fargo to justice via a massive gas explosion, Vulcan just lets Ember go so that she can "devote the rest of [her] life to serving humanity." Did Ace Magazines hold the official position that women can not truly be evil? The evidence is mounting that they might have!
