Carnac not wanting the kerosene to get on the clothes was odd.
1. Wouldn't the kerosene burn first?
2. Wouldn't a body riddled with bullets make the police suspect foul play?
On my first read through the story, I was
also scratching my head as I tried to figure out the logic behind his insistence upon
not pouring kerosene directly onto the bodies he was planning to burn anyway. I wasn't thinking so much about the bullets, although it's a fair point -- those metal slugs in Sergeant Roach's corpse were bound to be noticed during the eventual autopsy unless the pathologist was
blind. (Maybe Carnac was hoping someone would think the two men had killed each other and no third party had been involved?)
Anyway, on the first pass, I was thinking more along these lines:
"Okay, Carnac, so you're
smart enough to anticipate that traces of kerosene may well be found by chemical analysis when the smoldering remains of this garage are investigated by the local authorities. But you think the cops
won't find anything terribly suspicious about the place having been splashed with kerosene -- as long as none of that kerosene had saturated the
clothes of the people you're leaving to burn? Guess what, buddy? My money says that the final verdict would still be 'deliberate arson,' rather than writing it off as a freak accident!"
Not sure why Hugh bothers with the secret identity as he was very cavalier with it at the end, but maybe it's just this story and others have him be more careful?
I was wondering about that, too. Like you, I know nothing about any of his other published cases, but I've noticed a similar odd pattern in some of the other Golden Age stuff I've read in the last few years -- cases where the hero of the story seems to fit all the following parameters:
1. He lives a double life.
2. In his "secret identity," he is a cop, secret agent, private investigator, or something similar, who has been ordered (or hired on a freelance basis) to take a professional interest in a certain mysterious case.
2. In his "costumed identity," he likewise takes a strong interest in that same case. Sometimes he peeps through windows or asks people questions in one role, and sometimes in the other, during the same investigation.
3. He has no genuine superpowers which he is trying to keep under wraps, meaning that in theory he's capable of doing the same things in either role without blowing his cover. Punching, shooting, interviewing, whatever. (As opposed to the way Clark Kent, for instance, quite understandably feels it would be a bad thing for everybody to realize he had all the powers of "Superman." He'd no longer be able to have a "normal" social life.)
4. So it often becomes very hard for us readers to understand where the hero draws the line between "I'd better pursue this next stage of the investigation as
Hugh Standish [or whomever]" and "I'd better pursue this next stage of the investigation as
The Grey Domino [or whomever]." Why can't the hero just use one identity all the way through, thereby keeping his life much simpler while (presumably) still learning the same interesting facts and arresting the same bad guys when he has sufficient grounds? Not to mention that this approach would make it much easier to write an accurate report to file with his boss or his client afterwards, if our hero didn't have to edit out half of his own in order to hide the fact that he did that half of the stuff that solved the case while he was wearing a mask?
P.S. Alternately, such a hero could wear his mask
100 percent of the time. Will Eisner's "The Spirit" springs to mind -- he seems to have felt that letting his original identity of "Denny Colt" stay alive would just cramp his style, but I occasionally wondered how much difference it really made since he no longer had any sort of "private life" as Denny Colt anyway, so what was he really hiding? How much good did it do him to wear a mask every minute of the day? Any time he walked down the street in broad daylight, he was wearing the same mask, and thus was a good target for any bad guys with a score to settle.
