Mystery show had an episode about this. They assumed someone poisoned the wine, but testing came up empty. The killer pumped gas into the room. It was hours before anyone noticed the death, at which point the gas had dissipated.

I think they either overlooked the fact that it would make everyone else queasy as it circulated around the hotel, or they assumed a lot of it would leak out through the walls, which is not necessarily a good assumption.

There are some questions that need establishing: Was the person murdered? Was it intended for the dead person to die inside a locked room? Any medical complaints/treatments which could have lead to the person dying? Any cause to murder that person? If murdered the method used could indicate background of the murderer? When is a scenario/situation not just a phishing exercise for some other purpose?

Not familiar with the gas used in the Mystery show, but if it was nitrogen pumped into the victim's room, nobody in the rest of the hotel would have felt anything. Nitrogen is an excellent asphyxiant, with no sensible difference from air.

> There are so many moving parts in some of his stories that you want to put down the book and sit back in awe that Carr can handle all of them without dropping a single strand. I’m tempted to describe this as a quasi-mathematical skill, but Carr always proclaimed his absolute hatred of math (which he called “the last refuge of the halfwit”)—and there’s even an anecdote about him punching a friend simply because he had mentioned the word algebra.

> Sometimes I feel I need to construct a GANTT chart just to understand the explanation at the end of some of these novels.

LOL

Could this method even be detected in an Autopsy ?

How to commit a murder inside a locked room, off the top of my head: - Are the windows locked? Otherwise it's a rock climber who can climb the side of the building. Some buildings are not that difficult to climb for a good climber. - The murderer was not in the room when the murder happened. Poison or a trap of some sort. (Kinda boring.) - The murderer was in the room when the murder happened, but locked the door beh…

> The murderer is still inside the room, very well hidden. Say, inside the sofa where the stuffing should be, waiting very quietly until the investigation is over so they can leave. Not a murder, but this is essentially the resolution of a Spike Lee movie. (no name - no spoiler)

Ummm, I think it's probably spoiled from context and connection alone, right?

One way to think about the popularity of locked-room mysteries is to think about the popularity of knock-knock jokes, or any other joke with a similarly well-worn setup. Precisely because it's well-worn territory, the low-hanging fruit has all been picked, and the art is in coming up with a punchline that feels new or original. "The Mystery of the Yellow Room," published in 1908 and considered one of the best of its…

I liked The Mystery of the Yellow Room better than Carr's when I was going through a locked-door phase. It's written well and unlike many of the others, the solution is pretty logical. And it has the best "when you've eliminated the impossible, whatever remains, however improbable, must be the truth" moments as well. "Starting on the right side of reason," as Rouletabille (sp?) puts it.

I don't know. I doubt there would be any gross indicators (like petechiae incident to strangulation), but maybe there would be some subtle blood chemistry indicator.

Nitrogen asphyxiation is an occasional industrial cause of death. I haven't looked in to the post-mortem data.
