More frozen CO2? It melted and suffocated him?

502

The room was perfectly safe when his hosts left him for the night.

Or: no. :slight_smile:

503

**A man was traveling from Switzerland to his home in France by train. If he had been in a non-smoking car he would have died. Why? **

504

Hey, man!

505

LHOD:
Was the man poisoned?
Did he have any visible wounds when the body was discovered?
Did he inadvertently bring anything dangerous into the room with him?

Mahaloth:
Did anyone else on the train die?
Was the train itself damaged in any way?
Are the windows on the train relevant?

506
  1. Yes
  2. No
  3. No
507

Sorry!! I’ll wait. My bad.

508

Let’s do one at a time. I’ll answer this after we finish the current one that I obviously didn’t see on the last page. :slight_smile:

509

His lover killed him.

**Did his lover poison him before he got to the house where he stayed?

Was he poisoned at dinner that night?

Was the poison taken in by food?**

510
  1. was the lover human?
  2. is the New Year’s Eve time frame critical, or could this have happened any old night?
  3. was the door locked from the inside, as suggested by the narrative or is there something peculiar about the way the door locks?
  4. does the room have a chimney?
511
  1. No.
  2. No.
  3. No.
  1. Can you rephrase this question?
  2. Yes.
  3. Yes.
  4. Yes–but it’s blocked.

One more note, which may work as a hint: I got this puzzle from a Games Magazine a few decades ago. I’ve spent a bit of time Googling to make sure this murder method could work, and I’ve not come up with anything certain one way or another.

512

  1. Is everyone in this story a human being?

  2. Is the fact it is New Year’s Eve relevant?

  3. Could this have happened any other night?

  4. Was the poison breathed in?

513

Did the murder method involve a new year’s kiss?

514

1: Did he drink champagne on New Year’s Eve?
2. If so, was the champagne positioned?
3. Was the psycho ex at the NYE party?

515
  1. Yes (and above when I asked about rephrasing the question, I meant to ask this about the New Year’s question, not the human question. Sorry!)
  2. Yes
  3. Yes, if you mean it could have happened on other nights. Unlikely, if you mean it could have happened on any random night.
  4. Yes

No

  1. No
  2. No
  3. No
516

Was poison gas pumped into the room?

Were fireworks involved in this murder?

Was the chimney blocked to keep poison gas in?

517
  1. …I’m gonna say “yes.”
  2. No
  3. No

With that, I’m off to bed; I’ll check in tomorrow morning!

518

My recap, which could be wrong. Please check.

On New Year’s Eve, which is relevant, a poisonous gas was pumped into a locked room and killed a guy. His lover, who was not there, did it(or arranged it).

So we have to figure out:

  • how NY Eve plays into this situation
  • how his lover managed to get gas into the room
519

Would anyone else who had been in the room also have died?

Was the victim poisoned at midnight?

520

[chemistry nitpick]
Maybe he died of the bends? The room would have to be at more than 5 atmospheres for frozen CO2 to melt. At normal atmospheric pressure it would sublime (go directly from solid to gas.)
