Welcome to Agatha Christie: Murder on the Orient Express forum

Read Poirot's instructions in your journal regularly.
The primary trigger for the avalanche is listening at every carriage door with a glass.

Thought I had, but thanks so much for the tip. Will try again.

Hey, great! I HAD missed a door in the whiteout. This has been the most frustrating fun so far and it's just getting better! Of course, being the age I am (which I won't tell) and having begun reading Agatha Christie at my mother's knee, I'll never give up! We march! Thanks again.
