I dedicate this Weekly Poirot post to my coworker who died last week. For as long as I knew her, she wisely avoided the headaches of highway traffic by taking the commuter train to work. Poirot had many things to say about trains, but this excerpt seems the most fitting for the occasion.
Life is like a train . . . . It goes on. And it is a good thing that that is so. . . . Because the train gets to its journey’s end at last, and . . . it is le bon Dieu who drives it.
from The Mystery of the Blue Train
