My remarks are, as always, apt, sound, and to the point. (Hercule Poirot)

Any medical man who predicts exactly when a patient will die, or exactly how long he will live, is bound to make a fool of himself. The human factor is always incalculable. The weak have often unexpected powers of resistance, the strong sometimes succumb.

I often wonder why the whole world is so prone to generalise. Generalisations are seldom if ever true and are usually utterly inaccurate.

Trains are wonderful.... To travel by train is to see nature and human beings, towns and churches and rivers, in fact, to see life.

The truth, however ugly in itself, is always curious and beautiful to seekers after it.
