Agatha Christie - One must have common sense, nothing is permanent, nothing endures....

One must have common sense, nothing is permanent, nothing endures. I have come to the conclusion that this place is run by a madman. A madman, let me tell you, can be very logical. If you are rich and logical and also mad, you can succeed for a very long time in living out your illusion. But in the end.. In the end this will break up. Because, you see, it is not reasonable what happens here! That which is not reasonable must always pay the reckoning in the end.~Dr. Barron
