Hercule Poirot, undercover:

Fortunately this queer little foreigner did not seem to know much English. Quite often he did not understand what you said to him, and when everyone was speaking more or less at once he seemed completely at sea. He appeared to be interested only in refugees and postwar conditions, and his vocabulary only included those subjects. Ordinary chit-chat appeared to bewilder him. More or less forgotten by all, Hercule Poirot leant back in his chair, sipped his coffee and observed, as a cat may observe the twitterings and comings and goings of a flock of birds. The cat is not ready yet to make its spring.
