THE WISDOM OF FATHER BROWN
of fainter noises—as he counted them, about six. He supposed it must be the echo; but the odd thing was that the echo was not in the least like the original sound. It was not like anything else that he could think of; the three things nearest to it seemed to be the noise made by siphons of soda-water, one of the many noises made by an animal, and the noise made by a person attempting to conceal laughter. None of which seemed to make much sense.
Father Brown was made of two men. There was a man of action, who was as modest as a primrose and as punctual as a clock; who went his small round of duties and never dreamed of altering it. There was also a man of reflection, who was much simpler but much stronger, who could not easily be stopped; whose thought was always (in the only intelligent sense of the words) free thought. He could not help, even unconsciously, asking himself all the questions that there were to be asked, and answering as many of them as he could; all that went on like his breathing or circulation. But he never consciously carried his actions outside the sphere of his own duty; and in this case the two attitudes were aptly tested. He was just about to resume his trudge in the twilight, telling himself it was no affair of his, but instinctively twisting and untwisting twenty theories about what the odd noises might mean.
