FATHER BROWN was walking home from Mass on a white weird morning when the mists were slowly lifting–one of those mornings when the very element of light appears as something mysterious and new. The scattered trees outlined themselves more and more out of the vapour, as if they were first drawn in grey chalk and then in charcoal. At yet more distant intervals appeared the houses upon the broken fringe of the suburb; their outlines became clearer and clearer until he recognized many in which he had chance acquaintances, and many more the names of whose owners he knew. But all the windows and doors were sealed; none of the people were of the sort that would be up at such a time, or still less on such an errand. But as he passed under the shadow of one handsome villa with verandas and wide ornate gardens, he heard a noise that made him almost involuntarily stop. It was the unmistakable noise of a pistol or carbine or some light firearm discharged; but it was not this that puzzled him most. The first full noise was immediately followed by a series 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. Then the grey sky-line brightened into silver, and in the broadening light he realized that he had been to the house which belonged to an Anglo-Indian Major named Putnam; and that the Major had a native cook from Malta who was of his communion. He also began to remember that pistol-shots are sometimes serious things; accompanied with consequences with which he was legitimately concerned. He turned back and went in at the garden gate, making for the front door.
Half-way down one side of the house stood out a projection like a very low shed; it was, as he afterwards discovered, a large dustbin. Round the corner of this came a figure, at first a mere shadow in the haze, apparently bending and peering about. Then, coming nearer, it solidified into a figure that was, indeed, rather unusually solid. Major Putnam was a bald-headed, bull-necked man, short and very broad, with one of those rather apoplectic faces that are produced by a prolonged attempt to combine the oriental climate with the occidental luxuries. But the face was a good-humoured one, and even now, though evidently puzzled and inquisitive, wore a kind of innocent grin. He had a large palm-leaf hat on the back of his head (suggesting a halo that was by no means appropriate to the face), but otherwise he was clad only in a very vivid suit of striped scarlet and yellow pyjamas; which, though glowing enough to behold, must have been, on a fresh morning, pretty chilly to wear. He had evidently come out of his house in a hurry, and the priest was not surprised when he called out without further ceremony: “Did you hear that noise?”
