"Evidently the vanishing qualities of the belt did not assert themselves very rapidly, Mr. Narkom," he said, "for Mr. Carboys not only prepared to go to bed, but had time to get himself ready to hurry off to business in the morning with as little delay as possible. Look here; here are his pyjamas on the top of this chest of drawers, neatly folded, just as he lifted them out of his portmanteau; and as a razor has been wiped on this towel (see this slim line of dust-like particles of hair), he shaved before going to bed in order to save himself the trouble of doing so in the morning. But as there is no shaving-mug visible, and he couldn't get hot water at that hour of the night, we shall probably discover a spirit-lamp and its equipment when we look into the portmanteau. Now, as he had time to put these shaving articles away after using, and as no man shaves with his collar and necktie on, if we do not find those, too, in the portmanteau, we may conclude that he put them on again; and, as he wouldn't put them on again if he were going to bed, the inference is obvious--something caused him to dress and prepare to leave the house voluntarily. That 'something' must have manifested itself very abruptly, and demanded great haste--either that, or he expected to return; for you will observe that, although he replaced his shaving tackle in the portmanteau, he did not put his sleeping-suit back with it. While I am poking about, do me the favour of looking in the bag, Mr. Narkom; and tell me if you find the collar and necktie there." "Not a trace of them," announced the superintendent a moment or two later. "Here are the shaving-mug, the brush, and the spirit-lamp, however, just as you suggested; and--Hallo! what have you stumbled upon now?" For Cleek, who had been "poking about," as he termed it, had suddenly stooped, picked up something, and was regarding it fixedly as it lay in the palm of his hand. "A somewhat remarkable thing to discover in a lady's bed-chamber, Mr. Narkom, unless--Just step downstairs, and ask Miss Morrison to come up again for a moment, will you?" And then held out his hand so that Narkom could see, in passing, that a hempseed, two grains of barley, and an oat lay upon his palm. "Miss Morrison," he inquired as Mary returned in company with the superintendent, "Miss Morrison, do you keep pigeons?" She gave a little cry, and clasped her hands together, as if reproaching herself for some heartless act. "Oh!" she said, moving hastily forward toward the window. "Poor dears! How good of you to remind me. To think that I should forget to feed them for three whole days. They may be dead by now. But at such a time I could think of nothing but this hideous mystery. My pigeons--my poor, pretty pigeons!" "Oh, then you do keep them?"
