“Very good, Barrymore. We may talk further of this some other time.” When the butler had gone I walked over to the black window, and I looked through a blurred pane at the driving clouds and at the tossing outline of the wind-swept trees. It is a wild night indoors, and what must it be in a stone hut upon the moor. What passion of hatred can it be which leads a man to lurk in such a place at such a time! And what deep and earnest purpose can he have which calls for such a trial! There, in that hut upon the moor, seems to lie the very centre of that problem which has vexed me so sorely. I swear that another day shall not have passed before I have done all that man can do to reach the heart of the mystery.
