“I will come,” said I.
“Then get your revolver and put on your boots. The sooner we start the better, as the fellow may put out his light and be off.”
In five minutes we were outside the door, starting upon our expedition. We hurried through the dark shrubbery, amid the dull moaning of the autumn wind and the rustle of the falling leaves. The night air was heavy with the smell of damp and decay. Now and again the moon peeped out for an instant, but clouds were driving over the face of the sky, and just as we came out on the moor a thin rain began to fall. The light still burned steadily in front.
“Are you armed?” I asked.
“I have a hunting-crop.”
“We must close in on him rapidly, for he is said to be a desperate fellow. We shall take him by surprise and have him at our mercy before he can resist.”
“I say, Watson,” said the baronet, “what would Holmes say to this? How about that hour of darkness in which the power of evil is exalted?”
As if in answer to his words there rose suddenly out of the vast gloom of the moor that strange cry which I had already heard upon the borders of the great Grimpen Mire. It came with the wind through the silence of the night, a long, deep mutter, then a rising howl, and then the sad moan in which it died away. Again and again it sounded, the whole air throbbing with it, strident, wild, and menacing. The baronet caught my sleeve and his face glimmered white through the darkness.
