Somewhere a plank creaked beneath the foot of whatever was walking, and the sound seemed to snap the last cord of sanity in the poor old man. With a roar like that of a maddened bull he released his grip on me and made a plunge to the right, through the open door of a room which I judged had been a parlour. A second later, just as I got the front door open and was making my own escape, I heard the tinkling clatter of broken glass and knew he had leapt through a window. And as I bounded off the sagging porch to commence my mad race down the long, weed-grown drive I thought I could catch the thud of dead, dogged footsteps which did not follow me, but which kept leadenly on through the door of the cobwebbed parlour.
