From somewhere within the depths of the house, not very far from the room in which I was, there was a noise. It was a faint noise, and, strain my ears as I might, I could not make out exactly what it was. It was a sound like a regular yet intermittent bump or rumble. Nothing else happened. There were no footsteps, no creaking floorboards, the air was absolutely still, the wind did not moan through the windowpane. Only the muffled noise went on and my dog, Spider, continued to stand, bristling at the door, now putting her head at the gap on the bottom and snuffling around, now taking a pace backwards, head cocked and like me, listening. Every now and then, she growled again.
