of the vaulting descended to earth in the form of thick, heavy, crudely-carved, round-capitalled pillars. Mrs. Bradley suddenly disappeared behind one of these, and the inspector, thinking to follow, discovered that she was gone. Unpardonably, since the place must at one time have been consecrated, he swore nervously, and turned round to speak to the sergeant.
"Disappearing trick," he said, introducing a regrettable adjective.
"Snatched away ... and no wonder, with a physog like that," said the sergeant. Suddenly Mrs. Bradley's voice spoke right in his ear.
"Tell the inspector to mind the step," she said. The flight of stone steps was immediately visible to the sergeant. He blushed—fortunately in the darkness—and followed the inspector up to a little square trap-door.
"So if the one entrance or exit was not feasible or available, the other was," Mrs. Bradley explained, as the three of them emerged at the foot of the servants' staircase. "This passage, you see, is to the kitchen and scullery, and from the scullery the door opens almost on to the top of the well. The well is a good deal later in date than the crypt, of course, and may have existed independently of it for a hundred years or so. I know very little about such things, but I should put the date of the crypt as not much later than 1090. The well may have been sunk in the fifteenth century, and the passage connecting the two I should be inclined to associate with Tudor times, although I have nothing much to go on apart from the type of brickwork. I should think the connection was made to give protection to a Catholic priest. The Jesuits, I believe, were active towards the close of the sixteenth century.
"Anyhow, that's how the poltergeist worked. He could always be somewhere else—the essence of a good game of hide and seek. Let us return to the cellars. I have more to show you."
It was, the sergeant declared afterwards, as good as a film. They returned to the cellar by the way that they had used to ascend to the kitchen passage. A short length of linoleum had been removed to give free access to the trap-door.
"Accounts for the cold that people have noticed, I daresay," the inspector remarked, peering into the aperture which the open trap-door disclosed.
"And yet how necessary an adjunct to the presence of the supernatural," said Mrs. Bradley.* "There is a way into this passage from the back stairs," she added. "You will have noticed that the back stairs have no doors."
*"Such cold air currents, or psychic winds, have been experienced, we should add, with many mediums....

The inspector could not see that this had anything to do with it, and said so, but received no answer except an accidental dig in the back from the sergeant who, at Mrs. Bradley's request, had provided himself with one of the crowbars which the police had brought with them in their car.
Upon reaching the cellar (or crypt, as Mrs. Bradley preferred to call it), they examined the floor with great care, but for some time could find no indication of anything out of the ordinary except a slight depression near the well-side entrance, which was to the west. The wall on this side was extremely damp, and the sergeant twice stepped into a pool of water before it occurred to him or to the inspector to enquire why there was water on the floor in this spot.
"Must be a depression, and fills from the well," he said. He climbed up the well again as the nearest way back to the house, and procured a birch broom which he brought back by way of the inside staircase. When he had swept away the water the cause of the sinking still was not apparent, but by testing the bricks with the crowbar he discovered that they were loose and could be prised up. Whilst they were being moved, however, a rush of water filled up each hole as it was made.
"Put 'em back," said the inspector, helping in this part of the work. "I'd say you've given us enough to go on, ma'am," he added, when the three of them were in the house once more, "and I'm inclined to pass on the information so that we can get our hooks on the lady before she makes a getaway.
