“Presently, they left the Pentacle, and gathered ’round the living boarhound, which seemed curiously quiet, as though it were half-drugged.  There was some talk as to whether to let the poor brute live, or not; but finally they decided it would be good policy to kill it.  I saw two of them force a twisted loop of rope into its mouth, and the two bights of the loop were brought together at the back of the hound’s neck.  Then a third man thrust a thick walking-stick through the two loops.  The two men with the rope, stooped to hold the dog, so that I could not see what was done; but the poor beast gave a sudden awful howl, and immediately there was a repetition of the uncomfortable breaking sound, I had heard earlier in the night, as you will remember.

“The men stood up, and left the dog lying there, quiet enough now, as you may suppose.  For my part, I fully appreciated the calculated remorselessness which had decided upon the animal’s death, and the cold determination with which it had been afterward executed so neatly.  I guessed that a man who might get into the ‘light’ of those particular men, would be likely to come to quite as uncomfortable an ending.

“A minute later, one of the men called out to the rest that they should ‘shift the wires.’  One of the men came toward the doorway of the corridor in which I stood, and I ran quickly back into the darkness of the upper end.  I saw the man reach up, and take something from the top of the door, and I heard the slight, ringing jangle of steel wire.

“When he had gone, I ran back again, and saw the men passing, one after another, through an opening in the stairs, formed by one of the marble steps being raised.  When the last man had vanished, the slab that made the step was shut down, and there was not a sign of the secret door.  It was the seventh step from the bottom, as I took care to count:  and a splendid idea; for it was so solid that it did not ring hollow, even to a fairly heavy hammer, as I found later.

“There is little more to tell.  I got out of the house as quickly and quietly as possible, and back to the inn.  The police came without any coaxing, when they knew the ‘ghosts’ were normal flesh and blood.  We entered the park and the Manor in the same way that I had done.  Yet, when we tried to open the step, we failed, and had finally to smash it.  This must have warned the haunters; for when we descended to a secret room which we found at the end of a long and narrow passage in the thickness of the walls, we found no one.

“The police were horribly disgusted, as you can imagine; but for my part, I did not care either way.  I had ‘laid the ghost,’ as you might say, and that was what I set out to do.  I was not particularly afraid of being laughed at by the others; for they had all been thoroughly ’taken in’; and in the end, I had scored, without their help.
