sk, sir, how I come to have the honour of being your host?"
asked Faull sullenly. He thought that the evening was not proceeding as
smoothly as he had anticipated.

The newcomer looked at him for a second, and then broke into a great,
roaring guffaw. He thumped Faull on the back playfully--but the play was
rather rough, for the victim was sent staggering against the wall before
he could recover his balance.

"Good evening, my host!"

"And good evening to you too, my lad!" he went on, addressing the
supernatural youth, who was now beginning to wander about the room, in
apparent unconsciousness of his surroundings. "I have seen someone very
like you before, I think."

There was no response.

The intruder thrust his head almost up to the phantom's face. "You have
no right here, as you know."

The shape looked back at him with a smile full of significance, which,

encircled the soft, white neck of the materialised shape with his hairy
hands and, with a double turn, twisted it completely round. A faint,
unearthly shriek sounded, and the body fell in a heap to the floor. Its
face was uppermost. The guests were unutterably shocked to observe that
its expression had changed from the mysterious but fascinating smile
to a vulgar, sordid, bestial grin, which cast a cold shadow of moral
nastiness into every heart. The transformation was accompanied by a
sickening stench of the graveyard.

The features faded rapidly away, the body lost its consistence, passing
from the solid to the shadowy condition, and, before two minutes had
elapsed, the spirit-form had entirely disappeared.

The short stranger turned and confronted the party, with a long, loud
laugh, like nothing in nature.

The professor talked excitedly to Kent-Smith in low tones. Faull
beckoned Backhouse behind a wing of scenery, and handed him his check
without a word. The medium put it in his pocket, buttoned his coat, and
walked out of the room. Lang followed
