Lady Lashmore held a fan before her face.

"There have been recent happenings," she said--"as no doubt you are aware--which must have shaken anyone's nerves. Of course, I am familiar with your reputation, Dr. Cairn, as a psychical specialist--?"

"Pardon me, but from whom have you learnt of it?"

"From Mr. Ferrara," she answered simply. "He has a.s.sured me that you are the greatest living authority upon such matters."

Dr. Cairn turned his head aside.

"Ah!" he said grimly.

"And I want to ask you a question," continued Lady Lashmore. "Have you any idea, any idea at all respecting the cause of the wounds upon my husband's throat? Do you think them due to--something supernatural?"

Her voice shook, and her slight foreign accent became more marked.

"Nothing is supernatural," replied Dr. Cairn; "but I think they are due to something supernormal. I would suggest that possibly you have suffered from evil dreams recently?"

Lady Lashmore started wildly, and her eyes opened with a sort of sudden horror.

"How can you know?" she whispered. "How can you know! Oh, Dr. Cairn!"

She laid her hand upon his arm--"if you can prevent those dreams; if you can a.s.sure me that I shall never dream them again--!"

It was a plea and a confession. This was what had lain behind her coldness--this horror which she had not dared to confide in another.

"Tell me," he said gently. "You have dreamt these dreams twice?"

She nodded, wide-eyed with wonder for his knowledge.

"On the occasions of your husband's illnesses?"

"Yes, yes!"

"What did you dream?"

"Oh! can I, dare I tell you!--"

"You must."

There was pity in his voice.

"I dreamt that I lay in some very dark cavern. I could hear the sea booming, apparently over my head. But above all the noise a voice was audible, calling to me--not by name; I cannot explain in what way; but calling, calling imperatively. I seemed to be clothed but scantily, in some kind of ragged garments; and upon my knees I crawled toward the voice, through a place where there were other living things that crawled also--things with many legs and clammy bodies...."

She shuddered and choked down an hysterical sob that was half a laugh.

"My hair hung dishevelled about me and in some inexplicable way--oh!

am I going mad!--my head seemed to be detached from my living body! I was filled with a kind of unholy anger which I cannot describe. Also, I was consumed with thirst, and this thirst...."

"I think I understand," said Dr. Cairn quietly. "What followed?"

"An interval--quite blank--after which I dreamt again. Dr. Cairn, I _cannot_ tell you of the dreadful, the blasphemous and foul thoughts, that then possessed me! I found myself resisting--resisting--something, some power that was dragging me back to that foul cavern with my thirst unslaked! I was frenzied; I dare not name, I tremble to think, of the ideas which filled my mind. Then, again came a blank, and I awoke."

She sat trembling. Dr. Cairn noted that she avoided his gaze.

"You awoke," he said, "on the first occasion, to find that your husband had met with a strange and dangerous accident?"

"There was--something else."

Lady Lashmore's voice had become a tremulous whisper.

"Tell me; don't be afraid."

She looked up; her magnificent eyes were wild with horror.

"I believe you know!" she breathed. "Do you?"

Dr. Cairn nodded.

"And on the second occasion," he said, "you awoke earlier?"

Lady Lashmore slightly moved her head.

"The dream was identical?"

"Yes."

"Excepting these two occasions, you never dreamt it before?"

"I dreamt _part_ of it on several other occasions; or only remembered part of it on waking."

"Which part?"

"The first; that awful cavern--"

"And now, Lady Lashmore--you have recently been present at a spiritualistic _seance_."

She was past wondering at his power of inductive reasoning, and merely nodded.

"I suggest--I do not know--that the _seance_ was held under the auspices of Mr. Antony Ferrara, ostensibly for amus.e.m.e.nt."

Another affirmative nod answered him.

"You proved to be mediumistic?"

It was admitted.

"And now, Lady Lashmore"--Dr. Cairn's face was very stern--"I will trouble you no further."

He prepared to depart; when--
