"From the little that I have seen of you it appears to me, Dr. Hardacre," said he, "that you are the very man I have wanted to meet."

"I am delighted to hear it, sir."

"Your head seems to be cool and steady. You will acquit me of any desire to flatter you, for the circumstances are too serious to permit of insincerities. You have some special knowledge upon these subjects, and you evidently view them from that philosophical standpoint which robs them of all vulgar terror. I presume that the sight of an apparition would not seriously discompose you?"

"I think not, sir."

"Would even interest you, perhaps?"

"Most intensely."

"As a psychical observer, you would probably investigate it in as impersonal a fashion as an astronomer investigates a wandering comet?"

"Precisely."

He gave a heavy sigh.

"Believe me, Dr. Hardacre, there was a time when I could have spoken as you do now. My nerve was a by-word in India. Even the Mutiny never shook it for an instant. And yet you see what I am reduced to—the most timorous man, perhaps, in all this county of Wiltshire. Do not speak too bravely upon this subject, or you may find yourself subjected to as long-drawn a test as I am—a test which can only end in the madhouse or the grave."
