"And he compelled Sir Hugh to take you to his consulting room, eh? Under what pretext?"

"I was suffering from extreme nervousness, and he prescribed for me with beneficial effect," she said. "But ever since I have felt myself beneath his influence in a manner which I am utterly unable to describe. I do not believe in hypnotic suggestion, or it might be put down to that."

"But what is your theory?"

"I have none, except—well, except that this man, essentially a man of evil, possesses some occult influence which other men do not possess."

"Yours is not a weak nature, Enid," he declared. "You are not the sort of girl to fall beneath the influence of another."

"I think not," she laughed in reply. "And yet the truth is a hard and bitter one."

"Remain firm and determined to be mistress of your own actions," he urged, "and in the meantime I will cultivate the doctor's acquaintance and endeavour to investigate the cause of this remarkable influence of his."

Why did Doctor Weirmarsh possess such power over Sir Hugh? he wondered. Could it be that this man was actually in possession of the truth? Was he aware of that same terrible and hideous secret of which he himself was aware—a secret which, if exposed, would convulse the whole country, so shameful and scandalous was it!

He saw how pale and agitated Enid was. She had in her frantic anxiety sought his aid. Only a few days ago they had parted; yet now, in the moment of her fear and apprehension, she had recalled him to her side to seek his advice and protection.

She had not told him of that mysterious warning Weirmarsh had given her concerning him, or of his accurate knowledge of their acquaintanceship. She had purposely refrained from telling him this lest her words should unduly prejudice him. She had warned Walter that the doctor was his enemy—this, surely, was sufficient!
