“H’m,” mused Harley.  “That’s possible.  But such was not my impression.”

He turned again to Phil Abingdon.  “This Ormuz Khan, I understood you to say, actually resides in or near London?”

“He is at present living at the Savoy, I believe.  He also has a house somewhere outside London.”

There were a hundred other questions Paul Harley was anxious to ask:  some that were professional but more that were personal.  He found himself resenting the intrusion of this wealthy Oriental into the life of the girl who sat there before him.  And because he could read a kindred resentment in the gloomy eye of Doctor McMurdoch, he was drawn spiritually closer to that dour character.

By virtue of his training he was a keen psychologist, and he perceived clearly enough that Phil Abingdon was one of those women in whom a certain latent perversity is fanned to life by opposition.  Whether she was really attracted by Ormuz Khan or whether she suffered his attentions merely because she knew them to be distasteful to others, he could not yet decide.

Anger threatened him—­as it had threatened him when he had realized that Nicol Brinn meant to remain silent.  He combated it, for it had no place in the judicial mind of the investigator.  But he recognized its presence with dismay.  Where Phil Abingdon was concerned he could not trust himself.  In her glance, too, and in the manner of her answers to questions concerning the Oriental, there was a provoking femininity—­a deliberate and baffling intrusion of the eternal Eve.

He stared questioningly across at Doctor McMurdoch and perceived a sudden look of anxiety in the physician’s face.  Quick as the thought which the look inspired, he turned to Phil Abingdon.

She was sitting quite motionless in the big armchair, and her face had grown very pale.  Even as he sprang forward he saw her head droop.

“She has fainted,” said Doctor McMurdoch.  “I’m not surprised.”

“Nor I,” replied Harley.  “She should not have come.”

He opened the door communicating with his private apartments and ran out.  But, quick as he was, Phil Abingdon had recovered before he returned with the water for which he had gone.  Her reassuring smile was somewhat wan.  “How perfectly silly of me!” she said.  “I shall begin to despise myself.”

Presently he went down to the street with his visitors.

“There must be so much more you want to know, Mr. Harley,” said Phil Abingdon.  “Will you come and see me?”

He promised to do so.  His sentiments were so strangely complex that he experienced a desire for solitude in order that he might strive to understand them.  As he stood at the door watching the car move toward the Strand he knew that to-day he could not count upon his intuitive powers to warn him of sudden danger.  But he keenly examined the faces of passers-by and stared at the occupants of those cabs and cars which were proceeding in the same direction as the late Sir Charles Abingdon’s limousine.
