He laid his hand on hers where it still rested on his sleeves:

"But that's my business, Miss Norne," he added with a smile. "So, otherwise, it being merely a plain business affair between you and me, I think I may also venture my immortal soul alone with you in my room."

The girl flushed darkly.

"You have misunderstood," she said.

He looked at her coolly, intently; and arrived at no conclusion. Young, very lovely, confessedly without moral principle, he still could not believe her actually depraved. "What did you mean?" he said bluntly.

"In companionship with the lost, one might lose one's way--unawares....

Do you know that there is an Evil loose in the world which is bent upon conquest by _obtaining control of men's minds_?"

"No," he replied, amused.

"And that, through the capture of men's minds and souls the destruction of civilisation is being planned?"

"Is that what you learned in your captivity, Miss Norne?"

"You do not believe me."

"I believe your terrible experiences in China have shaken you to your tragic little soul. Horror and grief and loneliness have left scars on tender, impressionable youth. They would have slain maturity--broken it, crushed it. But youth is flexible, pliable, and bends--gives way under pressure. Scars become slowly effaced. It shall be so with you. You will learn to understand that nothing really can harm the soul."

For a few moments' silence they stood facing each other on the dim landing outside his locked door.

"Nothing can slay our souls," he repeated in a grave voice. "I do not believe you really ever have done anything to wound even your self-respect. I do not believe you are capable of it, or ever have been, or ever will be. But somebody has deeply wounded you, spiritually, and has wounded your mind to persuade you that your soul is no longer in God's keeping. For that is a lie!"

He saw her features working with poignant emotions as though struggling to believe him.

"Souls are never lost," he said. "Ungoverned passions of every sort merely cripple them for a space. God always heals them in the end."

He laid his hand on the door-knob once more and lifted the latch-key.

"Don't!" she whispered, catching his hand again, "if there should be somebody in there waiting for us!"

"There is not a soul in my rooms. My servant sleeps out."

"There _is_ somebody there!" she said, trembling.

"Nobody, Miss Norne. Will you come in with me?"

"I don't dare----"

"Why?"

"You and I alone together--no! oh, please--please! I am afraid!"

"Of what?"

"Of--giving you--my c-confidence--and trust--and--and f-friendship."

"I want you to."

"I must not! It would destroy us both, soul and body!"

"I tell you," he said, impatiently, "that there is no destruction of the soul--and it's a clean comradeship anyway--a fighting friendship I ask of you--_all_ I ask; all I offer! Wherein, then, lies this peril in being alone together?"

"Because I am finding it in my heart to believe in you, trust you, hold fast to your strength and protection. And if I give way--yield--and if I make you a promise--and _if there is anybody in that room to see us and hear us--then_ we shall be destroyed, both of us, soul and body----"

He took her hands, held them until their trembling ceased.

"I'll answer for our bodies. Let God look after the rest. Will you trust Him?"

She nodded.

"And me?"

"Yes."

But her face blanched as he turned the latch-key, switched on the electric light, and preceded her into the room beyond.

The place was one of those accentless, typical bachelor apartments made comfortable for anything masculine, but quite unlivable otherwise.

Live coals still glowed in the hob grate; he placed a lump of cannel coal on the embers, used a bellows vigorously and the flame caught with a greasy crackle.

The girl stood motionless until he pulled up an easy chair for her, then he found another for himself. She let slip her furs, folded her hands around the bunch of violets and waited.

"Now," he said, "I'll come to the point. In 1916 I was at Plattsburg, expecting a commission. The Department of Justice sent for me. I went to Washington where I was made to understand that I had been selected to serve my country in what is vaguely known as the Secret Service--and which includes government agents attached to several departments.

"The great war is over; but I am still retained in the service. Because something more sinister than a hun victory over civilisation threatens this Republic. And threatens the civilised world."

"Anarchy," she said.

"Bolshevism."

She did not stir in her chair.

She had become very white. She said nothing. He looked at her with his quiet, reassuring smile.

"That's what I want of you," he repeated.

"I want your help," he went on, "I want your valuable knowledge of the Orient. I want whatever secret information you possess. I want your rather amazing gifts, your unprecedented experience among almost unknown people, your familiarity with occult things, your astounding powers--whatever they are--hypnotic, psychic, material.

"Because, to-day, civilisation is engaged in a secret battle for existence against gathering powers of violence, the force and limit of which are still unguessed.

"It is a battle between righteousness and evil, between sanity and insanity, light and darkness, God and Satan! And if civilisation does not win, then the world perishes."

She raised her still eyes to his, but made no other movement.

"Miss Norne," he said, "we in the International Service know enough about you to desire to know more.
