If there was any man in Europe who could clear up a mystery it was the indefatigable chief of the British secret service. He lived in Paris ostensibly as an English lawyer, with offices in the Boulevard des Italiens, next the Cafe Americain. Hence his sudden journeys. .h.i.ther and thither were believed to be undertaken in the interests of various clients. But although he had an Irish solicitor, O'Brien by name, to attend to the inquiries of any chance clients, the amount of legal business carried on in those offices was really nil. The place was, in fact, the headquarters of the British secret service on the Continent.

"I, too, was in England a year ago," she said. "We were invited to a house-party up in Scotland. Mother was bored, but I had great fun. An English home seems somehow so much jollier than the houses where one visits in any other country. You know how I love the English!"

"Is that meant as a compliment?" I laughed.

"Of course," she answered. "But English diplomatists are just as grave as those of any other nation. Your people are always full of all sorts of horrid secrets and things."

She referred to the old days in Brussels, for she knew well the difficulties under which our diplomacy had been conducted there, owing to the eternal questions involving Egypt and the Congo.

But I laughed lightly. I did not intend that she should suspect the real motive of my call. Evidently she knew nothing of my love for Edith Austin, or she would have referred to it. Fortunately I had been able to keep it a secret from all.

"And you are actually leaving us in a week?"

I observed, for want of something else to say. "I hear that Marienbad is crowded this season."

"We are going to visit my uncle, Prince s...o...b..rg, who has a villa there."

Then I asked her of our mutual friends in Brussels, and she in return retailed to me all the latest gossip concerning them. As she sat there in the subdued light, her white dress, relieved by a touch of turquoise at the wrists and waist, she presented a picture graceful, delicate, and altogether charming. I reasoned with myself as she went on chattering.

No; it was not surprising that I had once fallen in love with her. She was more French than Belgian, for the days of her girlhood had been pa.s.sed mostly in France; her Christian name was French, and in manner she possessed all that smartness and chic peculiar to the Parisienne.

Mentally I compared her with Edith, but next instant laughed within myself. Such comparison was impossible. Their styles were as different as were their nationalities. Beside Edith, my well-beloved, the beauty of this fair-haired, gesticulating girl paled entirely, and became insipid. The Englishwoman who held me beneath the spell of her soft and truthful eyes was without a peer.

Still, Yolande amused me with her chatter. The reader will forgive me this admission, for in calling there I was only acting a part. I was endeavouring in the interests of my country to find out whether there was any truth in the allegation recently made against her by my friend.

Of a sudden a thought crossed my mind, and I asked:

"Have you met many acquaintances since you've been in Paris?"

"Only Hartmann and some of the people at the Legation," she responded.

"We are just going to five o'clock with the Princess Olsoufieff this afternoon."

"There is an old friend of yours just arrived," I said. "Have you met him?"

"An old friend?" she echoed in surprise. "Man or woman?"

"A man," I answered. "Rodolphe Wolf."

"Rodolphe Wolf!" she gasped, starting up, the colour dying from her lips in an instant. "Rodolphe Wolf in Paris--impossible!"

"He was at the Baroness de Chalencon's last night," I said quite calmly, watching her face the while.

Her sudden fear and surprise made plain a fact of which I had not before been aware--namely, that there was something more than a casual link between them. Years ago, when in Brussels, I had suspected Wolf of being a secret agent, and the fact that she was closely acquainted with him appeared to prove that my Chiefs suspicion was not unfounded.

She had risen. Her hands were trembling, and although she strove desperately to betray to me no outward sign of agitation, she was compelled to support herself by clutching the small table at her side.

Her countenance was blanched to the lips. She presented the appearance of one haunted by some terrible dread.

"Wolf!" she gasped again, as though speaking to herself. Then, turning to me, she stretched forth both her hands, and, looking earnestly into my eyes, cried in wild desperation: "Gerald, save me! For the sake of our love of the old days, save me!"

"From what?" I cried, jumping up and catching her by both hands. "Tell me, Yolande. If I can a.s.sist you I certainly will. Why are you so distressed?"

She was silent, with one trembling hand pressed upon her heart, as though to stay its wild, tumultuous beating.

"No," she said in a hoa.r.s.e whisper, "it is useless--all useless."

"But if you are in distress I can surely help you," I said.

"Alas! you cannot," she answered in despair. "You do not know--you cannot understand."

"Why not tell me? Confide in me," I urged.

"No," she replied. "I am very foolish--forgive me;" and she tried to smile.

"The news that Wolf is here has upset you," I said. "Why?"

"He has escaped."

"From where?"

"From prison."

I was silent. I knew not what to say. This declaration of hers was strange. It was startling news to me that Rodolphe Wolf had been in prison.

"You have asked me to save you," I said, reverting to her wild supplication. "I will do so willingly if you only tell me how."

"It is impossible," she said in a broken voice, shaking her head mournfully. "By what you have told me I am forewarned."

A deep sigh escaped her, and I saw that her fingers worked restlessly in the palms of her hands. She was desperate.

"Can I do absolutely nothing?" I asked in a tone of sympathy, placing my hand tenderly upon her shoulder.

"Nothing," she answered in a hoa.r.s.e whisper. "I am not fit to talk further. Let us say good-bye."

"Then you prefer that I should leave you?"

"Yes," she said, holding out her hand. "Forgive me for this, but I want to go to my own room to think. What you have told me has upset me."

"Tell me plainly--you fear that man?"

She nodded in the affirmative.

"And you will not allow me either to advise or to a.s.sist you?"

"No," she said hoa.r.s.ely. "Go, Gerald. Leave me! When we meet again I shall be calmer than I am now."

Her face was deathly pale; her eyes had a distinct look of terror in them.

"Very well," I answered when again she had urged me to leave her; "if you insist, I will go. But remember that if I can be of service, Yolande, I am ready at once to render you a.s.sistance. Good-bye," and I pressed her hand in sympathy.

She burst into tears.
