"_Within the past hour I have ascertained that your friend Yolande de Foville is a secret agent. Keep strict watch upon her. I have left instructions that if she leaves Paris she is to be followed. I go to Berlin at once to make inquiries, and am leaving by the 4:30 train this morning. I have the address you gave, and the particulars concerning her. Shall return as soon as possible_.

"K."

I crushed the note in my hand, and, walking on into my sitting-room, gulped down some brandy. Everything had conspired against me. When I had given Kaye those details concerning my charming little friend three years ago, I had never dreamed that he would register them and afterwards use them in an endeavour to fasten upon her a charge of being a spy. Yet he was actually on his way to Berlin, and any attempt upon my part to hinder him would only be misconstrued into a treasonable endeavour to shield her.

Upon the table before me stood her photograph in a silver frame, looking out at me. I took it up. Those eyes were so innocent that I could not bring myself to believe that any evil lurked in them. Surely she would not attempt to harm me? Such an action was absolutely contrary to any woman's nature.

Yolande! The sound of that name brought back to me a sweet, tender memory of the past. I sighed as the recollection of that bygone day arose within me, and flung myself down into an easy-chair to smoke and to think. In the blue ascending rings from my cigarette her face seemed to smile at me with those red parted lips and merry eyes, clear and azure as a child's. How charming and chic she had once appeared to me in those days when we had first met--in those days before I had known Edith Austin, my absent well-beloved! Her portrait, too, was there--the picture of a woman, sweet, tender, grave-faced, of similar age perhaps, but whose peerless beauty was typically English and devoid of any artificiality. I took it up and touched it reverently with my lips. I loved the original of that photograph with all the strength of my being, hoping always that some day ere long I might ask her to become my wife.

Some there are who hold the theory that to all diplomatists, amba.s.sadors excepted, wives are an unnecessary enc.u.mbrance. I admit that there is much to be said in favour of the celibate state as the ideal existence for the secretary or attache, who is bound, more or less, to make himself agreeable to the many cosmopolitan ladies who make up the diplomatic circle, and sometimes even to flirt with them, when occasion requires. Yet after fifteen years or so beneath the shadows of the various thrones of Europe, a man tires of the life, and longs for the one sweet woman whom he can trust and love. In this I was no exception.

I loved Edith Austin with all my heart and all my soul; and she, I felt a.s.sured, reciprocated my affection.

It is part of the diplomatist's creed to be on good terms with all and sundry of the feminine b.u.t.terflies who hover about the emba.s.sies, no matter what their age or nationality. Hence it was that five years ago, while stationed at Brussels, I had become attracted by Yolande de Foville. Once, long before I met Edith, I fancied myself in love with her. Her father, Count de Foville, was aide-de-camp to King Leopold, and with her mother she moved in the best society in Paris and Brussels.

On several occasions I had been invited for the boar hunting at the great gloomy old chateau at Houffalize, in the Ardennes forest, where the powerful de Fovilles had been seigneurs through five centuries.

It was a dull, s...o...b..und, dreary place in winter, bare and chill, furnished in ancient style, and situated thirty miles from the nearest railway, in the midst of a flat forest country. It was, therefore, not surprising that on the death of the Count, Yolande and her mother should prefer to leave Belgium and travel in England and Italy, spending the winter at Rome or at Monte Carlo, the spring in Paris, and summer in one or other of the fashionable French watering-places. During three years we had been excellent friends, and after I had been promoted from Brussels to the Emba.s.sy in Rome, she came with her mother and spent the spring in the Eternal City, with the result that our firm friendship became even firmer. I am fain to admit that our flirtation was of the kind called desperate, and that it had ended in love.

And a week ago she had suddenly arrived in Paris at the smart little flat in the Rue de Courcelles, which her mother had possessed for years, but now so seldom occupied. Her arrival was unexpected, and I had only known of it from Giraud, the military attache at the Belgian Legation, a friend of my Brussels days, whom I met in the Cafe de Paris one evening after the opera, and who had said suddenly:

"Do you, my dear Ingram, know that a little friend of yours has arrived in Paris?"

"Who?" I inquired eagerly.

"Yolande," was the response. "You used to be her cavalier in Brussels in the old days. Have you forgotten her?"

His announcement surprised me. Since my friendship with Edith had grown to be a grand pa.s.sion, I had exchanged no correspondence with Yolande.

Indeed, the last I had heard of her was that she and the Countess were at Cairo spending the winter.

To tell the truth I was rather glad that she had not sought me out, for I had no wish to renew her acquaintance, now that I had found a woman in England whom I meant to try to win for my wife. Yet as I looked back at the past through the haze of my cigarette-smoke I was compelled to admit that I had spent some charming hours by her side, dancing at those brilliant b.a.l.l.s in Brussels or driving in that pretty wood so beloved of the Bruxellois, the Bois de la Cambre. Many were the incidents that came back to me as I sat there pondering. Nevertheless, in the storehouse of memory I found nothing half sweet enough to tempt me from my love for Edith.

The denunciation of the pretty Yolande as a spy staggered belief; yet the Chief himself, as well as Kaye, was convinced, and the latter was already on his way to the north to prosecute inquiries.

What, I wondered, had really aroused their suspicions? As His Excellency had not seen Kaye since his return from Madrid, they could not have exchanged views. It seemed my duty to call and see her, to renew the acquaintance that I so strongly desired to end, and, indeed, to continue the flirtation of bygone days with a view to discovering the truth. Was it fair? Was it just? I hesitated to call upon her, half fearful lest her charm and natural chic should again attract me towards her. Nevertheless, it was my duty, as servant of my Sovereign, to attempt to discover England's secret enemies.

CHAPTER THREE.

YOLANDE.

The remainder of that night I spent in restless agitation, and at the Emba.s.sy early next morning showed His Excellency the note that Kaye had left for me.

"You must see her, Ingram," he said briefly. "You must obtain her secret from her."

"But I cannot believe that she is a secret agent!" I declared. "We were friends, and she surely would not seek to injure me?"

"Trust n.o.body, my dear Ingram," answered the grave-eyed old man. "You know how unreliable women are where diplomacy is concerned. Remember the incident of the Princess Ghelarducci in Rome."

My lips compressed themselves. He referred to a matter which, for me, was anything but a pleasant recollection. The Princess, after learning our intentions regarding Abyssinia, had openly betrayed us; and I had very foolishly thought her my friend.

"I shall call on her this afternoon," I answered briefly. "The worst of it is that my action will lead her to think that I desire to renew the acquaintance."

"H'm, I see," observed His Excellency quickly, for his shrewdness had detected the truth. "You were once in love with her--eh?"

I nodded.

"Then don't allow her to think that your love has cooled," he urged.

"Act diplomatically in this matter, and strive to get at the truth."

"And deceive her?"

"Deception is permissible if she is a spy."

"But she is not a spy," I declared quickly.

"That remains to be seen!" he snapped. He then turned on his heel and pa.s.sed into an adjoining room.

At three o'clock I presented my card at the flat in the Rue de Courcelles, and was admitted to a cosy little salon, where the persiennes were closed to keep out the blazing July sun, and the subdued light was welcome after the glare of the streets. Scarcely, however, had my eyes become accustomed to the semi-darkness, when the door suddenly opened, and I found myself face to face with the woman I had loved a few years ago.

"Gerald! You!" she cried in English, with that pretty accent which had always struck me as so charming.

Our hands clasped. I looked into her face and saw that in the two years which had elapsed she had grown even more beautiful. In a cool white dress of soft, clinging muslin, which, although simply made, bore the unmistakable stamp of a couturiere of the first order, she stood before me, my hand in hers, in silence.

"So you have come to me?" she said in a strained voice. "You have come, at last?"

"You did not let me know you were in Paris," I protested.

"Giraud told you four days ago," she responded, "and you could not spare a single half-hour for me until to-day!" she added in a tone of reproach. "Besides, I wrote to you from Cairo, and you never replied."

"Forgive me," I urged--"forgive me, Yolande. It is really my fault."

"Because you have forgotten me," she said huskily. "Here, in Paris, you have so many distractions that memories of our old days in Brussels and at Houffalize have all been swept away. Come, admit that what I say is the truth."

"I shall admit nothing of the kind, Yolande," I answered, with diplomatic caution. "I only admit my surprise at finding you here in July. Why, there is n.o.body here except our unfortunate selves at the emba.s.sies. The boulevards are given over to the perspiring British tourist in knickerbockers and the usual week-end trippers who `do' the city in a char-a-banc."

She laughed for the first time, and seated herself upon a large settee covered with yellow silk, motioning me to a chair near her.

"It is true," she said. "Paris is not at all pleasant just now. We are only here for frocks. In a week we go to Marienbad. And you--how are you?" and she surveyed me with her head held slightly aside in that piquante manner I knew so well.

"The same," I laughed--"ever the same."

"Not the same to me," she hastened to protest.

"I might make a similar charge against yourself," I said. "Remember, you did not tell me you were in Paris."

"Because I thought you would know it quickly enough. I wanted, if possible, to meet you accidentally and surprise you. I went to the ball at the German Emba.s.sy, but you were not there."

"I was in London," I explained briefly, my thoughts reverting to the allegation against her and the unhesitating action of the wary Kaye in travelling direct to Berlin.
