Jack, now thoroughly recovered, called almost daily at Ba.s.sett Road, and would often bring Muriel to the Cecil to tea or to luncheon. Often I inquired the whereabouts of her father and of Hylton Chater, but she declared herself in entire ignorance, and believed they were abroad.

One afternoon, shortly before Christmas, as we were idling in the American bar of the hotel, my friend told me that Muriel had invited us to tea at her cousin's that afternoon, and accordingly we went there in company.

The drawing-room into which we were ushered was familiar to me as the apartment wherein I had told Muriel of the attempt upon her lover's life.

As we sat together Muriel, a smart figure in a pale blue gown, poured tea for us and chatted more merrily, I thought, than ever before. She seemed quick and nervous and yet full of happiness, as she should indeed have been, for Jack Durnford was one of the best fellows in the world, and his restoration to health little short of miraculous.

"Gordon," he said to me with a sudden seriousness when tea had ended and we had placed down our cups. "I want to tell you something--something I've been longing always to tell you, and now I have got dear Muriel's consent. I want to tell you about her father and his friends."

"And about Elma, too?" I said in quick eagerness. "Yes, tell me everything."

"No, not everything, for I don't know it myself. But what I know I will explain as briefly as I can, and leave you to form your own conclusions.

It is," he went on, "a strange--most amazing story. When I myself became first cognizant of the mystery I was on board the flagship the _Renown_, under Admiral Sir John Fisher. We were lying in Malta when there arrived the English yacht _Iris_, owned by Mr. Philip Leithcourt, and among those on board cruising for pleasure were Mr. Martin Woodroffe, Mr.

Hylton Chater, and the owner's wife and daughter Muriel.

"Muriel and I met first at a tennis-party, and afterwards frequently at various houses in Malta, for anyone who goes there and entertains is soon entertained in return. A mutual attachment sprang up between Muriel and myself," he said, placing his hand tenderly upon hers and smiling, "and we often met in secret and took long walks, until quite suddenly Leithcourt said that it was necessary to sail for Smyrna to pick up some friends who had been traveling in Palestine. The night they sailed a great consternation was caused on the island by the news that the safe in the Admiral Superintendent's office had been opened by expert safe-breakers, and certain most important secret doc.u.ments stolen."

"Well?" I asked, much interested.

"Again, two months later, when the villa of the Prince of Montevachi, at Palmero, was broken into and the whole of the famous jewels of the Princess stolen, it was a very strange fact that the _Iris_ was at the moment in that port. But it was not until the third occasion, when the yacht was at Villefranche, and our squadron being at Toulon I got four days' leave to go along the Riviera, that my suspicions were aroused, for at the very hour when I was dining at the London House at Nice with Muriel and a schoolfellow of hers, Elma Heath--who was spending the winter there with a lady who was Baron Oberg's cousin--that a great robbery was committed in one of the big hotels up at Cimiez, the wife of an American millionaire losing jewels valued at thirty thousand pounds.

Then the robberies, coincident with the visit of the yacht, aroused my strong suspicion. I remarked the nature of those doc.u.ments stolen from Malta, and recognized that they could only be of service to a foreign government. Then came the Leghorn incident of which you told me. The yacht's name had been changed to the _Lola_, and she had been repainted.

I made searching inquiry, and found that on the evening she was purposely run aground in order to strike up a friendship at the Consulate, a Russian gunboat was lying in the vicinity. The Consul's safe was rifled, and the scheme certainly was to transfer anything obtained from it to the Russian gunboat."

"But what was in the safe?" I asked.

"Fortunately nothing. But you see they knew that our squadron was due in Leghorn, and that some extremely important despatches were on the way to the Admiral--secret orders based upon the decision of the British Cabinet as to the vexed question of Russian ships pa.s.sing the Dardanelles--they expected that they would be lodged in the safe until the arrival of the squadron, as they always are. They were, however, bitterly disappointed because the despatches had not arrived."

"And then?"

"Well, the only Russian who appeared to have any connection with them was Baron Oberg, the Governor-General of Finland, whose habit it was to spend part of the winter in the Mediterranean. From Elma Heath's conversation at dinner that evening at Nice I gathered that she and her uncle had been guests on the _Iris_ on several occasions, although I must say that Muriel was extremely reticent regarding all that concerned the yacht."

"Of course," she said quickly. "Now that I have told you the truth, Jack, don't you think it was only natural?"

"Most certainly, dear," he answered, still holding her hand. "Yours was not a secret that you could very well tell to me until you could thoroughly trust me, especially as your father had been implicated in the theft of those doc.u.ments from Malta. The truth is," he said, turning to me, "Philip Leithcourt has all along been the catspaw of Baron Oberg.

A few years ago he was a well-known money-lender in the city, and in that capacity met the Baron, who, being in disgrace, required a loan. He was also in the habit of having certain shady transactions with that daring gang of continental thieves of whom d.i.c.k Archer and Hylton Chater were leaders. For this reason he purchased a yacht for their use, so that they might not only use it for the purpose of storing the stolen goods, but for the purpose of sailing from place to place under the guise of wealthy Englishmen traveling for pleasure. Upon that vessel, indeed, was stored thousands and thousands of pounds' worth of jewels and objects of value, the proceeds of many great robberies in England, France and Belgium. Sometimes they traveled for the purpose of disposing of the jewels in various inland towns where the gems, having been recut, were not recognized, while at other times, Chater and Archer, a.s.sisted by Mackintosh, the captain, and Olinto Santini, the steward, sailed for a port, landed, committed a robbery, and then sailed away again, quite unsuspected, as rich Englishmen."

"And the crew?" I asked, after a pause.

"They were, of course, well paid, and were kept in ignorance of what the supposed owner and his friends did ash.o.r.e."

"But Oberg's connection with it?" I asked, surprised at those revelations.

"Ah!" exclaimed Muriel. "The ingenuity of that crafty villain is fiendish. Before he got into the Czar's favor he owed my father a large sum, and then sought how to evade repayment. By means of his spies he discovered the real purpose of the cruises of the _Iris_--for I was often taken on board with a maid in order to allay any suspicion that might arise if only men were cruising. Then he not only compelled my father to cancel the debt, but he impressed the vessel and those who owned and navigated it into the secret service of Russia. A dozen times did we make attempts to obtain secret papers from Italian, French and English dockyards, but only once in the case of Malta and once at Toulon did we succeed. Ah! Mr. Gregg," she added, "you do not know all the anxiety I suffered, how at every hour we were in danger of betrayal or capture, and of the hundred narrow escapes we have had of Custom House officers rummaging the yacht for contraband. You will no doubt recollect the sensation caused by the theft of the jewels of the Princess Wilhelmine of Schaumbourg-Lippe from the lady's-maid in the rapide between Cannes and Les Arcs, the robbery from the Ma.r.s.eilles branch of the Credit Lyonnais, and the great haul of plate from the chateau of Bardon, the Paris millionaire, close to Arcachon."

"Yes," I said, for they were all robberies of which I had read in the newspapers a couple of years before.

"Well," she said, "they were all committed by Archer or Woodroffe and his gang--with accomplices ash.o.r.e, of course--and never once did it seem that any suspicion fell upon us. While the police were frantically searching hither and thither, we used to weigh anchor and calmly steam away with our booty on board. We had with us an old Dutch lapidary, and one of the cabins was fitted as a workshop, where he altered the appearance of the stones, and prepared them ready for sale, while the gold was melted in a crucible and put ash.o.r.e to be sent to agents in Hamburg."

"But that night in Leghorn?" I said. "What happened to poor Elma?"

"I do not know," was Muriel's reply. "We were both on board together, and standing at the crack of the door watched you sitting at dinner that evening. Elma told me that she believed that there was a plot against your life, but why she would not tell me. She evidently knew of the proposed rifling of the safe at the Consulate. Oberg himself was also on board, locked in his own cabin. Elma must have overheard some conversation between the Baron and one of the others, for she was in great fear the whole time lest they might injure you. Yet it seemed, after all, as though their idea was the same as always, to worm themselves into your confidence. The instant, however, you went ash.o.r.e, Chater, Woodroffe--whom you called Hornby--and Mackintosh, the captain--who, by the way, was an old ticket-of-leave man--went ash.o.r.e, and, of course, broke into the Consulate. Then, as soon as they returned, Elma came to my cabin, awoke me, and said that the Baron was taking her ash.o.r.e, and that they were to travel overland back to London.

She was ready dressed to go, therefore I kissed her, and promising to meet her soon, we parted. That was the last I saw of her. What happened to her afterwards only she alone can tell us."

"But she is not the Baron's niece?" I said.

"No. There is some mystery," declared Muriel. "She holds some secret which he fears she may divulge. But of what nature, I am in ignorance."

"Then you say that your father has never taken any active part in the robberies?" I remarked.

"No. He commenced by lending money, and ama.s.sed a considerable fortune.

Then avarice seized him, as it does so many men, and coming into contact with Archer and his friends, he saw that the idea of the yacht was a safe and profitable one. Therefore he purchased the vessel, and ran it at the disposition of the thieves, and subsequently under compulsion in the secret service of Russia, as I have already described to you. The profits were colossal. In one year my father's share was eighty thousand pounds."

"And where is your father now?" I asked.

"Ah!" she exclaimed sadly, her face pale and haggard.

"I have heard that the vessel was scuttled somewhere in the Baltic."

"That is true. Oberg's purpose having been served, he demanded half the property on board, or he would give notice to the Russian naval authorities that the pirate yacht was afloat. He attempted to blackmail my father, as he had already done so many times, but his scheme was frustrated. My father, because of his inhuman treatment of poor Elma, defied him, when it appears that Oberg, who was in Helsingfors, telegraphed to the admiral of the Russian fleet in the Baltic. The crew from the _Iris_ were at once landed at Riga, and only Mackintosh and my father put to sea again. Ah! my father was desperate, for he knew the merciless character of that man whose victim he had been for so long.

They watched a Russian cruiser bearing down upon them, when, just as it drew near, they got off in a boat and blew up the yacht, which sank in three minutes with its ill-obtained wealth on board."

"And your father?"

She was silent, and I saw tears standing in her eyes.

"There was a tragedy," Jack explained in a low, hoa.r.s.e voice. "He and the captain did not, unfortunately, get sufficiently far from the yacht when they blew her up, and they went down with her."

And I looked in silence at Muriel, who stood with her head bent and her white face covered with her hands.

Almost at the same moment there was a low tap at the door, and the servant-maid announced:

"Mr. Santini, miss."

"Ah!" exclaimed Jack quickly, as Olinto entered the room. "Then you had my note! We have asked you here to reveal to us this dastardly plot which seemed to have been formed against Mr. Gregg and myself. As you know, I've had a narrow escape."

"I know, signore. And the Signor Commendatore is also threatened."

"By whom?"

"By those who killed my poor wife, and who intended also to silence me,"

was his answer.

"The same who compelled you take me to that house where the fatal chair was prepared, eh?"

"It was Archer, who, fearing that you came to London in search of them, devised that devilish contrivance," he said in his broken English. Then continuing, he went on fiercely: "Now that I have discovered why my poor Armida was killed, I will tell the truth, and not spare them. Since you left Scotland, signore, I have been up in Dumfries, and have discovered several facts which prove that for some reason known only to himself, Leithcourt, while at Rannoch, wrote to both Armida and myself separately, making an appointment to see us at the same time at that spot on the edge of the wood, as he had some secret commission to entrust to us. The letter addressed to me apparently fell into someone else's hands--probably one of the secret agents of Baron Oberg, who were always watching Leithcourt's doings, and he, anxious to learn what was intended, made himself up to look like me, and kept the appointment in my place. Armida, having received the letter unknown to me, went up to Scotland, and was also there at the appointed time. What actually transpired can only be surmised, yet it seems that Leithcourt was in the habit of going up to that spot and loitering there in the evening in order to meet Chater in secret, as the latter was in hiding in a small hotel in Dumfries. Therefore those who formed the plot must have endeavored to throw suspicion upon Leithcourt. It is plain, however, as both myself and Armida knew the gang, it was to their interest to get rid of us, because the suspicions of the police had at last become aroused. Poor Armida was therefore deliberately enticed there to her death, while the inquisitive man whom the a.s.sa.s.sin took to be myself was also struck down."

"By whom?"

"Not by Chater, for he was in London on that night."
