"And what may your business be with me?" asked the master of Wroxeter.

The man glanced suspiciously at the door by which Dudley had entered, and asked:

"Are we alone? Do you think there can possibly be any eavesdroppers?"

"Certainly not. But I cannot understand why your business should be of such a purely private character. You are entirely unknown to me, and I understand that you refused to give a card." He uttered the last words with a slight touch of sarcasm, for the man's appearance was not such as would warrant the casual observer in believing him to be possessed of that mark of gentility.

"Of course I am unknown to you, Mr. Chisholm. But although unknown to you in person, I am probably known to you by name." As he spoke, he selected from his rather shabby pocket-book a folded paper, which he handed to Dudley. "This credential will, I think, satisfy you."

Dudley took it, glanced at it, and started quickly. Then he fixed his eyes upon his visitor in boundless surprise. The man before him smiled faintly at the impression which the sight of that doc.u.ment had caused.

The paper was headed with the British arms in scarlet, and contained only three lines written over a signature he knew well--the signature of the Prime Minister of England.

"And you are really Captain Cator?" exclaimed the Under-Secretary, looking at him in amazement, and handing him back his credential.

"Yes, Archibald Cator, chief of Her Majesty's Secret Service," said the shrunken-faced man. "We have had correspondence on more than one occasion, but have never met, for the simple reason that I am seldom in England. Now you will at once recognise why I refused a card, and also why I wished my visit to you to remain a secret."

"Of course, of course," answered Dudley. "I had no suspicion of your ident.i.ty, and--well, if you will permit me to say so, your personal appearance at this moment is scarcely that which might be expected of Captain Archibald Cator, military attach in Rome."

"Exactly! But I have been paying a call earlier in the day, and shabbiness was a necessity," he explained with a laugh. "Besides, I tramped all the way from Shrewsbury and--"

"And you are wet and cold. You'll have a stiff whiskey and soda."

Dudley pressed the bell and, when Riggs appeared, gave the necessary order.

"You won't return to-night, of course," suggested Chisholm. "I'll tell them to get a room ready for you."

"Thanks for your hospitality, but my return is absolutely imperative.

There is a train from Shrewsbury to town at 4:25 in the morning. I must leave by that."

Both men sank into chairs opposite each other in the chill, rather gloomy, room. The mysterious visitor who had called at that extraordinary hour was one of the most trusted and faithful servants at the disposal of the Foreign Office. Although nominally holding the appointment of military attach at the Emba.s.sy in Rome, he was in reality the chief of the British Secret Service on the Continent, a man whose career had been replete with extraordinary adventures, to whose marvellous tact, ready ingenuity, and careful methods of investigation, England was indebted for many of the diplomatic _coups_ she had made during the past dozen years or so.

In the diplomatic circle, and in the British colony in Rome, every one knew Archie Cator, for he was popular everywhere, and a welcome visitor at the houses of the English and the wealthier Italians alike. It was often hinted that in the Foreign Office at home he possessed influential friends, for whenever he wished for leave he had only to wire to London to obtain a grant of absence. The supposition was that in summer he went to his pretty villa at Ardenza, on the Tuscan sh.o.r.e near Leghorn, there to enjoy the sea-breezes, or in winter over to Cairo or Algiers.

None knew, save, of course, Her Majesty's Amba.s.sador, that these frequent periods of leave were spent in flying visits to one or other of the capitals of Europe to direct the operations of the band of confidential agents under him, or that the attach so popular with the ladies was in reality the Prince of Spies.

Spying is against an Englishman's notion of fair-play, but to such an extent have the other great Powers carried the operation of their various Intelligence Departments that to the Foreign Office the secret service has become a most necessary adjunct. Were it not for its operations, and the early intelligence it obtains, England would often be left out of the diplomatic game, and British interests would suffer to an extent that would soon become alarming, even to that puerile person, the Little Englander. Officially no person connected with the Secret Service is recognised, except its chief, and he, in order to cloak his real position, was at that moment holding the post of attache in Rome, where he had but little to do, since Italy was the Power most friendly towards England.

Stories without number of the captain's prowess, of his absolute fearlessness, and of his marvellous ingenuity as a spy in the interests of his country, had already reached Chisholm. They were whispered within a certain circle at the Foreign Office when from time to time a copy of a secret doc.u.ment, or a piece of remarkable intelligence reached headquarters from Paris, Berlin, or Petersburg. They knew that it came from Archie Cator, the wiry, middle-aged attach who idled in the _salons_ of the Eternal City, drove in the Corso, and, especially as he was an easy-going bachelor, found remarkable favour in the eyes of the ladies.

He lived two lives. In the one he was a diplomatist, smart, polished, courtly--the perfect model of all a British attach should be. In the other he was a shrewd, crafty spy, possessed of a tact unequalled by any detective officer at Scotland Yard, a brain fertile in invention and subterfuge, and nerves of iron. In Rome, in Paris and in Petersburg, only the amba.s.sadors knew the secret of his real office. He transacted his business direct with them and with the chief in London, Her Majesty's Secretary of State for Foreign Affairs. Indeed, British diplomatic policy was often based upon his reports and suggestions. The utmost care was always exercised to conceal his real office from the staffs of the various Emba.s.sies. They only knew him as Archie Cator from Rome, the man with a friend high up in the Foreign Office who got him short leave whenever he chose to take it.

The money annually voted by Parliament for secret service was entirely at his disposal, and the only account he rendered was to the chief himself. The department was a costly one, for often he was compelled to bribe heavily through his agents, men specially selected for the work of spying; and as these numbered nearly forty, distributed in the various capitals, the expenditure was by no means light. With such a director, for whose methods, indeed, the staff at Scotland Yard had the highest admiration, the successes were many. To Cator's untiring energy, skilful perception, and exhaustless ingenuity in worming out secrets, our diplomatic success in various matters, despite the conspiracies formed against us by certain of the Powers, was entirely due. The Foreign Secretary himself had, it was whispered, once remarked at a Cabinet meeting that if England possessed half a dozen Cators she would need no amba.s.sadors. The marquess trusted him implicitly, relying as much upon his judgment as upon that of the oldest and most practised representative of Her Majesty at any of the European courts.

If the truth were told, the secret of England's dominant influence in Central Africa was entirely due to the discovery of a diplomatic intrigue in Berlin by the omnipotent Cator, who, at risk of his life, secured a certain doc.u.ment which placed our Foreign Office in a position to dictate to the Powers. It was a master-stroke, and as a partial return for it the popular, cigarette-smoking attach in Rome, found one morning upon his table an autograph letter of thanks from Her Majesty's Prime Minister. When occupying his position as attach he was an idler about the Eternal City, an inveterate theatre-goer, and a well-known, and even ostentatious, figure in Roman society. But when at work he was patient, un.o.btrusive, and usually ill-dressed, moving quickly hither and thither, taking long night journeys by the various _rapides_, caring nothing for fatigue, and directing his corps of secret agents as a general does an army.

Knowledge is power. Hence England is compelled to hold her place in the diplomatic intrigues of the world by the employment of secret agents.

There are many doors to be unlocked, and to men like Cator, England does not grudge golden keys.

Riggs had brought the whiskey and soda, and the man whose career would have perhaps made the finest romance ever written, had drained a tumblerful thirstily, with a laugh and a word of excuse that "the way had been long, and the wind cold."

When they were alone again, he twisted the rather stubby ends of his grey moustache, and with his eyes fixed upon the Under-Secretary said:

"I should not have disturbed you at this hour, Mr. Chisholm, were not the matter one of extreme urgency."

Dudley sat eager and anxious, wondering what could have brought this man to England. A grave and horrible suspicion had seized him that the truth he dreaded was actually out--that the blow had fallen. No secret was safe from Cator. As he had obtained knowledge of the profoundest secrets of the various European Powers in a manner absolutely incredible, what chance was there to hide from him any information which he had set his mind to obtain. "Is the matter serious?" he asked vaguely.

"For the present I cannot tell whether it is actually as serious as it appears to be," the other answered with a grave look. "As you are well aware, the outlook abroad at this moment is far from promising. There is more than one deep and dastardly intrigue against us. The diplomatic air on the Continent is full of rumours of antagonistic alliances against England, and even Mercier, in Paris, has actually gone the length of planning an invasion. But a fig for all the b.u.mptious chatter of French invasions!" he said, snapping his finger and thumb. "What we have to regard at this moment is not menaces abroad, but perils at home."

"I hardly follow you," observed the Under-secretary.

"Well, I arrived in London from the Continent the night before last upon a confidential mission, and it is in order to obtain information from yourself that I am here to-night," he explained. "Perhaps the fact that I have not had my clothes off for the past five days, and that I have been in four of the capitals of Europe during the same period, will be sufficient to convince you of the urgency of the matter in hand.

Besides, it may account for my somewhat unrepresentable appearance," he added with a good-humoured laugh. "But now let us get at once to the point, for I have but little time to spare if I'm to catch the early express back to London. The matter is strictly private, and all I ask, Mr. Chisholm, is that what pa.s.ses between us goes no further than these four walls. Recollect that my position is one of constant and extreme peril. I am the confidential agent of the Foreign Office, and you are its Parliamentary Under-secretary. Therefore, in our mutual interests, no word must escape you either in regard to my visit here, or even to the fact that I have been in England. London to-day swarms with foreign spies, and if I am recognised all my chances of being successful in the present matter must at once vanish."

"I am all attention," said Dudley, interested to hear something from this gatherer of the secrets of the nation. "If I can give you any a.s.sistance I shall be most ready to do so."

"Then let me put a question to you, which please answer truthfully, for much depends upon it," he said slowly, his eyes fixed upon the man before him as he pensively twisted his moustache. "Were you ever acquainted with a man named Lennox?"

The words fell upon Dudley Chisholm like a thunderclap. Yes, the blow had fallen! He started, then, gripping the arms of the chair, sat upright and motionless as a statue, his face blanched to the lips. He knew that the ghastly truth, so long concealed that he had believed the matter forgotten, was out. Ruin stood before him. His secret was known.

CHAPTER NINETEEN.

A MAN OF SECRETS SPEAKS.

Archibald Cator's bony face was grave, serious, sphinx-like. His personality was strange and striking.

He had detected in an instant the sudden alarm which his question had aroused within the mind of the man before him, but, pretending not to observe it, he added with a pleasant air:

"You will, of course, forgive anything which may appear to be an impertinent cross-examination, Mr. Chisholm. Both of us are alike working in the interests of our country, and certain facts which I have recently unearthed are, to say the least, extremely curious. They even const.i.tute a great danger. Do you happen to remember any one among your acquaintances named Lennox--Major Mayne Lennox?"

Mayne Lennox! Mention of that name brought before Chisholm's eyes a grim and ghastly vision of the past--a past which he had fondly believed was long ago dead and buried. There arose the face that had haunted him so continuously, that white countenance which appeared to him in his dreams and haunted him even in the moments of his greatest triumphs, social and political.

The shabbily attired man patiently awaited an answer, his eyes fixed upon the man before him.

"Yes," answered Dudley at last, with a strenuous effort to calm the tumultuous beating of his heart.

"I was once acquainted with a man of that name."

His visitor slowly changed his position, and a strange half-smile played about the corners of his mouth, as though that admission was the sum of his desire.

"May I ask under what circ.u.mstances you met this person?" he inquired, adding: "I am not asking through any idle motive of curiosity, but in order to complete a series of inquiries I have in hand, it is necessary for certain points to be absolutely clear."

"We met at a card-party in a friend's rooms," Dudley said. "I saw something of him at Hastings, where he was spending the summer.

Afterwards, I believe, he went abroad. But we have not met for years."

"For how many years?"

"Oh, seven, or perhaps eight! I really could not say exactly."

"Are you certain that Mayne Lennox went abroad?" inquired Cator as though suddenly interested.

"Yes. He told me that he had lived on the Continent for a great many years, mostly in Italy, I think. He often spoke of a villa he had outside Perugia, and I presume that he returned there."
