Chapter 13

"Marvellous!" I exclaimed. "I had no idea that medical science could carry inquiries so far. I know that in criminal cases in London our pathologists, with their mirror-tests for arsenic, fix the guilt upon poisoners in a manner most amazing. But I have never heard of this secret and most subtle poison which was placed beside my bed, the intention being for me to tread upon the impregnated pin."

"And if you had done so you would have been taken with a sudden fatal seizure, the cause of which would never have been detected."

"You mean I should have died of poison?"

"You certainly would. No medical aid would have been of any avail, for orosin is the most deadly substance which has ever been discovered. It is indeed good for humanity that it is known to only a few toxicologists, but that in itself reveals the fact, monsieur, that an exceedingly clever and secret attack has been made upon your life. A single puncture of the skin with one or other of those pins which were placed so conveniently at your bedside when you sprang out to meet the intruder, and you would by this time have been buried as one whose death had been due to natural causes!"

I held my breath. This declaration by one of the greatest professors of toxicology in Europe staggered me. A dastardly attempt had been made upon me by one of the most notorious of modern criminals!

Why? No attempt at assassination is made without some motive, and the game must ever be "worth the candle."

The whole of the dramatic incidents of the night flashed across my memory; how I had faced the fellow in my room, challenged him at the point of my pistol, and compelled him to give me meekly proofs of his respectability. Truly it was all humorous--but only from Despujol's point of view.

I recollected those innocent-looking pins which apparently had been left so carelessly in my room. Each held for me a sudden and suspicious death.

"The slightest puncture of the skin would inevitably prove fatal," the Professor continued. "Feeling yourself pricked you would naturally remove the pin and very quickly afterwards death would supervene. So prior to it you yourself would no doubt have removed all trace of the crime!"

"It is as well that such poison is not generally known, or it would be used by many who wished to get rid of their friends," I remarked.

The Professor laughed, and agreed, saying:

"There are several poisons of the same type which are known only to toxicologists, and we are very careful not to allow the public sufficient knowledge of them. I must confess that I never dreamed when I commenced my investigations that I was in the presence of orosin. There is sufficient in this little tube"--and he held it to the light--"to kill a hundred persons. It certainly is one of the most dangerous of known compounds."

"So it is evident that the man Despujol entered my room and placed the pins there intending that I should step upon one or other of them!" I gasped.

"Without doubt. And it seems little short of a marvel that you escaped," said the Professor.

"It certainly does," I remarked. "But I must tell the police of the fact you have established. The affair now assumes a new phase. The man was not in my room with the intention of robbery, but in order to encompass my death by secret means."

"If you had not so fortunately avoided treading upon the pins you certainly would not be alive at the moment," remarked the Professor, again reflectively examining the yellow fluid in the tube. "What motive could the man have had in gaining access to your room and placing the pins there? I suppose he did not risk putting them there before you went to bed, as you might have picked one up on your boot, and that would have drawn your attention to them. By placing them there after you were in bed he hoped that, on getting out, your bare foot would come into contact with one of the impregnated points."

"It was certainly a most fiendish plot!" I declared. "And I thank you, Professor, for taking all this trouble with your analysis and so establishing the truth. I will go to the police and inform them."

"Yes. I wish you to do that, for the fellow is undoubtedly in possession of orosin, and intends to use it. Perhaps he has already killed people by the same subtle and secret means."

"He must be arrested at all costs," I said. "Already the police all over Spain are watching for him, and special surveillance is being kept along all the railways and on the frontier."

"Any person with orosin in his possession should be detained and examined," the Professor declared. "I wonder where he obtained it?"

"Who knows?" I exclaimed, but I was reflecting whether, after all, my presence in Madrid was not known to De Gex. If so, was it possible that he had hired the notorious Despujol to attack me in secret!

"Of course we know that there is a secret traffic in poisons. Medico-legists, with the police, have established that fact over and over again," said Professor Vega. "But the vendors are very difficult to trace. One was found only six months ago--a doctor living in a suburb of Copenhagen. But orosin is not known to a dozen people beyond those who study toxicology. Hence this man Despujol must have been supplied with it by someone who knew."

The suspicion had arisen in my mind that De Gex and his agent Suzor knew that I was in Madrid for the purpose of watching them, and they had resorted to a very clever and secret means of getting rid of me once and for all. If the notorious criminal Despujol was in their pay he would no doubt afterwards blackmail them, now that the desperate plot had failed. Again, could it be possible that Moroni had had any hand in supplying this most effective and dangerous of all secret poisons to the Spanish malefactor who snapped his defiant fingers under the very nose of the police?

As I sat in that quiet room of the Professor's, a room that smelt strongly of chemicals, though it was filled mostly with books, I could not refrain from shuddering when I reflected upon the narrow escape I had had. Yet if De Gex resorted to such measures, he must certainly hold me in great fear. Besides, if my life was threatened, so also was that of my friend Harry Hambledon, who remained so vigilant in the serene belief that his presence was undetected.

At that time I never dreamed that the great financier who controlled the destinies of certain European States never moved without a police official being in attendance, and that surveillance was kept upon him as though he were royalty travelling incognito. De Gex, it seemed, was ever afraid that one of his enemies, the hundreds whom he had ruined by dint of sharp practice, unscrupulous dealing, and flagrant bribery, might seek revenge.

Hence, though neither Hambledon nor myself knew of it, both De Gex and his toady and agent, Gaston Suzor, were well aware of our presence, and, moreover, were kept posted concerning our movements from day to day!

Though we were in ignorance of all this, yet the desperate nature of the plot against me caused me to wonder what exactly was the fear in which De Gex held me. Of course it concerned Gabrielle Tennison. But exactly how, I failed to surmise.

One thing was certain, that the mystery-man of Europe intended to rid himself of me, and in this he was being aided by certain of his friends, chief among whom were Suzor and Moroni. That the assassin Despujol was only a paid servant was quite clear. But the pay must have been a very handsome sum to cause him to dare to come to Madrid so boldly and run the risk of arrest.

I smiled at my own innocence when I remembered how completely he had imposed upon me by showing me his papers of identity, and the photographs of his pretended family. Truly only a great criminal could have remained so imperturbed and polite to the man whom he intended should die.

"This drug orosin is a very mysterious one, I suppose?" I remarked a few seconds later as the Professor, who had offered me a cigar, was in the act of lighting up.

"Yes. A very weak solution taken by the mouth produces extraordinary effects upon the human brain. The latter almost instantly becomes unbalanced and the victim lapses into an unconscious state for days, even for weeks," he said. "Very often the brain is quite normal, save that a complete loss of memory follows the return to consciousness. In other cases orosin has produced complete and hopeless dementia."

"Always hopeless?" I asked eagerly, recollecting my own case and that of Gabrielle Tennison.

"Not always hopeless. There have been cases that have been cured."

"Do you know any personally?" I demanded breathlessly.

"There are one or two--very few--on record. Professor Gourbeil, the well-known alienist of Lyons, has observed two patients who recovered. But the majority of cases where orosin has been administered were found incurable. The mind is blank, the memory completely destroyed, and the general health so undermined that only the strongest persons can withstand the strain."

At once I described Gabrielle's symptoms and general attitude, whereupon the Professor said:

"What you tell me are the exact symptoms exhibited by a person to whom a small dose of orosin has been administered. In most cases, however, such a state of mind develops into actual insanity with a homicidal tendency. Such a patient should be very carefully watched, for in ninety per cent. the chance of a cure is, alas! beyond expectation."

CHAPTER THE EIGHTEENTH

MORE ABOUT THE MYSTERY-MAN

One very important fact I had established. Orosin was the obscure and little-known drug that had been administered to Gabrielle Tennison, as well as to myself, by the mystery-man of Europe at his palatial house in Stretton Street. Gabrielle being the weaker, was still suffering from its paralysing effects, while I, the stronger, had practically recovered.

Yet it had been intended by the daring Despujol that a fatal "accident" should now befall me! And could anything be plainer than that the fellow for whom the police were searching so eagerly was a hireling of the man De Gex who went in fear of me?

That most secret and most potent of all poisons might be known to Moroni! Indeed, it apparently was known to him, and the endeavour had been to introduce it into my system by means of an infected carpet pin.

On leaving Professor Vega I at once sent a note round to Hambledon, and awaited his arrival.

When he came I related all the professor had told me.

"Well, Hugh," he said, "we now know the truth, and it remains for us to combat the fiends. If you are marked down--no doubt I am also. So it behoves us both to be very wary."

"Why can't we tell the police the whole circumstances?" I suggested.

"My dear fellow, they wouldn't believe you, and they wouldn't arrest such a powerful man as Oswald De Gex," was his serious reply. "Money can buy immunity from arrest in every country in Europe, and especially De Gex's money, for it can be distributed in secret by his agents. No. If we are to be successful we must lay our plans just as cleverly as he lays his. We must allow him to believe that we are entirely unsuspicious of his plotting. That is our only way."

I realized that there was much truth in his argument. It remained with us to pretend ignorance. Therefore we resolved to still watch and wait.

A few hours later I told Señor Andrade, the Chief of Police, of the professor's discovery that the points of the pins had been infected with orosin, the newly discovered drug which in small doses produced loss of memory and insanity, and in larger doses sudden death.

In reply, he informed me that though every effort had been made to trace the elusive fugitive, all had been in vain, and that he was still at large.

"But if he has this terrible drug in his possession he is more than ever a danger to society," the Spanish official went on, speaking in French. "I thank you, m'sieur, for all the information you have given me, and you may rely upon me to take every possible step towards securing his arrest. I was in telegraphic communication with the Paris Sûreté only this morning concerning him. I will wire them again. They have been stirred into activity by the message I sent them after your call to see me."

I longed again to be frank with the affable Señor Andrade, yet I saw that if I were I might negative all chance of solving the problem which concerned the health and life of the girl whom I had grown to love so fervently.

Upon a sudden impulse I remarked with affected carelessness:

"I hear that our English financier, Mr. De Gex, is at the Ritz."

"Yes," he replied. "He is here under an assumed name in connexion with some big railway scheme in Estremadura--a line between Toledo and Merida. It is badly wanted, and has been talked of for years. There is a huge stretch of country south of the Tagus as far as Villa Nueva without any railway communication. The King himself has been agitating for the development of that rich agricultural region for the last ten years. And now it seems as though your great financier, Monsieur De Gex, is here to consult with the Ministry of Communications."

"Yes," I said, realizing in what high esteem that mystery-man of millions was held.

"I do not think I would care to have such colossal wealth as his," remarked the Chief of Police. "As soon as he arrived from Paris I had orders from the Ministry to place him under surveillance, because, it seems, he goes in fear of some personal attack upon him."

"By whom?" I asked, instantly interested.

"The information is vague," was his reply. Then, taking up a large yellow paper from his desk, he said: "It seems that he has applied to the Ministry for personal protection, and for a daily report of anyone who may be keeping observation upon him. There is a young Englishman living at the Palace Hotel who seems unduly interested in the gentleman's movements. We are watching him."

I held my breath. This was an unexpected revelation. De Gex was in fear of us, and had resorted to that ruse in order to keep himself posted upon Hambledon's movements! Truly the situation was daily growing more complicated!

"Surely such a well-known man as Mr. De Gex--a man who is noted not only for his immense wealth, but for his generous contributions to charity--could not have enemies?" I remarked.

"Everyone has enemies, my dear m'sieur," was the police official's suave reply. "Señor De Gex was here in Madrid a year ago when he made a similar application to the Ministry for personal surveillance. He was here in connexion with the foundation of the new Madrid and Southern Spain Banking Corporation, which is guaranteed by a group of French and Dutch financiers of whom Señor De Gex is the head."

He paused, and then continued:

"He seems highly strung and nervous. All men who are in the public eye seem to be the same. Well-known foreigners visiting Madrid often apply for surveillance, yet there is certainly no need of it. And I confess to you that my staff is, after all, unduly worked."

"I can quite imagine that," I said. "But is a strict watch kept upon Mr. De Gex?"

"Yes, and upon his agent, Monsieur Suzor, also."

"Has Monsieur Suzor been in Madrid before?"

"He was here two years ago when Señor De Gex had some big financial deal with the Count Chamartin, who was head of the Miramar Shipping Company of Barcelona. They say he bought the whole fleet of steamers from Count Chamartin."

"Was Count Chamartin wealthy?"

"Yes. A millionaire, without a doubt. But it is said that shortly before his death he quarrelled with his wife. Why, nobody knows. She lives at Segovia, and their house here in the capital has just been sold."

"Was any attempt made upon Mr. De Gex?" I asked.

"Well, a mysterious young Frenchman called one night at the Ritz and demanded to see him. He was very excited, and when he was refused admission upstairs, he flourished a revolver. My agent on duty arrested the stranger, who was, after examination, deported. For that Señor De Gex sent me a letter of thanks, and the scarf-pin which you see I wear."

The pin he indicated consisted of a single black pearl with the base surrounded by diamonds, an expensive piece of jewellery. That, in itself, was sufficient to show that Oswald De Gex was a past-master in the art of bribery, and that he had established in the minds of the authorities of the Spanish capital that when he came there he came in the interests of the Government, and hence he could do no wrong.

Ah! How I longed to be able to tell my story to that charming official. But I saw that if I did so he would not only disbelieve me, but put me down as an exaggerating fool. So I held my tongue.

I further questioned him concerning De Gex and his friend Suzor.

"Monsieur Suzor has been in Madrid before," he said. "He is agent of Señor De Gex. But how wealthy the latter must be! During the war he made a big loan to our Government. The real extent of it is not known, but some say that he can pull the strings of the Cabinet in any way he wishes, though the King disapproved of the whole transaction. At least that is the rumour. Yet, after all, Señor De Gex is a true friend of Spain, even though he, like all financiers, obtains huge percentages upon his loans."

"True," I laughed. "Men of wealth are seldom philanthropists. One finds more true philanthropy among the poor, and in the artistic circles of lower Bohemia, than in the circles of the ultra-rich. Philanthropy is not written in the dictionary of the war-rich--those blatant profiteers with their motors and their places in the country, who, having fattened upon the lives of the brave fellows who fought and died to save Europe from the unholy Hun, are now enjoying their lives, while the widows and orphans of heroes starve."

"Ah, M'sieur Garfield, with that I entirely agree," sighed the astute man seated at his writing-table with the three telephones at his elbow. "In my official career as head of the police department of Madrid, I have watched recent events, and I have seen how men who were little removed from the category of the worst criminals, have suddenly jumped into wealth, with its consequent notoriety, and the power which is inseparable from the possessor of money."

"The international financier Oswald De Gex is one of those," I said. "You cannot close your eyes to that fact!"

"You appear to entertain some antipathy towards him," he remarked, a little surprised it seemed.

"No, not at all," I assured him, smiling. "I only speak broadly. All these great financiers fatten upon the ruin of honest folk."

"I hardly think that such is the case with Señor De Gex," he remarked. "But you are English, and you probably know more than myself concerning his career."

"Nobody in England knows much about him," was my reply. "We only know that he is immensely wealthy, and that his riches are daily increased by the various ventures which he finances."

"He is a great support to our Ministry of Finance," declared the Chief of Police. "It was Count Chamartin who first interested him in Spain, I believe. In any case, they combined to finance a number of industrial enterprises, including the great Guadajoz Copper Mine which must, in itself, have brought them both a fortune."

"You said that the count is dead," I remarked.

"Yes. He died quite suddenly last year. He was one of the most popular men at Court, and his tragic death caused a great sensation. He was taken ill in the Sud Express while travelling from Madrid to keep an appointment with Señor De Gex in Paris, and though he was taken from the train on its arrival at San Sebastian and conveyed to the hospital, he died a few moments after reaching there. He had a weak heart, and had consulted two doctors only a month previously. They had ordered him a complete rest and change, but, contrary to their advice, he continued attending to his affairs--with fatal result."

"And the countess?"

"Ah! Poor lady, she was beside herself with grief. She was his second wife. His first was the daughter of an Englishman who lived in Madrid. The present countess is the daughter of the Marquis Avellanosa of Algeciras, and they were a most devoted pair. She now lives in Segovia in comparative seclusion. The count's untimely end was a great loss to Spain."

It was news to me that Oswald De Gex was in Madrid with his agent Suzor in connexion with the new railway scheme. Indeed, what I had just been told was all amazing, and showed De Gex to be a man of outstanding genius. The mystery-man of Europe took good care to inform himself of any person who watched his movements, or sought to inquire into his business. It certainly was a master-stroke to pretend fear of assassination, and compel the police to act as his personal guard. By that means he had learnt that Hambledon and myself were in Madrid on purpose to discover what we could, hence he had hired the assassin Despujol to set that dastardly trap for me.

Again it was upon the tip of my tongue to reveal the suspicions I had of the great financier, but I refrained, because I could see that my companion held De Gex in high esteem as a friend and financial mainstay of his country.

A few moments later I reverted to the possibility of the arrest of Despujol, for if arrested he might betray De Gex as the person who had paid him to place those infected pins in my room. In such case my story would be heard and investigated.

But the Chief of Police shook his head dubiously.

"I fear that he has again gone into safe hiding--up in the mountains somewhere, without a doubt," he replied. "It was an act of considerable daring to come boldly to Madrid and stay at your hotel when he knows full well the hue-and-cry for him is raised everywhere, and that there is actually ten thousand pesetas offered as reward for his capture."

"Someone may betray him," I suggested with a smile.

"Yes. We hope so. One of his friends, male or female, will no doubt do so and come one day to us for the reward. Not till then shall we know the truth of that strange attempt upon your life. The motive could not have been robbery, as you had nothing worth taking save your watch. If he had been found in De Gex's room at the Ritz one could have understood it."

I smiled. The Chief of Police never suspected the true facts of the case, facts within my own knowledge, which were of such an amazing and startling character that I hesitated to relate them.

When I left my friend I again sought Hambledon and told him all I had learnt.

"H'm!" he grunted. "Very wily of De Gex to get the police to keep an eye upon me. If I'm not careful I shall suddenly find myself under arrest as a suspicious person who is in the habit of loitering in the vicinity of the great financier."

"Yes," I agreed. "This seems to put an end to our present activity--does it not?"

"Well, he apparently knows that we are watching," Hambledon said. "What a pity we cannot tell the police all we know."

"If we did we should not be believed, and, moreover, they wouldn't hear a word against the great man who is such a friend to Spain. Money buys reputation, remember. Nobody knows that better than De Gex."

Hambledon was standing at my bedroom window looking thoughtfully down upon the Puerta del Sol with its crowd of hurrying foot-passengers.

"It seems a miserable ending to all our careful surveillance upon Suzor--doesn't it?" he grumbled.

"True, it does. But now that the pair are on the alert I cannot see that anything can be gained by remaining in Madrid longer," I pointed out.

"Then you intend to give up the quest for the truth?"
