lighthouse of St. 
Elmo looming more vividly every moment. As soon as we were at 
anchor and the gangway down, I hailed one of the little green boats and 
told the men to row me to the shore. I drove at once to the Grand Hotel
in the Strada Reale, and asked the Italian guide the address of a medical 
man. He gave me the address of an English doctor who lived close by, 
and I went there at once to see him. It was now seven o'clock, and I 
found him up. I made my apologies for the early hour of my visit, put 
the whole matter before him, and produced the syringe. For a moment 
he was inclined to take my story with incredulity, but by degrees he 
became interested, and ended by inviting me to breakfast with him. 
After the meal we repaired to his consulting-room to make our 
investigations. He brought out his microscope, which I saw, to my 
delight, was of the latest design, and I set to work at once, while he 
watched me with evident interest. At last the crucial moment came, and 
I bent over the instrument and adjusted the focus on my preparation. 
My suspicions were only too well confirmed by which I had extracted 
what I saw. The substance from the syringe was a mass of 
micro-organisms, but of what nature I did not know. I had never seen 
any quite like them before. I drew back. 
"I wish you would look at this," I said. "you tell me you have devoted 
considerable attention to bacteriology. Please tell me what you see." 
Dr. Benson applied his eye to the instrument, regulating the focus for a 
few moments in silence, then he raised his head, and looked at me with 
a curious expression. 
"Where did this culture come from?" he asked. 
"From London, I presume," I answered. 
"It is extraordinary," he said, with emphasis, "but there is no doubt 
whatever that these organisms are the specific germs of the very disease 
I have studied here so assiduously ; they are the micrococci of 
Mediterranean fever, the minute round or oval bacteria. They are 
absolutely characteristic." 
I jumped to my feet. 
"Is that so?" I cried. The diabolical nature of the plot was only too plain. 
These germs injected into a patient would produce a fever which only
occurs in the Mediterranean. The fact that the boy had been in the 
Mediterranean even for a short time would be a complete blind as to the 
way in which they obtained access to the body, as every one would 
think the disease occurred from natural causes. 
"How long is the period of incubation?" I asked. 
"About ten days," replied Dr. Benson. 
I extended my hand. 
"You have done me an invaluable service," I said. 
"I may possibly be able to do you a still further service," was his reply. 
"I have made Mediterranean fever the study of my life, and have, I 
believe, discovered an antitoxin for it. I have tried my discovery on the 
patients of the naval hospital with excellent results. The local 
disturbance is slight, and I have never found bad symptoms follow the 
treatment. If you will bring the boy to me I will administer the antidote 
without delay." 
I considered for a moment, then I said: "My position is a terrible one, 
and I am inclined to accept your proposition. Under the circumstances 
it is the only chance." 
"It is," repeated Dr. Benson. "I shall be at your service whenever you 
need me." 
I bade him good-bye and quickly left the house. 
It was now ten o'clock. My first object was to find Dr. Fietta, to speak 
to him boldly, and take the boy away by main force if necessary. I 
rushed back to the Grand Hotel, where I learned that a boy and a man, 
answering to the description of Dr. Fietta and Cecil, had breakfasted 
there, but had gone out again immediately afterwards. The Hydaspes I 
knew was to coal, and would not leave Malta before one o'clock. My 
only chance, therefore, was to catch them as they came on board. Until 
then I could do nothing. At twelve o'clock I went down to the quay and
took a boat to the Hydaspes. Seeing no sign of Fietta and the boy on 
deck, I made my way at once to Lord Kairn's cabin. The door was open 
and the place in confusion Ñ every vestige of baggage had disappeared. 
Absolutely at a loss to divine the cause of this unexpected discovery, I 
pressed the electric bell. In a moment a steward appeared. 
"Has Lord Kairn left the ship?" I asked, my heart beating fast. 
"I believe so, sir," replied the man. "I had orders to pack the luggage 
and
