"The fact is," I said confidentially, "you must omit me from the witnesses at the inquest."

"Why?" asked the detective suspiciously.

"Because if it were known that I have identified him, all chance of getting at the truth will at once vanish," I answered. "I have come here to tell you in strictest confidence who the poor fellow really is."

"Then you know something of the affair?" he said, with a strong Highland accent.

"I know nothing," I declared. "Nothing except his name."

"H'm. And you say he's a foreigner-an Italian-eh?"

"He was in my service in Leghorn for several years, and on leaving me he came to London and obtained an engagement as waiter in a restaurant. His father lived in Leghorn; he was doorkeeper at the Prefecture."

"But why was he here, in Scotland?"

"How can I tell?"

"You know something of the affair. I mean that you suspect somebody, or you would have no objection to giving evidence at the inquiry."

"I have no suspicions. To me the affair is just as much of an enigma as to you," I hastened at once to explain. "My only fear is that if the assassin knew that I had identified him he would take care not to betray himself."

"You therefore think he will betray himself?"

"I hope so."

"By the fact that the man was attacked with an Italian stiletto, it would seem that his assailant was a fellow-countryman," suggested the detective.

"The evidence certainly points to that," I replied.

"You don't happen to be aware of anyone-any foreigner, I mean-who was, or might be his enemy?"

I responded in the negative.

"Ah," he went on, "these foreigners are always fighting among themselves and using knives. I did ten years' service in Edinburgh and made lots of arrests for stabbing affrays. Italians, like Greeks, are a dangerous lot when their blood is up." Then he added: "Personally, it seems to me that the murdered man was enticed from London to that spot and coolly done away with-from some motive of revenge, most probably."

"Most probably," I said. "A vendetta, perhaps. I live in Italy, and therefore know the Italians well," I added.

I had given him my card, and told him with whom I was staying.

"Where were you yesterday, sir?" he inquired presently.

"I was shooting-on the other side of the Nithsdale," I answered, and then went on to explain my movements, without, however, mentioning my visit to Rannoch.

"And although you know the murdered man so intimately, you have no suspicion of anyone in this district who was acquainted with him?"

"I know no one who knew him. When he left my service he had never been in England."

"You say he was engaged in service in London?"

"Yes, at a restaurant in Oxford Street, I believe. I met him accidentally in Pall Mall one evening, and he told me so."

"You don't know the name of the restaurant?"

"He did tell me, but unfortunately I have forgotten."

The detective drew a deep breath of regret.

"Someone who waited for him on the edge of that wood stepped out and killed him-that's evident," he said.

"Without a doubt."

"And my belief is that it was an Italian. There were two foreigners who slept at a common lodging-house two nights ago and went on tramp towards Glasgow. We have telegraphed after them, and hope we shall find them. Scotsmen or Englishmen never use a knife of that pattern."

With his latter remark I entirely coincided. In my own mind that was the strongest argument in favor of Leithcourt's innocence. That the tenant of Rannoch had kept that secret tryst in daily patience I knew from my own observations, yet to me it scarcely seemed feasible that he would use a weapon so peculiarly Italian and yet so terribly deadly.

And then when I reflected further, recollecting that the body I had discovered was that of a woman and not a man, I stood staggered and bewildered by the utterly inexplicable enigma.

I promised the burly detective that in exchange for his secrecy regarding my statement that I would assist him in every manner possible in the solution of the problem.

"The real name of the murdered man must be at all costs withheld," I urged. "It must not appear in the papers, for I feel confident that only by the pretense that he is unknown can we arrive at the truth. If his name is given at the inquiry, then the assassin will certainly know that I have identified him."

"And what then?"

"Well," I said with some hesitation, "while I am believed to be in ignorance we shall have opportunity for obtaining the truth."

"Then you do really suspect?" he said, again looking at me with those cold, blue eyes.

"I know not whom to suspect," I declared. "It is a mystery why the man who was once my faithful servant should be enticed to that wood and stabbed to the heart."

"There is no one in the vicinity who knew him?"

"Not to my knowledge."

"We might obtain his address in London through his father in Leghorn," suggested the officer.

"I will write to-day if you so desire," I said readily. "Indeed, I will get my friend the British Consul to go round and see the old man and telegraph the address if he obtains it."

"Capital!" he declared. "If you will do us this favor we shall be greatly indebted to you. It is fortunate that we have established the victim's identity-otherwise we might be entirely in the dark. A murdered foreigner is always more or less of a mystery."

Therefore, then and there, I took a sheet of paper and wrote to my old friend Hutcheson at Leghorn, asking him to make immediate inquiry of Olinto's father as to his son's address in London.

I said nothing to the police of that strange adventure of mine over in Lambeth, or of how the man now dead had saved my life. That his enemies were my own he had most distinctly told me, therefore I felt some apprehension that I myself was not safe. Yet in my hip pocket I always carried my revolver-just as I did in Italy-and I rather prided myself on my ability to shoot straight.

We sat for a long time discussing the strange affair. In order to betray no eagerness to get away, I offered the big Highlander a cigar from my case, and we smoked together. The inquiry would be held on the morrow, he told me, but as far as the public was concerned the body would remain as that of some person "unknown."

"And you had better not come to my uncle's house, or send anyone," I said. "If you desire to see me, send me a line and I will meet you here in Dumfries. It will be safer."

The officer looked at me with those keen eyes of his, and said:

"Really, Mr. Gregg, I can't quite make you out, I confess. You seem to be apprehensive of your own safety. Why?"

"Italians are a very curious people," I responded quickly. "Their vendetta extends widely sometimes."

"Then you have reason to believe that the enemy of this poor fellow Santini may be your enemy also?"

"One never knows whom one offends when living in Italy," I laughed, as lightly as I could, endeavoring to allay his suspicion. "He may have fallen beneath the assassin's knife by giving quite a small and possibly innocent offense to somebody. Italian methods are not English, you know."

"By Jove, sir, and I'm jolly glad they're not!" he said. "I shouldn't think a police officer's life is a very safe one among all those secret murder societies I've read about."

"Ah! what you read about them is often very much exaggerated," I assured him. "It is the vendetta which is such a stain upon the character of the modern Italian; and depend upon it this affair in Rannoch Wood is the outcome of some revenge or other-probably over a love affair."

"But you will assist us, sir?" he urged. "You know the Italian language, which will be of great advantage; besides, the victim was your servant."

"Be discreet," I said. "And in return I will do my very utmost to assist you in hunting down the assassin."
