On leaving Leghorn I had given up all hope of tracing the mysterious yachtsman, and had left the matter in the hands of the Italian police. But, without any effort on my own part, I seemed to have been drawn into a veritable network of strange incidents, all of which combined to form the most complete and remarkable enigma ever presented in life. Surely no man was ever confronted by so many mysteries at one time as I was at this moment.

Fortunately I had been careful not to show my hand to anyone, and this perhaps gave me a distinct advantage. On my journey back to London, as the train swung through Peterborough and out across the rich level lands towards Hitchin, I recollected Jack Durnford's words when I had mentioned the Lola. What, I wondered, did he know?

Next month, in November, he was due back in London after his three years' service on the Mediterranean station. Then we should meet in a few weeks I hoped. Would he tell me anything when he became aware of all I knew? He held some secret knowledge. Was it possible that his secret was the same as that held by the unfortunate girl in far-off, dreary Finland?

I called at the house in Cork Street indicated by Elma, and learned from the old commissionaire who acted as lift-man and porter, that Mr. Woodroffe's chambers were closed.

"'E's nearly always away, sir-abroad, I think," was all I could get out of the old soldier, who, like his class, was no doubt well paid to keep his mouth closed.

For two days I lounged about Westbourne Grove watching Ferrari's restaurant. In such a busy, bustling thoroughfare, with so many shop windows as excuses for loitering, the task was easy. I saw that Olinto came regularly at ten o'clock in the morning, worked hard all day, and left at nine o'clock at night, taking an omnibus home from Royal Oak. His exterior was calm and unconcerned, unlike that of a man whose devoted wife had disappeared.

I would have approached him and explained the ghastly truth, had it not been for the fact that the poor woman's body was missing.

Those September days were full of anxiety for me. Alone and unaided I was trying to solve one of the greatest of problems, plunged as I was in a veritable sea of mystery. I wanted to see Muriel Leithcourt, and to question her further regarding Elma Heath. Therefore again I left Euston, and, traveling through the night, took my seat at the breakfast-table at Greenlaw next morning.

Sir George, who was sitting alone-it not being my aunt's habit to appear early-welcomed me, and then in his bluff manner sniffed and exclaimed:

"Nice goings on up at Rannoch! Have you heard of them?"

"No. What?" I cried breathlessly, staring at him.

"Well, my suspicions that those Leithcourts were utter outsiders turns out to be about correct."

"Why?"

"Well, it's a very funny story, and there are a dozen different distorted versions of it," he said. "But from what I can gather the true facts are these: About seven o'clock the night before last, as Leithcourt and his house-party were dressing for dinner, a telegram arrived. Mrs. Leithcourt opened it, and at once went off into hysterics, while her husband, in a breathless hurry, slipped off his evening clothes again and got into an old blue serge suit, tossed a few things into a bag, and then went along to Muriel's room to urge her to prepare for secret flight."

"Flight!" I gasped. "What, have they gone?"

"Listen, and I'll tell you. The servants have described the whole affair down in the village, so there's no doubt about it. Leithcourt showed Muriel the telegram and urged her to fly. At first she refused, but for her father's sake was induced to prepare to accompany him. Of course, the guests were in ignorance of all this. The brougham was ordered to be ready in the stable-yard and not to go round, while Mrs. Leithcourt's maid tried to bring the lady back to her senses. Leithcourt himself, it seemed, rushed hither and thither, seizing the jewel-cases of his wife and daughter and whatever valuables he could place his hand upon, while the mother and daughter were putting on their things. As he rushed down the main staircase to the library, where his check-book and some ready cash were locked in the safe, he met a stranger who had just been admitted and shown into the room. Leithcourt closed the door and faced him. What afterwards transpired, however, is a mystery, for two hours later, after he and the two women had escaped, leaving the house-party to their own diversions, the stranger was found locked in a large cupboard and insensible. The sensation was a tremendous one. Cowan, the doctor, was called, and declared that the stranger had been drugged and was suffering from some narcotic. The servant who admitted him declared that the man had said he had an appointment with his master, and that no card was necessary. He, however, gave the name of Chater."

"Chater!" I cried, starting up. "Are you certain of that name?"

"I only know what Cowan told me," was my uncle's reply. "But do you know him?"

"Not at all. Only I've heard that name before," I said. "I knew a man out in Italy of the same name. But where is the visitor now?"

"In the hospital at Dumfries. They took him there in preference to leaving him alone at Rannoch."

"Alone?"

"Of course. Everyone has left, now the host and hostess have slipped off without saying good-bye. Scandalous affair, isn't it? But, my boy, you'll remember that I always said I didn't like those people. There's something mysterious about them, I feel certain. That telegram gave them warning of the visit of the man Chater, depend upon it, and for some reason they're afraid of him. It would be interesting to know what transpired between the two men in the library. And these are people who've been taken up by everybody-mere adventurers, I should call them!" And old Sir George sniffed again at thought of such scandal happening in the neighborhood. "If Gilrae must let Rannoch, then why in the name of Fortune doesn't he let it to respectable folk and not to the first fellow who answers his advertisement in The Field? It's simply disgraceful!"

"Certainly, it is a most extraordinary story," I declared. "Leithcourt evidently wished to escape from his visitor, and that's why he drugged him."

"Why he poisoned him, you mean. Cowan says the fellow is poisoned, but that he'll probably recover. He is already conscious, I hear."

I resolved to call on the doctor, who happened to be well known to me, and obtain further particulars. Therefore at eleven o'clock I drove into Dumfries and entered his consulting-room.

He was a spare, short, fair man, a trifle bald, and when I was shown in he welcomed me warmly, speaking with his pronounced Galloway accent.

"Well, it is a very mysterious case, Mr. Gregg," he said, after I had told him the object of my visit. "The gentleman is still in the hospital, and I have to keep him very quiet. He was poisoned without a doubt, and has had a very narrow escape of his life. The police got wind of the affair, and Mackenzie called to question him. But he refused to make any statement whatever, apparently treating the affair very lightly. The police, however, are mystified as to the reason of Mr. Leithcourt's sudden flight, and are anxious to get at the bottom of the curious affair."

"Naturally. And more especially after the tragedy up in Rannoch Wood a short time ago," I said.

"That's just it," said the doctor, removing his pince-nez and rubbing them. "Mackenzie seems to suspect some connection between Leithcourt's sudden disappearance and that mysterious affair. It seems very evident that the telegram was a warning to Leithcourt of the man Chater's intention of calling, and that the last-named was shown in just at the moment when the fugitive was on the point of leaving."

"Chater." I echoed. "Do you know his Christian name?"
