"You'll understand when I tell you the story." And then, standing together beneath the awning, I related to my friend the whole of the curious circumstances, just as I have recorded them in the foregoing pages.

"Confoundedly funny!" he remarked with his dark eyes fixed upon mine. "A mystery, by Jove, it is! What name did the yacht bear?"

"The Lola."

"What!" he gasped, suddenly turning pale. "The Lola? Are you quite sure it was the Lola–L-O-L-A?"

"Absolutely certain," I replied. "But why do you ask? Do you happen to know anything about the craft?"

"Me!" he stammered, and I could see that he had involuntarily betrayed the truth, yet for some reason he wished to conceal his knowledge from me. "Me! How should I know anything about such a craft? They were thieves on board evidently-perhaps pirates, as you say."

"But the name Lola is familiar to you, Jack! I'm sure it is, by your manner."

He paused a moment, and I could see what a strenuous effort he was making to avoid betraying knowledge.

"It's-well-" he said hesitatingly, with a rather sickly smile. "It's a girl's name-a girl I once knew. The name brings back to me certain memories."

"Pleasant ones-I hope."

"No. Bitter ones-very bitter ones," he said in a hard tone, striding across the deck and back again, and I saw in his eyes a strange look, half of anger, half of deep regret.

Was he telling the truth, I wondered? Some tragic romance or other concerning a woman had, I knew, overshadowed his life in the years before we had become acquainted. But the real facts he had never revealed to me. He had never before referred to the bitterness of the past, although I knew full well that his heart was in secret filled by some overwhelming sorrow.

Outwardly he was as merry as the other fellows who officered that huge floating fortress; on board he was a typical smart marine, and on shore he danced and played tennis and flirted just as vigorously as did the others. But a heavy heart beat beneath his uniform.

When he returned to where I stood I saw that his face had changed: it had become drawn and haggard. He bore the appearance of a man who had been struck a blow that had staggered him, crushing out all life and hope.

"What's the matter, Jack?" I asked. "Come! Tell me-what ails you?"

"Nothing, my dear old chap," he answered hoarsely. "Really nothing-only a touch of the blues just for a moment," he added, trying hard to smile. "It'll pass."

"What I've just told you about that yacht has upset you. You can't deny it"

He started. His mouth was, I saw, hard set. He knew something concerning that mysterious craft, but would not tell me.

The sound of a bugle came from the further end of the ship, and immediately men were scampering along the deck beneath as some order or other was being obeyed with that precision that characterizes the "handy man."

"Why are you silent?" I asked slowly, my eyes fixed upon my friend the officer. "I have told you what I know, and I want to discover the motive of the visit of those men, and the reason they opened Hutcheson's safe."

"How can I tell you?" he asked in a strained, unnatural voice.

"I believe you know something concerning them. Come, tell me the truth."

"I admit that I have certain grave suspicions," he said at last, standing astride with his hands behind his back, his sword trailing on the white deck. "You say that the yacht was called the Lola–painted gray with a black funnel."

"No, dead white, with a yellow funnel."

"Ah! Of course," he remarked, as though to himself. "They would repaint and alter her appearance. But the dining saloon. Was there a long carved oak buffet with a big, heavy cornice with three gilt dolphins in the center-and were there not dolphins in gilt on the backs of the chairs-an armorial device?"

"Yes," I cried. "You are right. I remember them! You've surely been on board her!"

"And there is a ladies' saloon and a small boudoir in pink beyond, while the smoking-room is entirely of marble for the heat?"

"Exactly-the same yacht, no doubt! But what do you know of her?"

"The captain, who gave his name to you as Mackintosh, is an undersized American of a rather low-down type?"

"I took him for a Scotsman."

"Because he put on a Scotch accent," he laughed. "He's a man who can speak a dozen languages brokenly, and pass for an Italian, a German, a Frenchman, as he wishes."

"And the-the man who gave his name as Philip Hornby?"

Durnford's mouth closed with a snap. He drew a long breath, his eyes grew fierce, and he bit his lip.

"Ah! I see he is not exactly your friend," I said meaningly.

"You are right, Gordon-he is not my friend," was his slow, meaning response.

"Then why not be outspoken and tell me all you know concerning him? Frank Hutcheson is anxious to clear up the mystery because they've tampered with the Consular seals and things. Besides, it would be put down to his credit if he solved the affair."

"Well, to tell you the truth, I'm mystified myself. I can't yet discern their motive."

"But at any rate you know the men," I argued. "You can at least tell us who they really are."

He shook his head, still disinclined, for some hidden reason, to reveal the truth to me.

"You saw no woman on board?" he asked suddenly, looking straight into my eyes.

"No. Hornby told me that he and Chater were alone."

"And yet an hour after you left a man and a woman came ashore and disappeared! Ah! If we only had a description of that woman it would reveal much to us."

"She was young and dark-haired, so the detective says. She had a curious fixed look in her eyes which attracted him, but she wore a thick motor veil, so that he could not clearly discern her features."

"And her companion?"

"Middle-aged, prematurely gray, with a small dark mustache."

Jack Durnford sighed and stroked his chin.

"Ah! Just as I thought," he exclaimed. "And they were actually here, in this port, a week ago! What a bitter irony of fate!"

"I don't understand you," I said. "You are so mysterious, and yet you will tell me nothing!"

"The police, fools that they are, have allowed them to escape, and they will never be caught now. Ah! you don't know them as I do! They are the cleverest pair in all Europe. And they have the audacity to call their craft the Lola–the Lola, of all names!"

"But as you know who and what the fellows are, you ought, I think, in common justice to Hutcheson, to tell us something," I complained. "If they are adventurers, they ought to be traced."

"What can I do-a prisoner here on board?" he argued bitterly. "How can I act?"

"Leave it all to me. I'm free to travel after them, and find out the truth if only you will tell me what you know concerning them," I said eagerly.

"Gordon, let me be frank and open with you, my dear old fellow. I would tell you everything-everything-if I dared. But I cannot-you understand!" And his final words seemed to choke him.

I stood before him, open-mouthed in astonishment.

"You really mean-well, that you are in fear of them-eh?" I whispered.

He nodded slowly in the affirmative, adding: "To tell you the truth would be to bring upon myself a swift, relentless vengeance that would overwhelm and crush me. Ah! my dear fellow, you do not know-you cannot dream-what brought those desperate men into this port. I can guess-I can guess only too well-but I can only tell you that if you ever do discover the terrible truth-which I fear is unlikely-you will solve one of the strangest and most remarkable mysteries of modern times."

"What does the mystery concern?" I asked, in breathless eagerness.

"It concerns a woman."
