"It's just this, Sir Roland," I said at last, bracing myself to face an unpleasant task. "You, Dulcie, and I too, have been completely taken in by Mrs. Stapleton. We believed her to be as charming as she certainly is beautiful, we thought she was a lady, we"

"'Thought'!" Sir Roland interrupted, cold with anger. "I still consider her to be"

"Will you let me finish? I say we all thought that, I say we supposed that Mrs. Stapleton was just one of ourselves, a lady, an ordinary member of society. Then circumstances arose, events occurred which aroused my suspicions. At first I tried to dispel those suspicions, not only because I liked the woman personally, but because it seemed almost incredible that such a woman, mixing with the right people, received everywhere, could actually be what the circumstances and events I have hinted at pointed to her being. But at last proof came along that Mrs. Stapleton wasas she is stilla common adventuress, or rather an uncommon adventuress, a prominent member of a gang of clever thieves, of a clique of criminals"

"Criminals!" Sir Roland stormed, bursting suddenly into passion. Often I had seen him annoyed, but never until now had I seen him actually in an ungovernable fury. "How dare you say the lady I am about to marry isis"

"I have proofs, Sir Roland," I cut in as calmly as I could. "You may doubt my word, you can hardly doubt the word of a famous Continental detective. He is on board. I will bring him here now."

As I quietly rose to leave the room, I saw Sir Roland staring, half stupidly, half in a passion still, from Dulcie to me, then back again at Dulcie. Before he could speak, however, I had left the little room and gone in search of Victor Albeury. He was not in his cabin, nor was he in the smoking-room, where men still sat playing cards, nor was he in the big saloon. On the forward deck I found him at last, a solitary figure leaning against the stanchion rail, smoking his pipe, and gazing abstractedly out across the smooth sea, his eyes apparently focussed upon the black, far-distant horizon.

Gently I tapped him on the arm, as he seemed unaware of my approach.

"Well, Mr. Berrington," he said calmly, without looking round or moving, "what can I do for you?"

"Please come at once," I exclaimed. "Sir Roland and Miss Challoner are in the small saloon; we have been trying to explain to Sir Roland that the woman Stapleton is an adventuress. Probably you don't know that she is engaged to be married to Sir Roland. He won't believe a word we say. We want you to come to himto speak to him and open his eyes."

It was no easy matter, however, to get the old man to believe even Albeury's calm and convincing assurance that Connie Stapleton belonged to a gang of infamous people, some of whom we knew beyond question to be cold-blooded assassins. It was due, indeed, largely to Albeury's remarkable personality that in the end he succeeded in altering the opinion Sir Roland had held concerning this woman of whom he was evidently even more deeply enamoured than we already knew him to be.
