e of discovering the true facts would instantly
vanish.

"I hope you will soon be all right and that you will enjoy your visit
to our Tuscany," he said very pleasantly. "Florence is very full of
visitors just now. Are you remaining long?"

"I really can't tell," was my reply. "My business in London may recall
me at any time."

Then I thanked him for his visit, and remarked that if the mixture
gave me no relief I would probably call upon him.

Indeed, it was for this latter reason that I had called him in. By
making his acquaintance in that manner I would, I saw, excite no
suspicion, and I hoped to be able to meet the girl who was apparently
under his charge.

While I had been consulting him I noticed that he seemed a man of
curious moods. At one moment his dark countenance was sullen and
sinister, while at the next his face broadened into an expression of

"But I thought you said she lived near Detroit?" I remarked.

"She and her mother did live in America, but I have discovered that
they now have a house near Cromer," was the butler's reply. So in
acknowledgment of his services I passed him a couple of Italian
notes, and we then had a drink together.

While doing so a strange thought crossed my mind.

Could it be possible that the girl I had seen with Doctor Moroni and
Rose Thurston were one and the same!

CHAPTER THE SEVENTH

THE MILLIONAIRE'S APPREHENSIONS

That same evening I made a number of inquiries concerning Doctor
Moroni. On every hand I heard high praise of his skill. He was one of
the principal physicians at the great hospital at Gelsomino, and among
other of his illustrious patients there had been a Russian Grand Duke
and an Austrian princess who lived in a magnificent villa upon the
Viale dei Colli.

I went about the wonderful city of art collecting information
concerning the doctor, where and when I could, because a sta
