ught to be across in about half an hour from
now."

Monsieur Feurgeres engaged the best cabin on the steamer, and his
servant fitted me up a dressing-case with necessaries for the journey
from his master's ample store. Then we went into the saloon, and had
some supper. Afterwards we stood upon deck watching the passengers come
on board from the train which had just arrived. Suddenly I seized
Feurgeres by the arm and dragged him inside the cabin.

"The Princess Adelaide!" I exclaimed. "Look!"

We saw her distinctly from the window. She was dressed very plainly, and
wore a heavy veil which she had just raised. She stood within a few feet
of us, talking to the maid, who seemed to be her sole companion.

"Find my cabin, Mason," she ordered. "I shall lie down directly we
start. I am always ill upon these wretched night boats. It is a most
unpleasant arrangement, this."

Feurgeres looked at me and smiled.

"Isobel's features," he remarked, "but not her voice. You see, we are on
the right track. We must contrive to keep out of that young lady's way."

To keep out of the way of the Princess Adelaide was easy enough,
presuming that she kept her word and remained in her cabin. I watched
her enter it and close the door. Afterwards I wrapped myself in an
ulster of Feurgeres' and went out on deck. It was a fine night, but
windy, and a little dark. I lit a pipe and leaned over the side. I had
scarcely been there two minutes when I heard a light footstep coming
along the deck and pause a few feet away. A girl's voice addressed me.

"Can you tell me what that light is?"

I knew who it was at once. It was the most hideous ill-fortune. I
answered gruffly, and without turning my head.

"Folkestone Harbour!"

I thought that after that she must surely go away. But she did nothing
of the sort. She came and leaned over the rail by my side.

"You are Mr. Arnold Greatson, are you not?"

My heart sank, and I could have cursed my folly for leaving my cabin.
However, since I was discovered there was nothing to do but to make the
best of it.

"Yes, I am Arnold Greatson," I admitted.

"I wonder if you know who I am?" she asked.

"You are the Princess Adelaide of----"

She held up her hand.

"Stop, please! I see that you know. For some mysterious reason I am
travelling almost alone, and under another name which I do not like at
all. You are very fond of my cousin, Isobel, are you not,
