I was astounded, and relaxed my hold! What was the little craven clerk doing there at this time of night, and in such weather?

"What——" I began, when he uttered an exclamation of terror, as it seemed.

"Dr. Phillimore!"

"That is so," I answered. "What on earth are you doing here?"

There was almost a whimper in his voice as he replied:

"The fog, doctor. I was foolish enough to wander out on the deck, and I lost my way. I've been straying about for twenty minutes or more. I couldn't find the door again."

"Well, you won't in this direction," I assured him. "This part of the country belongs to the enemy. You've strayed afield, my friend, so, if you'll give me your arm, I'll do my best to put you straight."

He thanked me, and did as I asked him, but, as I thought, somewhat timorously. His hand rested nervously inside my arm, as if he would have withdrawn it and fled at a moment's notice. And so we stumbled along the deck together to the state cabins.

I gave the signal on the door, and we were admitted by Ellison. There was no one else in the corridor except Lane at the farther end, and, to my surprise, the Princess. She was seated on a couch under the electric light, reading, clad in a long and flowing morning-gown. Her hand with the book had dropped a little as we entered, and her eyes sought us.

"There will be no alarm to-night, Ellison," I said on the spur of the moment, and I caught the Princess's eye. She rose, shut her book, and came towards us.
