"Well, good-bye, Alexis;" and he shook hands with me.
"Good-bye," I answered with a laugh: and he waved an adieu to us from the other side of the barrier.
As we turned away together, Olga was a little pale.
Three soldiers saluted me, and I acknowledged the salute gravely, glancing at them as I passed.
Then I noticed a couple of men who had been standing together and watching the girl and myself for some time, leave their places and follow us. I told my companion and presently I saw her turn and look at them, and then start and shiver.
"Do you know them?" I asked.
"Alas, yes. They are Nihilist spies, watching us."
"Ah, then there is a little more in this than I have understood so far," I said.
"You shall know everything," she replied as we left the station together.
