He made a rough model on the table-cloth, using some of the breakfast things for the purpose of shewing the positions of the railway and the trees.

"No one can mistake that," I said.

"Well, you are to take up your position here, you yourself, I mean, here, in a dead straight line between these two trees"—demonstrating them on the table-cloth—"for this is where there will be an accident. And now, pay close heed to this. You will go out by train; and when your men are paraded at the station they will be joined by five of ours. These will mingle with yours at the very last moment; and if any questions are asked they will produce the necessary authority. These five men you will arrange carefully to take the next five positions to you on your right hand. When the train leaves the line, they will instantly close round and guard the Emperor's carriage; and you will see that nothing prevents them. That is all you have to do; and if you act discreetly you will run no risk. You will not fail. They know their duties and will do them; and will let no one come between them and their noble task. Five bolder men do not breathe in all Russia. Remember, they are to be stationed next to you on your right. You understand?"

"Every item."

"It is a great day for you, friend," he said.

"It is a great day for Russia," I returned; and soon after he left me.

I was filled with the most anxious doubt as to what course I ought to take to checkmate this horrible plot, of which I was the most unwilling depository and was marked out as the forced agent.

During the whole day I was turning the problem over and over in my thoughts: and I could see no course that would be at all effective in thwarting the plot without at the same time exposing myself to all the hazard of being punished as a Nihilist. I could, of course, tell the police or Prince Bilbassoff, but this meant a double danger for me. They would take measures to alter the arrangements as to the visit; the reason for this would have to be told to the Czar; it would certainly leak out to the Nihilists, and I should be a mark for their assassins at once. On the other hand the story told by Paula Tueski would seem to have the corroboration which my acquaintance with Nihilist matters would give to it, and I should be in peril there.

One consideration there was that gave some reassurance. I had already had the orders for the distribution of the troops, and I knew that I was to be miles away from those cursed alder trees at the moment when the Czar would be passing. I knew too that if the plot went wrong in that main feature, it would fail altogether.

The Nihilists were not such fools as to draw down on themselves all the sensational punishments which would inevitably follow the discovery of an organised attempt on the life of the Czar, for the mere empty purpose of sending the Imperial train off the line. Unless therefore, they had some emissary so highly placed as to be in possession of the information long before any of us in Moscow knew about it, the whole machinery was likely to be stopped for the one flaw. And though I had had some proofs of the extraordinary accuracy of their information, I could not believe their power to be such as this necessitated.
