I put the question hesitatingly, for I knew the thoughts that were in my own mind.

"I scarcely know what to think," the other replied. "I can only confess that I am alarmed, seriously alarmed, by his prolonged absence. Woller, as you know, is a man who realises to the full the responsibilities entailed by his present position. Duty with him is more than duty, it is a matter of life and death; he knows that the eyes of England, of Europe, and I might even say of the whole world, are upon him, and for that reason alone I feel sure he would not cause us so much anxiety of his own free will."

"In that case, what do you intend doing?" I enquired, for I could well foresee the terrible trouble to which the situation would give rise. "It is now a quarter to ten, and in little more than an hour he will be expected at Waterloo. If the crowd don't see him they will begin to wonder, the man in the street will begin to talk, the newspapers will take up the tale, and in a few hours we shall have entered on a new phase of the situation."

The Commander-in-Chief rose and began to pace the room.

"I have already sent a special messenger with a letter to the Secretary of State," he replied. "In it I have told him what I fear and also what I have done. I shall consult the various heads of Departments as soon as I reach Pall Mall, on the bare chance that one of them may be able to elucidate the mystery.

"At the same time I should communicate with the railway authorities, if I were you," I continued. "I should inform them that, owing to the fact of his being detained by matters of the greatest importance, it is possible that Woller may not be able to travel by that particular train."

"That is a good idea," the Commander-in-Chief replied; "I will act upon it at once. In the event of our receiving no news, that should be sufficient to give us time to arrange some other plan. It will mean delaying the vessel at Southampton, however, and—good gracious me!—what a pile of difficulties it will land us in! The Colonial Secretary must be informed, and the matter must come before the Cabinet. As you said just now, if by any chance it should leak out and the Press get hold of it, there is no telling where it will end."

"You have communicated with Scotland Yard, of course?"

"I sent a messenger to them shortly after midnight, that is to say, as soon as I had found out that Woller had left Windsor, and that he had not been to his Club, or to his own house. Their best men are at work upon it, but so far without any satisfactory result."

"And can his own servants throw any light upon the matter?"
