Again that unpleasantly sounding snigger.

"I hope you're not feeling nervous; you needn't. That signal is not far off, and when we reach it we are out in the open. I know exactly where we are; this is Redhill tunnel. Not only can I see in the dark, dimly, but still see, but I also have, in a curious degree, the bump of locality. With me it amounts almost to an additional sense. I always know where I am, even when I am in a strange place; in a place in which I have been before I have an incredible perception of my surroundings. For three years I lived quite close to this--in Earlswood Asylum, as a patient."

Earlswood Asylum! Then the creature was a lunatic. That explained the singularity of his voice, of his manner, his proceedings. An idea came into Rodney's head. The creature was small; he felt, as he moved beside him with his hand under his arm, that he probably did not reach to his shoulder. It would be easy to leave him in the tunnel. Who cares what happens to a lunatic?

"I shouldn't if I were you; it wouldn't pay."

The words were so apposite that, despite himself, Rodney started. He had not spoken. Could the creature read what was passing through his brain?

"There are times when I can read people's thoughts just as plainly as if they had spoken them out loud, even when I can't see their faces--really! Isn't it odd? Oh, I am quite gifted. My argument always has been that, in a general way, a lunatic is merely abnormal, nothing more. At intervals a cloud settles on my brain; I can see, I can feel it coming; then, for an indefinite period, I am on the lap of the gods. When it passes my senses are more acute than other people's--abnormally acute, I know it as a fact. Now you see, as I told you, we are out in the open--look! the stars are shining. Look back at the tunnel; isn't it a horror of blackness? Like the horror I know. If we scramble up that bank we shall probably find a gap in the hedge at the top; platelayers often do leave a gap in a hedge close to the wall of a tunnel that they may descend to the line. As I told you, here's our gap; now, over the fence, and the rest is easy sailing."

It seemed to Rodney that since he had quitted the train something must have happened to him mentally; it was as if, all at once, he were playing a part in a dream. In silence, without offering the least remonstrance, he had suffered the stranger to pilot him out of the tunnel, up the steep bank beyond--to dominate him wholly. Now, except that they seemed to be standing in an open space of considerable size, he had not the dimmest notion of their whereabouts; but to the stranger it all seemed plain.

"That big building on our right's an orphanage--St. Anne's; I believe we're on their ground. If we keep straight on to our left we shall come to the high road, from which it is only a few minutes to Redhill station, whence we shall continue our journey to town. Quite an interesting episode this has been, has it not? I am indebted to you for much entertainment. I have seldom had so much enjoyment in a train, Mr. Elmore."

The creature knew his name! How? Who was he? What did it mean? Again he was conscious of an impulse to take him by the throat and--resolve the question in his own fashion. How came the creature to know his name? Although he had uttered no articulate sound, he had his answer.

"The explanation is simple, explanations often are. I heard your uncle address you by your name in a most audible tone of voice just towards the close. Most people have no idea how thin the partition really is which divides one compartment from another. Do you know I have heard that in some instances it is made of papier-mâché--fancy! You can always hear if a conversation is taking place in an adjoining compartment--it is surprising how much you can hear if you try, especially if your hearing is as good as mine is--that's another of my gifts. I had my ear glued to the partition most of the time. Of course, I could not hear everything--and I should very much have liked to see, but I gathered enough to enable me to form a general idea, particularly when you began to use violence towards your uncle and to hurl him back into his seat--it amounted to hurling. You see, I was his side. And, of course, when you both raised your voices I could hear a very great deal. I was not in the least surprised at the silence which followed. I understood--oh, I understood! At least, I think I understood. It was perfectly plain that only one person was left in the compartment who counted, and, of course, I knew that was you. I said to myself: 'Now, I wonder how long he'll stay there all alone? He's sure to take advantage of the first opportunity of getting out if the train stops or slows, and if he gets out I'll get out too.' Wasn't it lucky that it stopped in a tunnel, and that, therefore, we were both of us able to get out without being observed? Quite a stroke of fortune! Here we are, right on the high road, with the station a little more than a stone's throw in front of us."
