Rodney listened to what the stranger had to say as, side by side, they tramped across the uneven ground with feelings which he would not have found it easy to clothe with words. Beyond all doubt this was a lunatic; but of what an uncomfortable kind! He had been wiser to have acted on his first impulse and to have left him in the tunnel. Now it was too late; it would not be the same thing to--leave him there. Yet, if he continued in his company, how should he muzzle him? With what would he make him dumb? By what means could he keep him from blurting out the whole story to the first person they might meet? Once more, though he had uttered not a syllable, there came an answer.

"You run no risk of my blabbing, I am not that kind of person--at least, while the cloud is yet afar off. Afterwards, believe me, no one pays any heed to what I say. I play the part of audience only. I am not, like you, one of Nature's criminals; but I am indifferent, which is about the same. What A does to B is A's business and B's, not mine; that I always shall maintain. Here we are at the station. It's been altered since my time; they've given it a new front. When is the next train to town?"

He put the question quite naturally to a porter who was standing about.

"Ten-forty; nearly half an hour to wait--that is if she is punctual, which she's not always of a Sunday night."

The stranger addressed himself to Elmore.

"That, perhaps, is fortunate, since that will enable me to offer you a little refreshment, of which I dare say both of us stand in need."

Rodney, always speechless, walked beside the stranger to the refreshment bar. Now he could see him plainly. A notion which had been fluttering at the back of his head took flight; there was no suggestion of a detective police official about him. He was shorter even than he had imagined, probably scarcely over five feet high; a mean-looking, ill-shapen fellow, with one shoulder higher than the other, which gave him an appearance of being one-sided. Badly dressed in an ill-fitting suit of rusty dark-grey tweed, clumsily shod, tie disarranged, doubtful collar, old tweed hat shaped like a billycock, about him the air of one who was not over fond of soap and water. Probably between fifty and sixty, a round, hairless, wizened face, all wrinkles, flat, snub nose, curiously small mouth--Rodney wondered if the peculiarity of his voice was owing to its coming through so small an aperture; queer, big, oval, ugly eyes--small pupils floating in a sea of yellow. The young gentleman was conscious of what an ill-assorted couple they must appear. He would have liked very much to put a termination to the association then and there, but--he could not, it was too late.

The stranger on his part seemed sublimely unaware of there being anything odd in their companionship. He gave his order to the young lady on the other side of the counter.

"One brandy, two Scotch whiskies, and a small soda divided."

The young lady looked as if she was not quite sure that she had caught what he said.
