Turnbull thrust his first finger down the aperture, and at last managed to make a slight further fissure in the piping. The light that came up from beyond was very faint, and apparently indirect; it seemed to fall from some hole or window higher up. As he was screwing his eye to peer at this grey and greasy twilight he was astonished to see another human finger very long and lean come down from above towards the broken pipe and hook it up to something higher. The lighted aperture was abruptly blackened and blocked, presumably by a face and mouth, for something human spoke down the tube, though the words were not clear.
“Who is that?” asked Turnbull, trembling with excitement, yet wary and quite resolved not to spoil any chance.
After a few indistinct sounds the voice came down with a strong Argyllshire accent:
“I say, Turnbull, we couldn’t fight through this tube, could we?”
Sentiments beyond speech surged up in Turnbull and silenced him for a space just long enough to be painful. Then he said with his old gaiety: “I vote we talk a little first; I don’t want to murder the first man I have met for ten million years.”
“I know what you mean,” answered the other. “It has been awful. For a mortal month I have been alone with God.”
Turnbull started, and it was on the tip of his tongue to answer: “Alone with God! Then you do not know what loneliness is.”
But he answered, after all, in his old defiant style: “Alone with God, were you? And I suppose you found his Majesty’s society rather monotonous?”
“Oh, no,” said MacIan, and his voice shuddered; “it was a great deal too exciting.”
After a very long silence the voice of MacIan said: “What do you really hate most in your place?”
“You’d think I was really mad if I told you,” answered Turnbull, bitterly.
“Then I expect it’s the same as mine,” said the other voice.
“I am sure it’s not the same as anybody’s,” said Turnbull, “for it has no rhyme or reason. Perhaps my brain really has gone, but I detest that iron spike in the left wall more than the damned desolation or the damned cocoa. Have you got one in your cell?”
“Not now,” replied MacIan with serenity. “I’ve pulled it out.”
His fellow-prisoner could only repeat the words.
“I pulled it out the other day when I was off my head,” continued the tranquil Highland voice. “It looked so unnecessary.”
“You must be ghastly strong,” said Turnbull.
“One is, when one is mad,” was the careless reply, “and it had worn a little loose in the socket. Even now I’ve got it out I can’t discover what it was for. But I’ve found out something a long sight funnier.”
“What do you mean?” asked Turnbull.
“I have found out where A is,” said the other.
Three weeks afterwards MacIan had managed to open up communications which made his meaning plain. By that time the two captives had fully discovered and demonstrated that weakness in the very nature of modern machinery to which we have already referred. The very fact that they were isolated from all companions meant that they were free from all spies, and as there were no gaolers to be bribed, so there were none to be baffled. Machinery brought them their cocoa and cleaned their cells; that machinery was as helpless as it was pitiless. A little patient violence, conducted day after day amid constant mutual suggestion, opened an irregular hole in the wall, large enough to let in a small man, in the exact place where there had been before the tiny ventilation holes. Turnbull tumbled somehow into MacIan’s apartment, and his first glance found out that the iron spike was indeed plucked from its socket, and left, moreover, another ragged hole into some hollow place behind. But for this MacIan’s cell was the duplicate of Turnbull’s–a long oblong ending in a wedge and lined with cold and lustrous tiles. The small hole from which the peg had been displaced was in that short oblique wall at the end nearest to Turnbull’s. That individual looked at it with a puzzled face.
“What is in there?” he asked.
MacIan answered briefly: “Another cell.”
“But where can the door of it be?” said his companion, even more puzzled; “the doors of our cells are at the other end.”
“It has no door,” said Evan.
In the pause of perplexity that followed, an eerie and sinister feeling crept over Turnbull’s stubborn soul in spite of himself. The notion of the doorless room chilled him with that sense of half-witted curiosity which one has when something horrible is half understood.
“James Turnbull,” said MacIan, in a low and shaken voice, “these people hate us more than Nero hated Christians, and fear us more than any man feared Nero. They have filled England with frenzy and galloping in order to capture us and wipe us out–in order to kill us. And they have killed us, for you and I have only made a hole in our coffins. But though this hatred that they felt for us is bigger than they felt for Bonaparte, and more plain and practical than they would feel for Jack the Ripper, yet it is not we whom the people of this place hate most.”
A cold and quivering impatience continued to crawl up Turnbull’s spine; he had never felt so near to superstition and supernaturalism, and it was not a pretty sort of superstition either.
“There is another man more fearful and hateful,” went on MacIan, in his low monotone voice, “and they have buried him even deeper. God knows how they did it, for he was let in by neither door nor window, nor lowered through any opening above. I expect these iron handles that we both hate have been part of some damned machinery for walling him up. He is there. I have looked through the hole at him; but I cannot stand looking at him long, because his face is turned away from me and he does not move.”
Al Turnbull’s unnatural and uncompleted feelings found their outlet in rushing to the aperture and looking into the unknown room.
It was a third oblong cell exactly like the other two except that it was doorless, and except that on one of the walls was painted a large black A like the B and C outside their own doors. The letter in this case was not painted outside, because this prison had no outside.
