"Nothing," answered Henderson; "I will wish you good-evening."
"Good-evening to you both," said the man. He made his way quickly up the path and was soon lost to sight.
Henderson and I then returned to the signal-box.
By this time it was nearly dark.
"How many trains pa.s.s in the night?" I asked of the Inspector.
"There"s the 10.20 down express," he said, "it will pa.s.s here at about 10.40; then there"s the 11.45 up, and then not another train till the 6.30 local to-morrow morning. We shan"t have a very lively time," he added.
I approached the fire and bent over it, holding out my hands to try and get some warmth into them.
"It will take a good deal to persuade me to go down to the tunnel, whatever I may see there," said the man. "I don"t think, Mr. Bell, I am a coward in any sense of the word, but there"s something very uncanny about this place, right away from the rest of the world. I don"t wonder one often hears of signalmen going mad in some of these lonely boxes.
Have you any theory to account for these deaths, sir?"
"None at present," I replied.
"This second death puts the idea of Pritchard being murdered quite out of court," he continued.
"I am sure of it," I answered.
"And so am I, and that"s one comfort," continued Henderson. "That poor girl, Lucy Ray, although she was to be blamed for her conduct, is much to be pitied now; and as to poor Wynne himself, he protests his innocence through thick and thin. He was a wild fellow, but not the sort to take the life of a fellow-creature. I saw the doctor this afternoon while I was waiting for you at the inn, Mr. Bell, and also the police sergeant. They both say they do not know what Davidson died of. There was not the least sign of violence on the body."
"Well, I am as puzzled as the rest of you," I said. "I have one or two theories in my mind, but none of them will quite fit the situation."
The night was piercingly cold, and, although there was not a breath of wind, the keen and frosty air penetrated into the lonely signal-box. We spoke little, and both of us were doubtless absorbed by our own thoughts and speculations. As to Henderson, he looked distinctly uncomfortable, and I cannot say that my own feelings were too pleasant. Never had I been given a tougher problem to solve, and never had I been so utterly at my wits" end for a solution.
Now and then the Inspector got up and went to the telegraph instrument, which intermittently clicked away in its box. As he did so he made some casual remark and then sat down again. After the 10.40 had gone through, there followed a period of silence which seemed almost oppressive. All at once the stillness was broken by the whirr of the electric bell, which sounded so sharply in our ears that we both started. Henderson rose.
"That"s the 11.45 coming," he said, and, going over to the three long levers, he pulled two of them down with a loud clang. The next moment, with a rush and a scream, the express tore down the cutting, the carriage lights streamed past in a rapid flash, the ground trembled, a few sparks from the engine whirled up into the darkness, and the train plunged into the tunnel.
"And now," said Henderson, as he pushed back the levers, "not another train till daylight. My word, it is cold!"
It was intensely so. I piled some more wood on the fire and, turning up the collar of my heavy ulster, sat down at one end of the bench and leant my back against the wall. Henderson did likewise; we were neither of us inclined to speak. As a rule, whenever I have any night work to do, I am never troubled with sleepiness, but on this occasion I felt unaccountably drowsy. I soon perceived that Henderson was in the same condition.
"Are you sleepy?" I asked of him.
"Dead with it, sir," was his answer; "but there"s no fear, I won"t drop off."
I got up and went to the window of the box. I felt certain that if I sat still any longer I should be in a sound sleep. This would never do.
Already it was becoming a matter of torture to keep my eyes open. I began to pace up and down; I opened the door of the box and went out on the little platform.
"What"s the matter, sir?" inquired Henderson, jumping up with a start.
"I cannot keep awake," I said.
"Nor can I," he answered, "and yet I have spent nights and nights of my life in signal-boxes and never was the least bit drowsy; perhaps it"s the cold."
"Perhaps it is," I said; "but I have been out on as freezing nights before, and----"
The man did not reply; he had sat down again; his head was nodding.
I was just about to go up to him and shake him, when it suddenly occurred to me that I might as well let him have his sleep out. I soon heard him snoring, and he presently fell forward in a heap on the floor.
By dint of walking up and down, I managed to keep from dropping off myself, and in torture which I shall never be able to describe, the night wore itself away. At last, towards morning, I awoke Henderson.
"You have had a good nap," I said; "but never mind, I have been on guard and nothing has occurred."
"Good G.o.d! have I been asleep?" cried the man.
"Sound," I answered.
"Well, I never felt anything like it," he replied. "Don"t you find the air very close, sir?"
"No," I said; "it is as fresh as possible; it must be the cold."
"I"ll just go and have a look at the light at the tunnel," said the man; "it will rouse me."
He went on to the little platform, whilst I bent over the fire and began to build it up. Presently he returned with a scared look on his face. I could see by the light of the oil lamp which hung on the wall that he was trembling.
"Mr. Bell," he said, "I believe there is somebody or something down at the mouth of the tunnel now." As he spoke he clutched me by the arm. "Go and look," he said; "whoever it is, it has put out the light."
"Put out the light?" I cried. "Why, what"s the time?"
Henderson pulled out his watch.
"Thank goodness, most of the night is gone," he said; "I didn"t know it was so late, it is half-past five."
"Then the local is not due for an hour yet?" I said.
"No; but who should put out the light?" cried Henderson.
I went to the door, flung it open, and looked out. The dim outline of the tunnel was just visible looming through the darkness, but the red light was out.
"What the d.i.c.kens does it mean, sir?" gasped the Inspector. "I know the lamp had plenty of oil in it. Can there be any one standing in front of it, do you think?"
We waited and watched for a few moments, but nothing stirred.
"Come along," I said, "let us go down together and see what it is."
"I don"t believe I can do it, sir; I really don"t!"
"Nonsense," I cried. "I shall go down alone if you won"t accompany me.
Just hand me my stick, will you?"
"For G.o.d"s sake, be careful, Mr. Bell. Don"t go down, whatever you do. I expect this is what happened before, and the poor fellows went down to see what it was and died there. There"s some devilry at work, that"s my belief."
"That is as it may be," I answered shortly; "but we certainly shall not find out by stopping here. My business is to get to the bottom of this, and I am going to do it. That there is danger of some sort, I have very little doubt; but danger or not, I am going down."
