"Do you mean that you are going down again to the tunnel?" he gasped.
"Yes," I said; "give me those matches. You had better come too. I don't think there will be much danger now; and there is daylight, so we can see what we are about."
The man was very loth to obey me, but at last I managed to persuade him. We went down the line, walking slowly, and at this moment we both felt our courage revived by a broad and cheerful ray of sunshine.
"We must advance cautiously," I said, "and be ready to run back at a moment's notice."
"God knows, sir, I think we are running a great risk," panted poor Henderson; "and if that devil or whatever else it is should happen to be about—why, daylight or no daylight——"
"Nonsense! man," I interrupted; "if we are careful, no harm will happen to us now. Ah! and here we are!" We had reached the spot where I had fallen. "Just give me a match, Henderson."
He did so, and I immediately lit the lamp. Opening the glass of the lamp, I held it close to the ground and passed it to and fro. Suddenly the flame went out.
"Don't you understand now?" I said, looking up at the Inspector.
"No, I don't, sir," he replied with a bewildered expression.
Suddenly, before I could make an explanation, we both heard shouts from the top of the cutting, and looking up I saw Bainbridge hurrying down the path. He had come in the dog-cart to fetch us.
