Whatever the cripple might have intended to say, the speech was never finished; for, at that moment, the electric lights vanished suddenly, plunging the whole house into absolute darkness. A moment later, footsteps came hurrying along in the hall, and a voice was heard to say that the fuse from the meter had gone, and it would be impossible to turn on the light again until the officials had been called in to repair the damage. At the same moment, Gurdon rose to his feet and crept quietly in the direction of the door. Here, at any rate, was a chance of escape, for that his life was in dire peril he had felt for some little time. He had hardly reached the doorway when he felt a slim hand touch his, and he was guided from the room into the passage beyond. He could give a pretty fair idea as to the owner of the slim fingers that trembled in his own, but he made no remark; he allowed himself to be led on till his feet stumbled against the stairs.

"This way," a voice whispered. "Say nothing, and make no protest. You will be quite safe from further harm."

Gurdon did exactly as he was told. He found himself presently at the top of a staircase, and a little later on in a room, the door of which was closed very quietly by his guide.

"I think I can guess who I have to thank for this," Gurdon murmured. "But why did you not take me to the front door, or the back entrance leading to the garden? It was lucky for me that the lights failed at the critical moment—a piece of nominal good fortune, such as usually only happens in a story. But I should feel a great deal safer if I were on the other side of the front door."

"That is quite impossible," Vera said, for it was she who had come to Gurdon's rescue. "Both doors are locked, and all the rooms on the ground floor are furnished with shutters. As to the light going out, I am responsible for it. I learned all about the electric light when I lived in a mining camp in Mexico. I had only to remove one of the lamps and apply my chisel to the two poles, and thereby put out every fuse in the house. That is why the light failed, for it occurred to me that in the confusion that followed the darkness, I should be in a position to save you. But you little realise how near you have been to death to-night. And, why, oh, why did you follow me in this way? It was very wrong of you."

"It was Venner's idea," Gurdon said. "He had a strange fear that you were going into some danger. He asked me to follow you, and I did so. As to the manner of my getting here—"

"I know all about that," Vera said hurriedly. "I have been listening to your conversation. I dare say you are curious to know something more about this strange household; but, for the present, you will be far better employed in getting away from it. I shall not be easy in my mind till you are once more in the street."

CHAPTER VIII

MISSING

Gurdon waited to hear what his companion was going to say now. He had made up his mind to place himself implicitly in her hands, and let her decide for the best. Evidently, he had found himself in a kind of lunatic asylum, where one inhabitant at least had developed a dangerous form of homicidal mania, and he had a pretty sure conclusion that Vera had saved his life. It was no time now to ask questions; that would come later on.
