"Put out your lights, go back to the end of the road, and wait for me," I said.

Then I hurried forward to ascertain what I could.

The taxi, having put down its two fares and been dismissed, turned and passed me as I went forward. At last I had run the sly old fox, Gregory, to earth, and I now meant to keep in touch with him.

On approaching the house I found it to be a good-sized one, standing back, lonely and deserted, in a weedy garden, and surrounded by big, high elms. From the neglect apparent everywhere, the decayed oak fence, and the grass-grown path leading to the front door, it was plain that the place was unoccupied, though in two windows lights now shone, behind dark-green holland blinds.

The place seemed situated in the centre of some market-gardens, without any other house in the near vicinity. A dismal, old-fashioned dwelling far removed from the bustle of London life, and yet within hearing of it, for, as I stood, I could see the night-glare of the metropolis shining in the sky, upon my right, and could hear the roar of motor-buses upon the main road through Spring Grove.

For a few moments I stood up under the shadow of a big bush which overhung the road, my eyes upon the lower window where the fights showed. The house was half-covered with ivy and had bay-windows upon each side of the front door, which was approached by a short flight of moss-grown steps.

That I was not mistaken in my surmise that the house was uninhabited was proved by the "To Let" notice-board which I discerned lying behind the fence, thrown down purposely, perhaps.

Was old Gregory an intruder there? Had he purposely thrown down that board in order that any person, seeing lights in the window, would not have their suspicions sufficiently aroused to cause them to investigate?

The house was a dark, weird one. But what would I not have given to be inside, and to overhear what was being planned!

Vernon Gregory was, according to Lola, the instigator of all those marvellously ingenious thefts effected by Jeanjean. Was another great robbery being planned?
