"You will go up to a small room with a chair and a bed in it, and undress." A pause, and another nod from the astonished Bilk. "You will put on a long white robe coming down to your ankles. At half- past nine the place will be dark--as black as pitch." Bilk shuddered a little at the prospect. "Then will be the time to escape your peril, or else to fall a victim. To escape it you must go quietly down the stairs and out of the house. The being who rules your life will be away for this one evening, and you will escape through his room by the window, which is close to the ground." Bilk started once more. _He_ knew the doctor was to be out that evening, but what short of supernatural vision could tell the gipsies of it? "You must escape in the long white robe, and run past here on to the cross roads. No one will see you. At the cross roads there is a post with four arms. You must climb it and sit on the arm pointing this way until the clock strikes twelve. The peril will then be past, and your fortune will be made. Not a word. Go, and beware, Alexander Magnus Bilk!" The legs of the scared Alexander could scarcely uphold him as he obeyed this last order, and sped trembling towards the school. The gipsies sat motionless as his footsteps echoed down the lane and died slowly away into silence. Then they rose to go also; but as they did so other footsteps suddenly sounded, approaching them. With an alacrity astonishing in persons of their advanced age they darted back to their place of retreat; but too late. The footsteps came on quickly, and followed them to their very hiding-place, and next moment the light of two bullseyes turned full upon them, and the aged couple were in the hands of the police. CHAPTER THIRTY FOURCHAPTER TWO. De Prudhom did not often allow himself the luxury of an evening out during term time. But on this particular evening he was pledged to fulfil a long-standing engagement with an old crony and fellow-bachelor, residing about two miles from the school. By some mysterious means the worthy dominie's intentions had oozed out, and Bilk was by no means the only boy who had heard of it. Mice seem to find out by instinct when the cat is away, and fix their own diversions accordingly. I merely mention this to explain that as far as Alexander Magnus was concerned no night could have been more favourable for carrying out the intricate series of instructions laid down by the gipsy for the making of his fortune. With this reflection he consoled himself somewhat as he ran back to the school.
