"Look here," he said hoarsely. "This is witchcraft. Somebody grasped my arm, some unseen force clutched me. I managed to get away by sheer strength, but look here."

There was a ring of blood all round Denvers' wrist, the flesh had been cut almost to the bone. It seemed almost impossible for a human hand to grasp like that, but there it was. And up in the dome now there was nothing to be seen but the tangled masses of glorious blooms.

CHAPTER VIII.

THE WEAKER VESSEL.

Like most men of his class, Frobisher had a perfect knowledge of the art of using others. To study their weakness was always the first stage of the game, and therefore in an early stage of their acquaintance the little baronet learnt the fact that Paul Lopez was criminally extravagant with his money. How Lopez got rid of it Frobisher neither knew nor cared, the weakness paid him, and there was an end of it.

Therefore Frobisher paid his henchman liberally. There was no generosity about it, nothing but policy. That was the secret of Lopez's life, and beyond that Frobisher never attempted to penetrate. Perhaps he knew that Lopez must not be pushed too far.

Paul Lopez had contented himself with the result of his labours for the day. He was a plain, simply-dressed man himself, and gave no suggestion of a liking for the luxuries and good things of this life. All the same, he was seated now at a most perfectly-appointed table, clad in most immaculate evening-dress, and looking across a table in the centre of which was a veritable bank of flowers. Two opal electric swans floated upon what was meant to resemble a miniature lake, and these gave the only light to the dinner-table.

The dining-room was small but exquisitely furnished, for Lopez had a pretty taste that way. There were no servants in the room now, for coffee had been served, and Lopez was leaning back with the air of one who has dined wisely and well.

On the other side of the table a girl sat. She was slight and fair, with a pretty, petulant face, the spoilt look not in the least detracting from her Greuze-like beauty. Her eyes were the eyes of a woman, and her expression that of a child. Lopez called her simply Cara—not even his most intimate acquaintances knew her other name—and she was popularly supposed to be the child of some dead and gone friend. No daughter had ever had more care and love bestowed upon her than Cara, she was the one soft spot in Lopez's life. Perhaps she cared for him in a way; perhaps she had come to regard him and all these luxuries as a matter of course; certain it was that Cara lacked nothing many times when Lopez had to go without.

There was a queer, half-ashamed look on his face now, as he pulled at his cigarette. Cara had been scolding him, and he looked like a detected schoolboy.
