"Oh, yes," laughed Mrs. Petre hoarsely; "we're just playing you a little music—to send you to sleep—to put the seal of silence upon you, Mr. Royle. And I hope you'll sleep very well to-night—very well—as no doubt you will!" and she gave vent to a loud peal of harsh laughter.

Then, for a moment she hesitated, until suddenly she cried to the Hindu:

"Enough!"

The music ceased instantly, and the snake, whose hooded head had been swaying to and fro slowly, suddenly shot up erect.

The spell of the music was broken, and I knew my doom was sealed.

Those small, brilliant eyes were fastened upon mine, staring straight at me, the head moving very slowly, while those three brutes actually watched my agony of terror, and exchanged smiles as they waited for the reptile to strike its fatal blow.

In an instant its fangs would, I knew, be in my face, and into my blood would be injected that deadly venom which must inevitably prove fatal.

Yes, I had been entrapped, and they held the honours in the game. After my death Phrida would be denounced, accused, and convicted as an assassin. Because, perhaps, I might be a witness in her favour, or even assist her to escape arrest, this woman had taken the drastic step of closing my lips for ever.

But was it with Digby's knowledge? Had he ever been her accomplice in similar deeds to this?

Suddenly I recollected with a start what Edwards had told me—that the real Sir Digby Kemsley, an invalid, had died of snake-bite in mysterious circumstances, in Peru; and that his friend, a somewhat shady Englishman named Cane, had been suspected of placing the reptile near him, owing to the shouts of terror of the doomed man being overheard by a Peruvian man-servant.
