A sudden light came into Cleek's eyes, a sudden smile curved the corners of his mouth at this proof of Ailsa's trust in him, and he led the way out of the station.

Outside, Dollops was speedily dismissed to get a long-wished-for meal. Realizing that his beloved master was happy in his self-appointed task, he relinquished his place at the wheel, and was speedily lost to sight in the ever-moving kaleidoscope of the Strand.

Meanwhile, Ailsa, having snugly tucked in her travelling companion on the seat of the limousine, and seen that she was half asleep, betook herself to the front seat beside Cleek. And they started on the road which was to carry him once more nearer crime and disaster than any man would care to go.

"That poor child!" she said, when the car was humming softly along, and whisking them out of London. "I watched her have such a pitiful parting with the nuns at Calais, and afterward, when she was so ill and lonely on board. I tried to cheer her up. It seems that she has been at Notre Dame Convent in Paris all her life, except for one stray holiday with a friend, and now she comes of age next week, and has got to live with a sour old aunt, an eccentric being who I think must be jealous of the child's youth and beauty. She will be shut up in Cheyne Court. It's a dreadful spot, too. I know it well. I have often passed it. I don't wonder she is dreading it. All the jewels in the world are not worth imprisonment in such a dreary dungeon as Cheyne Court must be!"

Cleek twitched up an enquiring eyebrow.

"Jewels?" he questioned, musingly. "Hm! Wait one moment. Lady Margaret Cheyne did you say? Let me see. I don't profess to be a walking Debrett, but I fancy the name recalls some strange memory. Lord Cheyne now—didn't he marry Miss Peggy Wynne, known over London as 'the beautiful Irish girl'? Yes, and she died, too, at the child's birth I remember. Hm! a heavy inheritance that, a thousand pities she wasn't a boy—— What's that, dear? Why? Why, the title dies out with her, and she comes into all the family jewels. I don't wonder you think one can pay too high a price for jewels, priceless though they be, for if my memory serves me rightly, these include that ill-fated stone, the Purple Emperor——" His voice trailed into silence, he sat a moment staring ahead, and Ailsa forbore to question him.

Then he threw back his shoulders as if thrusting away the sorrow of the world, and with a tilt of the head, turned again to Ailsa.

"Ah, well, it's so far back that perhaps the fates will be kind," he said, musingly. "Perhaps you'd like to hear something of the story. We'll drive slower then. 'The Purple Emperor,' or to give its right name, the 'Eye of Shiva,' is, as you can guess, an Indian stone, and was looted from a temple at Benares in the days of the ill-fated Indian Mutiny. It was brought to England by a member of the Cheyne family—'Mad Cheyne' I think they called him—and there is a special police chronicle of the crimes committed by, and at the instigation of, the priests of the temple in their efforts to get it back into their possession again. I expect they have given it up now, for last thing I heard of that historic stone was that it was embedded in a concrete safe in the Bank of England."

Ailsa's face had become very pale while he was speaking, and as he paused she gave a little shiver.
