"Yes," said Scarmelli, in reply. "That is his name. Why?"

"Nothing, but that it solves the riddle, and the lion has smiled for the last time! No, don't ask me any questions; there isn't time to explain. Get me as quickly as you can to the place where we left Mr. Narkom's motor. Will this way lead me out? Thanks! Get back to the others, and look for me again in two hours' time; and Scarmelli?"

"Yes, sir?"

"One last word: don't let that boy get out of your sight for one instant, and don't, no matter at what cost, let the chevalier do his turn to-night before I get back. Good-bye for a time. I'm off."

Then he moved like a fleetly passing shadow round the angle of the building, and two minutes later was with Narkom in the red limousine.

"To the German embassy as fast as we can fly," he said as he scrambled in. "I've something to tell you about that lion's smile, Mr. Narkom, and I'll tell it while we're on the wing."

It was nine o'clock and after. The great show at Olympia was at its height; the packed house was roaring with delight over the daring equestrianship of "Mademoiselle Marie de Zanoni," and the sound of the cheers rolled in to the huge dressing-tent, where the artists awaited their several turns, and the chevalier, in spangled trunks and tights, all ready for his call, sat hugging his child and shivering like a man with the ague.

"Come, come, buck up, man, and don't funk it like this," said Señor Sperati, who had graciously consented to

assist him with his dressing because of the injury to his hand. "The idea of you losing your nerve, you of all men, and because of a little affair like that. You know very well that Nero is as safe as a kitten to-night, that he never has two smiling turns in the same week, much less the same day. Your act's the next on the programme. Buck up and go at it like a man."
