"I don't understand," said Madame.

"Not understand? Why, a drop of the priceless liquid which this Golden Flask contains, if placed upon your tongue, would send new life coursing through your veins. It would give you power, strength, vitality greater than youth itself! You could do anything—accomplish wonders—perform miracles—if you but tasted this precious liquid!"

"How odd!" exclaimed Madame, beginning to feel bewildered. And then she asked: "Where did you get it?"

"Ah! that is the story. That is what you must know," answered Ali Dubh. "It is centuries old, the Great Elixir. There is no more of it in all the world. The contents of this flask came into the keeping of the Ancestor of the Chief of my Tribe—whom we call a Shiek—and has been handed down from father to son as an heirloom more priceless than diamonds. The Chief of my Tribe, its last owner, carried the flask always hidden in his breast. But one day, when he and I were hunting together, a mad camel trampled the Shiek to his death, and with his last breath he gave the Great Elixir into my keeping. The Shiek had no son, and the flask was really mine. But many other Arab Shieks longed for the treasure and sought to gain it. So I escaped and wandered over the world. I came here, thinking I was safe from pursuit. But they have followed me!"

"All the way from Arabia?" asked Madame.

"Yes. To-day I saw them. They know my lodgings. They are secretly hidden near, and before morning I know they plot to kill me and secure the Great Elixir. But for a time I have escaped them. I came here unseen. You must help me. You must take charge of the Great Elixir and keep it safely for me."

"Nonsense!" cried Madame, becoming aroused at last.

"Do not say that, I beg of you," exclaimed the eager Arab. "You are honest—I know you are! And they will never suspect you of having the Golden Flask."

"Perhaps not," said Madame, "and then, again, they may. My business is to tend the shop, and I am not going to get myself killed by a lot of desperate foreigners just to oblige you, Monsieur Ali Dubh! Take your Great Elixir to some one else. I don't want it."
