"We should always have Selim to examine," I remarked.

"If Laleli Khanum dies, Selim will disappear the same hour,—laying hands on everything within reach, of course. How could we catch him? He would cross the Bosphorus, put on a disguise of some sort, and make his way to Egypt in no time. Those fellows are very cunning."

"Then you mean to try and extort a confession from Laleli herself? How in the world do you mean to do it? It is a case of life or death."

"I have got life and death in my pocket," answered Gregorios, his eyes beginning to sparkle. "Can you read Turkish? Of course you can. Read that."

I took the folded document and examined it.

"This is an Iradè!" I exclaimed, in great surprise; "an imperial order to arrest Laleli Khanum Effendi,—good heavens! Balsamides, I had no idea that you possessed such tools as this!"

"To tell you how I got it would be to tell you my own history during the last ten years," he answered, in low tones. "I trust you, Griggs, but there are other reasons why I cannot tell you all that. You see the result, at all events, and a result very dearly paid for," he added gravely. "But I have got the thing, and what is more, I have permission to personate the Sultan's private physician."

"What is that for? I should think the Iradè were quite enough."

"Laleli might die of fright, if I merely presented myself and threatened to arrest her. But I shall see her in the assumed character of the court physician. Laleli is a Turkish woman, who understands no other language but her own and Greek. She is very superstitious, and believes in all manner of charms and spells; for she has no ideas at all concerning Western science, except that it is all contrary to the Koran. I can talk the jargon of an old Hadji well enough, and besides I know something of medicine; very little, but enough to tell me whether she is absolutely in a dying state. It is a great compliment for the Sultan to send his private physician, and if she is in a conscious state she will be flattered and thrown off her guard. If I can manage to get her slaves out of the way, I may induce her to confess. If I fail in this, I have the means to frighten her. If she dies, I have the means of arresting Selim before he can escape. It is all very well arranged, and there is nothing to be done but to put the plan into execution. When you left me I had not got the Iradè; it came about an hour ago."

"How can I help you?" I asked.
