Billy shuffled the postcards with absent hands and stared down at them with unseeing eyes.  She was gone—­and the Captain was not with her!  That much at least was gain.  And the fellow was here sick from his shot hand, apparently.  “I hope gangreen sets in,” he said between his teeth.

“You are pleased with me, sir?” the Imp was demanding.  “You are glad of so much clever boy?  And you give me that money now to give that girl?  I make her most honest promise—­and you see, sir, I am very honest boy, I tell you all I know and I ask nothing of price yet.  I know that you are honest American man.”

At that Billy came out of his brown study and praised the tattered little Imp with hearty earnestness.  He saw no reason to doubt the boy’s story.  If he had been trying to invent something in order to make capital out of him he would hardly have invented that story of Arlee’s departure, for that put an immediate end to further remunerative investigations in the palace.  Of course Billy might be mistaken, and the boy might be mistaken, but one had to leave something to probabilities.  He was very generous with the boy, and the droll little brown face was lined with grins.  Most naively he besought that the American would not reveal the extent of his donations to Mohammed, the one-eyed man, as the boys had promised their employer a just one-half.

It was the first laugh Billy had enjoyed in a long time.  His spirits were vastly lightened by the news that Arlee was out of the palace where the Captain was staying.  Fritzi had optimistically informed him that the Turk’s courtship could be made most lengthy, but that had been a sadly slender hope and the picture of Arlee playing such a fearful game was simply horrible to him.  So his relief at her departure was intense, although it complicated more and more the hope of speedy rescue.

For where was she now?  In Cairo?  In some of the outlying villages?  He felt swamped by the number of things were to be found out immediately.  He must find where that big gray motor went so early on Sunday—­surely there were people who had remarked it if they could only be found and induced to talk!  And he must find where the Captain had other homes or palaces where he would be likely to hide a girl.  And he must find out where the Captain was every instant of the day and night.

That was the most important thing of all.  For the Captain unless delayed by extreme illness, or held back by a caution which Billy judged was foreign to his nature, would not wait long before he joined Arlee.  He had evidently stayed behind for some review of his troops and also to be au courant of whatever stir would result from Fritzi Baroff’s reappearance in the world, and be on hand to disarm whatever further suspicions would result from it.  The lights in the rose room that last night and the used look of the room, puzzled Billy, but he concluded that the Captain liked the room and there was a good deal in that palace that had better be left to no imagination whatever.
