"You have saved my life: is there nothing I can do for you?"

"I have just told you what to do—leave?"

Probably there would have been less promptness in complying with the command had there been less in uttering it. As it was, Almos, without a word, motioned to the rest of his band, and led the way down the path in the direction of the stream, the four tramping after him like so many ragged phantoms.

Dr. Marlowe was more eager to leave the place than he would permit his child to know. He had no faith in Almos's promise, knowing that the Ghoojur chieftain would break his oath, which he and his brother fanatics did not consider binding when made to infidels, and the only hope, therefore, was for the fugitives to conceal themselves from the miscreants—a thing which the physician's intimate knowledge of the country would enable him to do.

Footfalls sounded along the path over which the two had just come, and a minute later Almos, Mustad and their three companions emerged into the opening and approached the couple, one of whom suspected nothing until her father spoke.

"Well, Almos, what do you want?" demanded Dr. Marlowe, calmly looking up at the Ghoojur chieftain, as he paused in front of him and made a salaam.

"We have come for the infidel and his daughter; our deen commands us to put them to death."

"What does the oath you gave me a little while ago command you to do?"

"That was made to an infidel; it is not binding upon a true son of the Prophet."

"A true son of the devil!" exclaimed the physician, unable to repress his rage.
