Dick had seen the stranger, also, and he joined Buckhart at once, saying:

“Come ahead, Brad. It’s time to find out if he’s following us round.”

Budthorne had hastened to his sister’s side.

The boys ran to the point of the wall. When they reached the spot, they could see nothing of the man.

“He can’t be far away,” said Dick.

A few moments later they discovered the man walking hastily down the hill. Unless they chose to run after him, there was no prospect of overtaking him.

“Better let him go this time,” advised Dick.

“All right,” muttered the Texan; “but he is causing me to wax wroth some, and I’ll give him a game of talk the next time I find him dogging us. Who do you reckon he is, pard?”

“I am unable to answer the question,” admitted Dick; “but, by his appearance, he seems to be a Turk.”

“That’s right. I don’t fancy being spied on by a Turk, just at present. We’re not far enough away from Damascus. He may be one of the sultan’s secret police, sent after us for that little affair in which we were recently involved.”
