“I thought of that myself. I’m not anxious to be arrested and carried back to Damascus.”

“I should say not! That would be mighty bad business. Still, I don’t think——”

Dick checked his companion with an exclamation. Another man had joined the one who was rapidly descending the hill. Both boys obtained a glimpse of this second person before both disappeared into the shadows below.

“Did you see him, Brad?” asked Dick. “Did you get a fair view of him?”

“Just a look, partner, but I swear there was something a heap familiar about him. The way he carried his head—his walk—— I’ve seen that galoot before.”

“And so have I. Shall we attempt to overtake them? I’d give something to get a look at his face.”

But they decided it was too late, as there was little chance of overtaking those men in the narrow and gloomy streets of Cairo. Besides, in order to pursue the mysterious ones, they would be compelled to abandon Nadia and her brother.

So they returned and found Dunbar and Nadia waiting, and a trifle nervous.

“It’s all right,” declared Dick diplomatically. “Of course, the man had a right to come up here and view the sunset. He’s gone.”

“I’m glad,” said the girl. “But it is growing dark. Let’s return to the hotel right away. I do not fancy being out in the streets of Cairo after dark.”
