With a shrug he backed into the passageway. "I cannot fight an army single-handed," he muttered. Slowly he crossed the outer court, passed through the first great wall and stood again upon the plain outside the city. In the distance he saw the dust of the fleeing expedition and, with a grin, he started in pursuit, swinging along at an easy walk as he puffed upon a cigarette. From the top of the rocky hill at his left a little monkey saw him pass—a little monkey, which still trembled from fright, but whose terrified screams had become only low, pitiful moans. It had been a hard day for little Nkima.

So rapid had been the retreat of the expedition that Zveri, with Dorsky and Ivitch, did not overtake the main party until the greater part of it was already descending the barrier cliffs; nor could any threats or promises stay the retreat, which ended only when camp was reached.

Immediately Zveri called Abu Batn, together with Dorsky and Ivitch, into council. The affair had been Zveri's first reverse, and it was a serious one inasmuch as he had relied heavily upon the inexhaustible store of gold to be found in the treasure vaults of Opar. First, he berated Abu Batn, Kitembo, their ancestors and all their followers for cowardice; but all that he accomplished was to arouse the anger and resentment of these two.

"We came with you to fight the white men, not demons and ghosts," said Kitembo. "I am not afraid. I would go into the city, but my men will not accompany me and I cannot fight the enemy alone."

"Nor I," said Abu Batn, a sullen scowl still further darkening his swart countenance.

"I know," sneered Zveri, "you are both brave men, but you are much better runners than you are fighters. Look at us. We were not afraid. We went in and we were not harmed."

"Where is Comrade Romero?" demanded Abu Batn.

"Well, perhaps, he is lost," admitted Zveri. "What do you expect? To win a battle without losing a man?"

"There was no battle," said Kitembo, "and the man who went farthest into the accursed city did not return."

Dorsky looked up suddenly. "There he is now!" he exclaimed, and as all eyes turned up the trail toward Opar, they saw Miguel Romero strolling jauntily into camp.
