"Affairs outside have changed somewhat," he continued. "The people are sullen and restless. They mistrust the Emir, and fear they will be cheated of the pleasure they are looking forward to."
Guy turned pale. "Then we are lost!" he cried.
"No, you are saved," said Canaris. "That very fact works for your salvation. The Emir is alarmed; he fears for himself, not for you. His troops are few since he despatched the caravan to Zaila, and at night, for better security, he takes guards from the prison courtyard and stations them before the palace. This leaves three guards to contend with; one watches in the corridor, one stands before the prison door, and the third guards the gateway that opens from the prison yard on to a dark avenue of the town. If all goes well you will be free men at midnight. I must hurry away now. Listen well to my instructions, and do just as I tell you.
"You," and he turned to Melton, "must pretend that your wound is bad. Refuse to eat and lie on the straw all the time. It will be better if I do not return today. I fear that even now Rao Khan grows suspicious. The Arab doctor is angered because I have assumed his duties. At midnight, if you listen sharply, you will hear the guard relieved by a new man. Soon after that knock on the door, and when the guard looks in show him the wounded man, who will then feign to be very bad. I sleep in a rear apartment of the palace. The guard will send for me, and I will come. Otherwise my visiting you at that time of night would be looked upon with suspicion. The rest I will tell you then. Don't despair. All will be well; till midnight, farewell."
Canaris glided from the dungeon, and the prisoners were alone. They passed the long hours of that day in a strange mixture of hope and fear. The difficulties to be overcome seemed insurmountable. They must escape from the prison, pass through the very midst of their bloodthirsty enemies, scale the wall, and then—where were they? Hundreds of miles from the coast, surrounded by barbarous and savage people, and their only hope that mysterious underground river which in itself was a thing to be feared.
But, on the other hand, speedy death awaited them in the dungeon of Rao Khan. The chances were truly worth taking.
They followed instructions closely when the guard brought them food at noon, and in the evening Melton tossed on the floor as though in pain. The thrice-welcomed darkness came at last, and the light faded out of their dungeon. Once a horrible thought entered Guy's mind. What was to prevent the Greek from making his escape alone, and abandoning the Englishmen to their fate? It was but momentary, however, and then he dismissed the suspicion with a feeling of shame. He had already learned to trust the Greek implicitly.
Crouched by their dungeon door, they listened by the hour, and at last their patience was rewarded. Voices were heard, steps approached and died away, and then all was silent.
The time for action had come.
Melton threw himself on the straw and moaned. Guy rapped sharply on the door and waited in suspense. Almost instantly it opened, and the guard, a tall Nubian, pushed his lamp into the doorway and followed it up with head and shoulders.
