Although Tarzan was called early the following morning, the company of spahis was on the march before he had finished his breakfast. He was hurrying through his meal that the soldiers might not get too far in advance of him when he glanced through the door connecting the dining room with the bar.
To his surprise, he saw Gernois standing there in conversation with the very stranger he had seen in the coffee-house at Bouira the day previous. He could not be mistaken, for there was the same strangely familiar attitude and figure, though the man’s back was toward him.
As his eyes lingered on the two, Gernois looked up and caught the intent expression on Tarzan’s face. The stranger was talking in a low whisper at the time, but the French officer immediately interrupted him, and the two at once turned away and passed out of the range of Tarzan’s vision.
This was the first suspicious occurrence that Tarzan had ever witnessed in connection with Gernois’ actions, but he was positive that the men had left the barroom solely because Gernois had caught Tarzan’s eyes upon them; then there was the persistent impression of familiarity about the stranger to further augment the ape-man’s belief that here at length was something which would bear watching.
A moment later Tarzan entered the barroom, but the men had left, nor did he see aught of them in the street beyond, though he found a pretext to ride to various shops before he set out after the column which had now considerable start of him. He did not overtake them until he reached Sidi Aissa shortly after noon, where the soldiers had halted for an hour’s rest. Here he found Gernois with the column, but there was no sign of the stranger.
It was market day at Sidi Aissa, and the numberless caravans of camels coming in from the desert, and the crowds of bickering Arabs in the market place, filled Tarzan with a consuming desire to remain for a day that he might see more of these sons of the desert. Thus it was that the company of spahis marched on that afternoon toward Bou Saada without him. He spent the hours until dark wandering about the market in company with a youthful Arab, one Abdul, who had been recommended to him by the innkeeper as a trustworthy servant and interpreter.
Here Tarzan purchased a better mount than the one he had selected at Bouira, and, entering into conversation with the stately Arab to whom the animal had belonged, learned that the seller was Kadour ben Saden, sheik of a desert tribe far south of Djelfa. Through Abdul, Tarzan invited his new acquaintance to dine with him. As the three were making their way through the crowds of marketers, camels, donkeys, and horses that filled the market place with a confusing babel of sounds, Abdul plucked at Tarzan’s sleeve.
“Look, master, behind us,” and he turned, pointing at a figure which disappeared behind a camel as Tarzan turned. “He has been following us about all afternoon,” continued Abdul.
“I caught only a glimpse of an Arab in a dark-blue burnoose and white turban,” replied Tarzan. “Is it he you mean?”
“Yes. I suspected him because he seems a stranger here, without other business than following us, which is not the way of the Arab who is honest, and also because he keeps the lower part of his face hidden, only his eyes showing. He must be a bad man, or he would have honest business of his own to occupy his time.”
