He has not the slightest desire to do anything that will bring about a change in the plan. So long as Lady Ruth is rescued from her unpleasant position, it matters little what the means are.

Hence, he watches the development of matters with a keen interest. It is not long before he is in a position to see that there is solid truth in his suspicions. The actions of Sir Lionel confirm the fact that he has been induced to compromise his honor in order to succeed with John as a rival.

When the divine spark touches the heart, it causes men to do strange things.

Here is one who in times past has been very jealous of his honor, and would as soon cut off his hand as compromise himself. Yet, reduced to sore straits by the success of a rival, he now descends the scale, and schemes as cleverly as any rascally adventurer.

The critical period draws near, and our military hero can scarce restrain his valor. Indeed, he shows symptoms of wanting to rush out and annihilate the whole band of Arabs and Moors, but Lady Ruth restrains him, as though she is clever enough to see the folly of a move too premature.

It is a picturesque scene, and one that John will never forget. The grotto alone has charming features, since the walls are white and incrusted with some metallic substance that shines like silver.

On either side can be seen giant stalactites dependant from the roof, looking like mighty columns to support the dome.

The fire and the torches illumine the scene, until it looks like one of enchantment. The strange costumes of the nomads, with the various colors they boast, add to the romantic nature of the exposition, and his must be a poor soul, indeed, that fails to catch something of artistic fervor when such a picture appears in view.

There were twenty of Bab Azoun's men present an hour before, but now only half of that number can be seen.

The remainder have mysteriously disappeared. Things seem to be working to suit the desperate plans of the veteran Zulu fighter, and he will soon be in a condition to open the engagement.
