Four unwavering rifles were bearing upon the surprised islanders and four very material men were advancing from the ghostly darkness. An electric lantern shot a ray of light athwart the scene.

"Drop your guns—quick!" commanded Chase. "Don't make a row!"

Paralysed with fear and amazement, the men obeyed. They could not have done otherwise. The odds were against them; they were bewildered; they knew not how to combat what seemed to them an absolutely supernatural force.

While the three white men kept them covered with their rifles, Selim ran to the gate, uttering the shrill cry of a night bird. There was a rush of feet inside the walls, subdued exclamations, and then a glad cry.

"Quick!" called Selim. The keys rattled in the locks, the bolts were thrown down, and an instant later, Lady Deppingham was flying across the space which intervened between her and the gate, where five or six figures were huddled and calling out eagerly for haste.

The men were beside her a moment later, possessed of the weapons of the helpless sentinels. With a crash the gates were closed and a joyous laugh rang out from the exultant throat of Hollingsworth Chase.

"By the Lord Harry, this is worth while!" he shouted. Outside, the maddened guards were sounding the tardy alarm. Chase called out to them and told them where they could find the four men in the forest. Then he turned to follow the group that had scurried off toward the château. The first grey shade of day was coming into the night.

He saw Neenah ahead of him, standing still in the centre of the gravelled path. Beyond her was the tall figure of a man.

"You are a trump, Neenah," cried Chase, hurrying up to her. "A Persian angel!"

It was not Neenah's laugh that replied. Chase gasped in amazement and then uttered a cry of joy.
