"It was said to have been the plague," said Selim bitterly. "They died in great convulsions while spending the night in the Khan. That's the inn of Aratat, excellencies. The great sahibs sent their stomachs away to be examined—"

"Never mind, Selim," said Chase. "Tell us about the passage there."

"Once there was a boat—a launch, which lay hidden below the cliffs on the north coast. The passage led to this boat. It was always ready to put out to sea. But one night it was destroyed by the great rocks which fell from the cliffs in an earthquake. When I came here, I at once thought of the passage. You will see that the doors into the cellar cannot be opened from this chamber; the locks and bolts are on the other side. I knew where the keys were hidden. It was easy to unlock the doors and come into this room. I found that some one had been here before me. The door to the passage had been forced open from without—cracked by dynamite. Many of the treasure boxes have been removed. Von Blitz was here not an hour ago. He wears boots. I saw the footprints among the naked ones in the passage. They will come back for the other chests. Then they will blow up the passage way with powder and escape from the château through it will be cut off. I have found the kegs of powder in the passage and have destroyed the fuses. It will be of no avail, sahib. They will blow it up at the other end, which will be just the same."

"There's no time to be lost," cried Chase. "We must bring enough men down here to capture them when they return—shoot 'em if necessary. Come on! We can surprise them if we hurry."

They were starting across the chamber toward the door, when a gruff, sepulchral oath came rolling up to the chamber through the secret passage. Quick as a flash Selim, who realised that they could not reach and open the door leading to the stairs, turned in among the huge wine casks, first blinding his lantern. He whispered for the others to follow. In a moment they were squeezing themselves through the narrow spaces between the dark, strong-smelling casks, back into a darkness so opaque that it seemed lifeless. Selim halted them in a recess near the wall and there they huddled, breathlessly awaiting the approach of the invaders.

"They won't suspect that we are here," whispered Selim as the door to the passage creaked. "Keep quiet! Don't breathe!"

The single electric light was still burning, as Selim had found it when he first came. The door swung open slowly, heavily, and Jacob von Blitz, half naked, mud-covered, reeking with perspiration, and panting savagely, stepped into the light. Behind him came a man with a lantern, and behind him two others.

They were white men, all. Von Blitz turned suddenly and cursed the man with the lantern. The fellow was ready to drop with exhaustion. Evidently it had been no easy task to remove the chests.
