Together the two men left the temple. Once more Chenobi touched the spring in the masonry; then, as the door swung open, a savage cry burst from his lips. The chamber was empty—Nordhu had vanished!

[CHAPTER XXXI.]

“THE SEAL!”

THE way of the priest’s escape became clear at once. In the rear wall of the chamber a small door stood ajar.

“I thought not that he knew of the passage,” the Ayuti hissed; “but he shall not escape. Take you the hounds, Fairhair, and follow. I know whereto this passage leads, and will ride round upon Muswani to cut him off.”

Within five minutes the pursuit was in full swing. The hounds were loping down the passage on the trail of Nordhu, with the explorers close behind, while the king was galloping away from the city on his elk, hoping to intercept the flying priest.

“Say,” exclaimed Haverly, “I guess this temple must be kinder honeycombed with passages.”

“It’s a wonderful building,” returned Mervyn. “These passages are doubtless arranged for the convenience of the priests——”

“Nordhu must have the devil’s own cunning to have found that secret door,” interrupted Seymour savagely; “But he won’t escape for all his wiles. If the hounds get hold of him he’ll have short shrift.”

Down a flight of stairs the pursuers went, the great hounds making the passage ring with their baying; then on once more, the tunnel twisting and winding in such a fashion that neither of the friends had the least idea of the direction in which they were moving. Little they cared, however, so that they might again lay hands on the fugitive priest, who, should he succeed in effecting his escape, would assuredly once again attempt their destruction. His capture was a necessity if they would ever find their missing comrade and the vessel; for, with Nordhu at liberty, plotting their ruin, they would not dare venture forth to search for the Seal. So they put forth every effort in the chase, hoping at each bend of the passage they turned to come in sight of their quarry.
