A keen zest for this extravagant adventure seized him. He thought that it must be good to be a burglar. Then, as he heard the motor re-started and the car move off, a sudden qualm of disquiet came; for it was tantamount to burning one's boats.

"Take my hand!" he heard; and was led to the head of a flight of steps. Cautiously he felt his way down, in the wake of his guide.

A key was turned in a well-oiled lock, and he was guided inside a building. There was a faint, crypt-like smell—vaguely familiar.

"Quick!" said the soft voice—"remove your boots and leave them here!"

Sheard obeyed, and holding the guiding hand tightly in his own, traversed a stone-paved corridor. Doors were unlocked and re-locked. A flight of steps was negotiated in phantom silence; for his companion's footsteps, like his own, were noiseless. Another door was unlocked.

"Now!" came the whispered words: "Remove the handkerchief!"

Rapidly enough, Sheard obeyed, and, burning with curiosity, looked about him.

"Good heavens!" he muttered.

A supernatural fear of his mysterious cicerone momentarily possessed him. For he thought that he stood in a lofty pagan temple!

High above his head a watery moonbeam filtered through a window, and spilled its light about the base of a gigantic stone pillar. Towering shapes, as of statues of gods, loomed, awesomely, in the gloom. Behind the pillar dimly he could discern a painted procession of deities upon the wall. Glancing over his shoulder, he saw that the tall figure of Séverac Bablon was at his elbow.
