The detective made sure that the men had scattered, and that the search was in full blast, when he doubled on his course and moved down toward the warehouse. Here again he displayed his reckless courage. He approached the small building on the bluff, from the rear, and entered it, and one mystery was explained—the building was but the cover to the entrance to an immense underground warehouse.
A lantern was hanging near by, and the detective seized it and descending the stairs entered a great store-house.
A sight met his gaze which filled him with amazement. His fortune was made at last; the store-house was filled with packages of valuable goods; indeed, an immense fortune lay scattered about.
Later on the detective came to learn more particularly the methods of the smugglers, but for the present as he stood there he realized that he was a wondrously lucky man, unless he should prove unlucky enough to be captured.
While standing in the subterranean store-house an idea entered his mind and he exclaimed:
"By George, that's just the scheme."
He returned to the upper room and replaced the lantern, and immediately redescended to the storehouse.
The detective had a masked lantern with him, having secured it while abiding a few hours at the home of his guide, Taylor.
Spencer Vance had determined to hide himself in the smugglers' underground warehouse. He had reached the conclusion that he could find no safer place.
Spencer Vance had struck a big scheme. Even while in such great peril, and while busy, he was revolving in his mind all the chances and contingencies; but over all loomed the possibility of discovery. There was no friendly sea to receive him should those men find him secreted in their treasure den.
