“Why, a young man who has just accepted an invitation to a surprise party,” laughed Camberly. “We’re the hosts.”


CHAPTER XVIII.
“SAFE AS IN A STEEL-LINED VAULT.”

Whatever the future may hold in store for them, it is doubtful if either Ned or Channing Lockyer will ever forget the moment that they met on that sandy beach, surrounded in the darkness by wicked and desperate men. The surprise, however, was all on the side of the inventor. His first impulse, as his eyes fell on the bound form and he recognized it, was to give a shout of joy. His next, however, was one of regret that another should have been dragged in to share his predicament. He had no idea, of course, how the Dreadnought Boy came to be there, nor had he an opportunity to inquire.

Before a word could be exchanged between these two so strangely met, they were hustled into a small flat-bottomed boat lying on the shore, and rapidly sculled off to a long, low-lying black motor-boat which lay at anchor a short distance off shore. Once on board, the tender was at once taken in tow, the anchor hauled up, and, rapidly as a water snake, the gasoline-driven craft glided off into the darkness. Whither they were bound Ned had not the slightest idea. Only one thing was in his mind. That was a feeling of gladness that he was at least near to Channing Lockyer, and that helpless as he was at the moment, he might yet be able to render him some service, for Ned was not a lad whose spirits were easily downed. Otherwise, bound and helpless as he was, and in the hands of men whom he knew had every reason to hate him, he would have had good cause for apprehension.

How long it was before the motor craft stopped, Ned had no idea, but he knew by the lessening vibration of her engines that she was coming to a stop. Presently he heard her fenders scrape as she was run alongside a wharf. Then he was lifted up once more and carried swiftly along a small landing place and hustled off into the darkness. That they were crossing sand, he knew by the noiseless progress of the two who were conveying him.

All at once the dark outlines of a building of some sort loomed up in front of him. But before he had time to take his bearings or get the least idea of where he was, Gradbarr, who had hold of his feet, dropped them and ran swiftly forward. Ned heard the sound of a door of some kind being slammed open.

Then Gradbarr came back and picked up his feet once more.

“Now then, in with him,” he heard Camberly say, and before he had time to utter a cry, for, of course, it was impossible for him to move, Ned felt himself being held above a black pit—as it looked. The next instant he was dropped, into what abyss he knew not. A cry rang from his lips, but was stifled the next instant as he felt himself plunging down upon a floor, which, to his astonishment, was soft and yielding.
