"Where are we going?"
"To be killed, sor."
Caradoc moved slowly over to the rail and sat against it near Madden.
"A cool breeze," he murmured gratefully.
The American was lost amid the wildest speculations as to the mysterious agent that had the Vulcan in tow. He was trying to think logically, but found it hard in that atmosphere of terror. The utter weirdness of the whole affair defied analysis. The towing of the Vulcan by an unknown power was the very climax of the fantastic. No hypothesis he could form even remotely approached an explanation.
It could not be some sea monster surging steadily at the tow line of the Vulcan. That theory was untenable. A monster might attack; it would never tow.
But any other, attempt to account for the strange predicament fell equally as flat. What human agency would operate so mysteriously in this hot, stagnant sea? Why should any group of men entrap the helpless crew of the Vulcan with such a display of mystery and power? It was useless. It was ridiculous. It was shooting a mosquito with a field gun.
All his thoughts ended in utter absurdity. He felt that he had run up against some vast power. The schooner Minnie B, the tug Vulcan, were but trifling units in the enigma of this deserted, weed-clogged sea. It must be some power whose operations were ocean-wide.
Why such a spot should be chosen?—Why a power that sank one ship out of hand and towed another mile after mile?—Why it operated only at night?—What lay at the heart of this brooding fabric of terror—he could not form the slightest conception. Outlawry, piracy, smugglery, were all goals too small for such operations.
His thoughts seemed to be physical things trying to clamber up the smooth polished side of an enormous steel plate. They made not the slightest progress. The more he thought, the more unaccountable all phases of the question became.
