"This hammer and chisel will gnaw our way out," he answered. "The game isn't up yet. Good-by. I've got to work in Davy Jones's workshop."
Drawing a deep breath, he dropped down under water, which hid him from sight like a roof of thick gray glass. Then, in a few seconds, we heard a knocking, muffled, mysterious, somewhere below that glass roof.
After a time which seemed long to every one, and an age to me, up came Alb's head, wet, black, and glittering.
"Wish I had a diver's helmet," he said, when he had breathed; and promptly dipped out of sight again.
Once more the knocking came. Alb was working hard and loyally for my interests, and against his own, I couldn't help remembering; but meanwhile we were floating idly, losing precious time, while the pirate gained upon us. Fifteen minutes more of this inaction, and he would be on our backs. I almost wished that he were a true pirate, and that it might be a war of knives and cutlasses, instead of wits and tongues. I could be brave enough then; but as a fraudulent nephew detected with his false aunt, so to speak, in his mouth, what wonder if I felt my heart turn to water?
Twice more Alb came up to breathe, and dived again. The last time all was still underneath the water, and a fear came over me that Alb had knocked his head against something, or got a cramp. But he appeared, spluttering, and announced that he had been cutting the wire through with the chisel. There it was in his hand, a thick, ugly coil, dangerous as an octopus.
"Start the motor, Hendrik," he called, even before he had clambered on deck. "Now, ladies, unless you go below you may get a shower bath, for we're going to have a race with the motor-boat that's coming along—just for the fun of the thing, you know—and I can't trust the wheel to any one while I run down and change."
"We shan't mind a wetting," said Nell, whose eyes were shining with something very like admiration. "We want to see the race."
"I would rather you saw it from the cabin windows," said Brederode; and I guessed at once that he had more than one object in hustling the women of the party below. The L.C.P. guessed also, and headed a reluctant procession.
Now the pursuing Vengeance was not five hundred yards behind, and if we had ever doubted that she was "Wilhelmina," we doubted no longer. I could distinctly see a man's figure in the bow, and would have felt safe in staking any sum that it was Sir Alec's.
