bling that we'll find the opening," Campbell told him. "Go
ahead."

Sturt's face set stolidly and he said, "Yes, sir."

He turned the prow of the cutter toward the cliffs. Instantly they
dashed forward toward the rock walls with greatly increased speed, wild
waves bearing them onward like charging stallions of the sea.

Hunched beside the helmsman, the searchlight stabbing the dark wildly as
the cutter was flung forward by the waves, Ennis and the inspector
watched as the cliffs loomed closer ahead. The brilliant white beam
struck across the rushing, mountainous waves and showed only the
towering barriers of rock, battered and smitten by the raving waters
that frothed white. They could hear the booming thunder of the raging
ocean striking the rock.

Like a projectile hurled by a giant hand, the cutter fairly flew now
toward the cliffs. They now could see even the little streams that ran
off the rough rock wall as each giant wave broke against it. They were
almost upon it.

Sturt's face was deathly. "I don't see any opening!" he yelled. "And
we're going to hit in a moment!"

"To your left!" screamed Inspector Campbell over the booming thunder.
"There's an arched opening there."

Now Ennis saw it also, a huge arch-like opening in the cliff that had
been concealed by an angle of the wall. Sturt tried frantically to head
the cutter toward it, but the wheel was useless as the great waves bore
the craft along. Ennis saw they would strike a little to the side of the
opening. The cliff loomed ahead, and he closed his eyes to the impact.

There was no impact. And as he heard a hoarse cry from Inspector
Campbell, he opened his eyes.

The cutter was flying in through the mighty opening, snatched into it by
powerful currents. They were whirled irresistibly forward under the huge
rock arch, which loomed forty feet over their heads. Before them
stretched a winding water-tunnel inside the cliff.

And now they were out of the wild uproar of the storming waters outside,
and in an almost stupefying silence. Smoothly, resistlessly, the current
bore them on in the tunnel, whose winding turns ahead were lit up by
their searchlight.

"God, that was close!" exclaimed Inspector Campbell.

His eyes flashed. "Ennis, I believe that we have found the
gathering-place of the Brotherhood. That boat we sighted is somewhere
ahead in here, and so must be Chandra Dass, and your wife."

Ennis' hand tightened on his gun-butt. "If that's so-
