Trembling, sick at heart, the commander yet had to think of his men. "For God's sake," he cautioned them, "keep back. Don't try to fight now; we've got to wait our chance! Steady. Steady...."

The king's deliberate tentacle again began its slow weaving. It was choosing another victim. And this time it darted straight out at Keith Wells and gripped him with a mighty clutch about the waist.

The commander did not cry out. As he was brought close to the staring eyes, and felt their sinister gaze run over him, it flashed through him for some obscure reason that the monster knew him for what he was, the leader, from the tiny bars on each shoulder of his sea-suit.... He waited for the tentacles to rip it open.

But they did not. Instead, the creature turned and swiftly swam with him out through the entrance hole.

Perhaps the race of octopi was growing, reaching out; needed new room to colonize. That would explain why their submarine had been sent through the tunnel....

A voice sounded in his ears:
