"There's a monstrous creature out there," he said evenly when a white-faced Davis demanded information. "Heaven knows how big it is, but it's something like a huge squid. It may be the kind that sperm whales feed on, down in the depths." Others from the tracking station arrived, panting. "Oh! I'm tired of being conservative!" added Terry fiercely. "I'm going to say what all of us think! There's something intelligent down at the bottom of the sea, five miles down!" He glared challengingly around him. "Who doesn't believe that?" he demanded. "Well, the reporting gadgets don't report any more. We killed the fish that carried them. So that whatever-it-is down on the sea-bed has very cleverly sent up something we ignorant savages wouldn't dare to meddle with! We would be terrified. But we'll show _it_ what men are like!" Dr. Morton said gently, "Perhaps we should notify the _Pelorus_. The biologists on board there...." "No!" said Terry grimly. "I have a private quarrel with this monster. It might have killed Deirdre! And Davis already tried to tell those biologists something! Tell them about this, and they'll want proofs they wouldn't look at anyhow. We'll handle this ourselves! It's too important for them!" "Much too important," said Deirdre firmly. "The shooting stars aren't shooting stars and there's something down in the depths just like Terry says. He's right that we can't consider sharing our world with--beings that come down from the sky, even if they only want our oceans and don't care about the land. He says that we wouldn't get along with creatures that know more than we do, and we would especially resent any space ships coming uninvited to start colonies on our world while we're not advanced enough to stop them! If that's what they're doing, they have to be fought from the very first instant to the very last moment there's one of them hiding in our seas! Terry's right!" "I haven't heard him say any of those things, young lady," said Morton drily, "but they're true. And I don't like the idea of a sea monster being in the lagoon anyhow. Especially one that tries to kill people. Still, fighting it...." "There are a couple of bazookas on the _Esperance_," said Terry sharply. He looked at Davis. "If you're willing to risk the yacht, we can drive the beast aground, or at least to shallow water, with the submarine horn. Then the bazookas should be able to destroy it. Will you take the risk?" "Of course you'll use the _Esperance_," said Davis. "Of course!" "Then I'll want," said Terry, unconsciously taking command, "somebody at the engine and somebody at the wheel. I'll run the horn. But, frankly, if that monster lays one sucker-arm on the _Esperance_, it may be good-bye. Any volunteers?"
