They followed a winding course around the root structures of the trees. Lucifer tripped once and fell sprawling into the wet, leathery leaves. As he got up, the spider loop of a vine caught him around the throat and flipped him again.

"Pick up your feet and keep your head down," Fetzer warned impatiently.

Their direction took them to a shallow stream, and they splashed up the middle of it for a hundred yards. The cacophony of night sounds retreated before them, closed in behind them. The rooftop of intermeshed branches and leaves dripped endlessly. Some alien creature followed them through the branches, yapping in a strident monotone.

They emerged from the stream to crawl into a semi-cave formed by the enjoining roots of two great trees. Vegetation had webbed over the roots until even the dropping of water was cut off.

The light of a guttering torch showed several men waiting for them. A few carried strange weapons stolen from Huth's men. Others were armed with vicious looking clubs, and long, needle-pointed stakes.

It's fantastic, thought Lucifer. Cavemen prepared to challenge a mechanized force. Cavemen forty light years from home.

When they saw Nina, the men stood up, surprised, uneasy. Fetzer went into some detail on what Lucifer had told him. One of the men swore, and smashed the head of his club on the sodden floor of the cave.

A balding man seated Nina on a hummock in one corner of the cave. Ignoring Lucifer, they plunged into discussion of their plans. None could see any reason for further delay. The supply ship had been gone for some time, and might return soon. Its crew would add strength to Huth's base force, which numbered around eight hundred, including nurses, doctors and various technical personnel.

To Lucifer, the plan sounded bold. Pathetically bold. A sizeable group would break out of their quarters and flee into the forest, drawing a portion of Huth's men in pursuit. Another group would attack Center, making it appear that this was the chief point of concentration. After delaying as long as possible, the main force would hit the landing field and try to capture the auxiliary spaceship. The men knew they couldn't handle the ship, but their work around the field had taught them enough about it to know that its armament could give them control of the base.

As Lucifer listened, a sense of familiarity kept tugging at him. It was a strange sensation that he had been through something like this before. But that was ridiculous. He'd never been any closer to military action than rejection by his draftboard, which had stupidly considered parapsychology non-essential.
