"The wall's down!" John Dark yelled, his atom-gun leaping into his hand. "Get back into the ship—get back—"

The crash of his atom-gun drowned his own shout. Other pirates were firing wildly at the hideous creatures assailing them.

For the little gray Vestans had detached themselves from their animal victims and were swarming upon the pirates, clambering with blurring speed up their legs and backs, sinking into their necks the tiny antennae.

Kenniston glimpsed John Dark, with a hideous little gray bunch now fastened to the back of his neck, drop his gun and stalk stiffly away toward the jungle. His face was an unhuman, lifeless mask—he was a human automaton, dominated utterly by the alien creature.

"Come on!" Kenniston yelled to his friends. "Now's our chance to get into the ship!"


hey plunged out of the hut into the gruesome melee. Screaming pirates were now running into the jungle in vain effort to escape the hordes of Vestans. More than half the corsairs were now overcome.

Kenniston heard a scream from Gloria as they ran, felt a swift scurrying up his back, then the needle-like stab of antennae sinking into his neck.

But the parasitic creature did not overpower his will! He reached around, grasped and tore loose the hideous little thing, and with strong revulsion flung it to the ground.
