In this fairyland which had enjoyed centuries of peace, health and accord, stark terror now reigned. In some instances the finely-bred, marvellously intelligent people were in a mental condition bordering on madness.

This was especially true in the farming districts, where whole herds of lats had been wiped out. Lats, Larner gleaned, were a common farm animal similar to the bovine species on earth, only more wooly. On these creatures the Venus dwellers depended for their milk and dairy supplies, and for their warmer clothing, which was made from the skin. The hair was used for brushes, in the building trades, and a thousand ways in manufacturing.

Besides the domestic animals hundreds of people continued to meet death, and only a few of the flying vampires had been hunted down. The giant insects were believed to breed slowly as compared to earth insects, their females producing not more than ten eggs, by estimate, after which death overtook the adult. In spite of this they were reported to be increasing.

In the Government building Larner was placed in touch with all the Government scientists of Venus. His nearest collaborator was one Zorn Zada, most profound scientist of the planet. The two men, with a score of assistants, worked elbow to elbow on the most gigantic scientific mystery in the history of two planets.

A specimen of the dread invader was mounted and studied by the scientists, who were so engrossed in their work that they hardly took time to eat. As for sleep, there was little of it. Days were spent in research and nights in hunting the monsters. This hunting was done by newly recruited soldiers and scientists. The weapons used were a short ray-gun of high destructive power which disintegrated the bodies of the enemies by atomic energy blasts. The quarry was wary, however, and struck at isolated individuals rather than massed fighting lines.


Seated at his work-bench Larner asked Zorn Zada what had become of Nern Bela. In his heart he had a horrible lurking fear that the beautiful Tula Bela might fall before a swarm of the strange vampires, but he did not voice this anxiety.

"Nern and his sister are explorers and navigators," was the reply. "They have been assigned to carry you anywhere on this or any other planet where your work may engage you. They await your orders. They are too valuable as space-navigators to be placed in harm's way."

Breathing a sigh of relief, Larner bent to his labors.
