"Time was running out. Sadler knew that the discovery of heavy metals on the Moon could lead to a devastating war between Earth and the younger colonies of Mars and Venus. And someone in the quiet, respectable group of scientists on the Moon -- someone Sadler had to find -- was passing information to the unseen warships in outer space. . .
If war came, the Moon would be the target. But Sadler's job was to prevent that war if he could . . . while the uneasy days, hours, seconds ticked away."
