The Negative Ones

Henderson was a brilliant nuclear physicist until the night he staggered home a pathetic wreck of his former self, raving wildly about flying saucers and a strange being named Ravan. No scientific nation could afford to lose a genius of Henderson's capacity and Parnell Scott, an experimental psychiatrist, was given the job of restoring Henderson's sanity. Scott gradually infiltrated Henderson's apparent fantasy and found himself involved in research that produced frightening results.

According to ancient legends there had once lived a strange, tyrannical ruler named Ravan, who had possessed a vimana or 'flying car'. Bur Henderson knew nothing of the legends!

Parnell Scott worked desperately against time, sinister foreign agents intent on keeping Henderson insane, and something as old as human history yet as new as tomorrow and more dangerous than nuclear energy.
