The World Swappers by John Brunner 

The Galaxy was caught in the crushing vice of a struggle for power. The political titans of the planets of Mankind were making their bids for supremacy. The contestants: Counce, man of strange powers, authority in the spheres of intellect; and Bassett, man of money-powers, financial and business wizard. As the association of human worlds drew near the teetering edge of revolution, one of those men would be ina position to triumph. The only thing that neither side could foresee was that there were OTHERS hovering among the stars, looking for new worlds to conquer!

Seige of the Unseen by A E Van Vogt

THE THREE EYES OF EVIL

“The crash was over, the car on its side. Slade sprawled dizzily on his back, while something warm trickled from his forehead into his left eye. He wiped it away, and saw with a start that it was blood. The skin was torn raggedly . . . ”

“A third eye was plainly visible. The eyelid of it was closed by a surplus of sticky matter, but abruptly he grew aware that it was pulsing with a vague perception of light . . . ”

At first it was a grotesque discovery, when the accident revealed that young businessman Michael Slade was a bizarre freak — a man with three eyes. But the impact of what it meant to see with three eyes was even more macabre. For Slade, that shocking third eye was his entry into a strange new dimension of terror and adventure — a fearful new world that would wrap itself about him forever!
