Dakos was an alien humanoid who hated earth; he detested the planet; its people were anathema to him. He loathed its cities; its countryside was an abomination to him. He lived for one thing only… the destruction of the world which had rejected him.
Dakos was no mean enemy. His hatred was allied to a brilliant mind and a very superior technology. He was a man of action… highly destructive action!
Security agents Blanthus and Croberg were after him, but Dakos covered his tracks with all the cunning of a diabolically clever homicidal maniac.
He could so easily pass as a terrestrial humanoid.
…Are you sure that man sitting beside you in the bus isn’t the alien? What’s in that case?
His clothes? His lunch? His business documents? Or an alien bomb?
This is the story of a world reeling from a war of nerves with a sinister secret enemy.
