CONSPIRACY OF GENIUS His height barely reached five feet, his spindly legs supported a bulging chest, and his eyes protruded grotesquely from a gnome-like head - but within that absurd-looking man lay the mind of a genius. It was a genius that had carried mankind deep into the secrets of creation and was now on the verge of producing living organisms from test tubes filled with inert chemicals. The world, however, ridiculed the theories of Professor Cheslin Randolph and the government refused to advance the millions needed for the final series of experiments. But Professor Randolph was determined to get the money - even if it meant turning his powerful brain to robbing a spaceship in mid-flight, using trained viruses as his accomplices.

Scobie Redfern was just a nice good-looking American young man who had never heard of such things as Portals, parallel worlds, and Trugs. So when someone materialized in his apartment with the Trugs in hot pursuit, it all seemed sort of a funny game. But there was nothing amusing about it once the monsters themselves arrived. For it wasn't long before Scobie was himself running for his life from world to world and from Portal to Portal just to keep one jump ahead of the Trugs, and hoping that the Wizards of Senchuria might, just might, be able to get him back home alive and whole!

Among the myriad colourful characters of the galaxy, men called him a Treasure Troubleshooter. His name was Felix Vereker, and he liked good food and fine wines and his taste ran to Moliere and ancient legends and digging up the fabulous treasures of the past - on whatever planet they happened to be buried. He did not relish the distraction of political assassination, or mysterious attempts on his own life, or the prehistoric savagery and barbarian swords of a playground world of bored millionaires. But when his professional competence as a troubleshooter for a firm of galactic antique dealers demanded, he could be rougher and tougher than all the perils pitted against him. And he knew how to handle Delia Camacho, the lady assassin, and Miss Rosalind Henley - who demanded and then rejected more than he wanted to give. This novel of future speculation and intrigue ranges a wide galactic canvas and a profusion of brilliant colourful incidents pours out in headlong action as Felix Vereker seeks control of his own identity.
