War on Aleph — Laurence James

It is five hundred years in the future. Strange new worlds and alien races have evolved. The universe as we know it has become a densely populated community. Interplanetary travel is now a routine matter. - In this fascinating world of tomorrow the Inter-Galactic Security Service is at work fighting the forces of crime and evil - still very much a part of society's problems. Commander Simon Kennedy Rack and his assistant, Ensign Bogart, are special agents of the I.G.S.S. As a team, they are given the tough, nearly impossible assignments - and they pursue their work with ferocious brilliance.
