The Portero Method — F. Paul Wilson

Second in F. Paul Wilson's series of thrilling novellas about a time and place very much like our own except for one major difference: the science of recombinant genetics has leaped decades beyond what we know today.

In Book Two -- The Portero Method -- SimGen ratchets up its relentless pressure -- both personal and professional -- on Patrick Sullivan to drop the sims' cause. With his friends, legal associates, even his lover turning against him, Patrick is ready to throw in the towel when, seemingly out of the blue, help arrives in the form of a beautiful woman.

An unnamed, amorphous fifth column in the brave new world of the sims decides to show its hand and underwrite Patrick's efforts. To further bolster his resolve, Romy Cadman, the organization's point woman, shows him the seedy, exploited side of sim life, never realizing that tragic death waits in the wings.
