Plot summary
After being forcibly divorced from his wife for political reasons, Spencer tries to force his way on board the ship she’s on. After being ejected, he gets drunk and implanted with a "feelgood" device that stimulates the pleasure centers of the brain. Spencer is saved from this addictive and lethal fate by an unknown Kona Tatsu agent. They clean and care for him, then send him on a mission to the Daltgeld system. Working with Agent Suss Nanahbuc, Spencer is given command of a task force and told that Kona Tatsu agents are disappearing from the planet. Upon arrival, the ``Duncan`` splashes down to dock for repairs, and Nanahbuc heads out to learn the fate of the other agents. While docked, Spencer gets a visit from McCain, a KT agent hiding from the enemy. However, the enemy is aboard and kills McCain before they can analyze the data she found. The enemy turns out to be a small mercury-like blob that seems to react to its environment, weighs 16 tons, and can control the devices it infects. Spencer leaves the ship and closes it down tight, but it’s already too late. In the end, it turns out an alien artifact was recently discovered in an asteroid, and the captain of the mining freighter was "convinced" to take the artifact to the head of a local conglomerate, Jameson. The device, a helmet made of a mercury-like substance, takes over Jameson and uses him as a control center for taking over the system, with plans to leave it and spread throughout the galaxy. After losing his flagship to prevent an alien from leaving the system, Spencer and Nanahbuc locate the main asteroid of the enemy and head in with the task force to put an end to it for good.
