It seems like a simple assignment for two experienced Special Space Agents. On Affix, one of the two moons of Viridis, the most distant planet in the human-explored and inhabited part of the universe, Monterrey and Xiaobo, two agents of the Federal Bureau of Space Investigation, are hunting a fugitive. The FBSI agents expect to get the job done quickly. Until it turns out that several more parties are involved in the manhunt. And not all of these parties are human ... When an ancient secret is also uncovered, a dangerous cat and mouse game is created. A game of life and death. To survive, criminals and men of the law have only one choice. They must work together to defeat the unknown enemy. Collaborate with someone they don't trust.

When Taylor & Balon investigate a complex murder case, they become entangled in a world of deceit and manipulation. Who can you rely on if you don't know who your friends are?

After all these years they have to rely on each other again. Have to trust each other again. They must find the assassin, before he will murder them all.  Only one thing they know for sure. One of them is the murderer…
