Zachary Nixon Johnson, the last private investigator on Earth, has another interplanetary issue on his hands. Merinda is a member of the High Council of Mars and is visiting the Earth. Someone wants her dead, and if Merinda dies the commercial relations between Mars and Earth will be seriously affected.

The audiobook version is much better than the kindle one, but since it was written for the readers to choose Zach's course of action, the moments he pauses to detail his options are odd and maybe they could have been edited out as they feel disconnected from the story. However, the voice actors did a beautiful job.
