I have just finished reading The Night Also Rises by C B McCullough (in the form of an e-book). His book is what I would describe as a hard-boiled mystery noir, set in the future, on a different planet. The only important difference between Earth and Jannix that I can detect, is the fact that the day (and night) lasts several weeks. Perhaps oddly enough, I enjoyed this book a lot (though I usually prefer cosy mysteries).
The main character is a middle-aged private investigator who gets an assignment by a famous millionaire. He's supposed to investigate the murder of the old man's son. Not surprisingly, not all is as it appears and the case becomes a life and death struggle. It seems that this is the first book in a series, but it can be read and enjoyed as a standalone.
