Search - Extremes (Retrieval Artist, Bk 2)

From back cover:
His name: Miles Flint.
His occupation: Retrieval Artist.
His job: Find the Disappeared--outlaws on the run, wanted for crimes against alien cultures.
The catch: Flint isn't working on the side of the law anymore.

One simple mistake and a Disappeared could end up dead. But this time, the death of an ailing Retrieval Artist has caught Flint's attention. He suspects it was foul play, not a viral infection. Equally suspicious is a young woman's sudden demise during the Moon's prestigious Extreme Marathon. As Flint investigates, he finds an ominous connection: Both deaths lead back to a scientist. A scientist who is now one of the Disappeared.

An excellent blending of a police detective mystery and science fiction. Kristine Kathryn Rush proves that all those years she spent giving us Pulphouse Magazine, and editing The Magazine of Fantasy and Science Fiction, she was depriving us of some truly great novels.

2nd in the Retrieval Artist series. A good story with more development of the original characters.
