Disciples of the Comet

It is the 24th century as men record time. A serial killer on the colony planet of New Madrid has drawn the attention of Space Marshal Otis McHenry Kidd. A series of murders have coincided with the close return of a comet. These crimes which have occurred at fifty year intervals for two hundred years have been tied to one man. What Marshal Mac Kidd uncovers on this obscure world located at the edge of the inhabited planets is more than anyone bargained for and will change the course of human history.
