The Jigsaw Assassin - Catherine Asaro - Bog

"When a serial-killer plot points to the Royalist political party, Major Bhaajan, former military officer turned private detective, is called back to Selei City to solve the crime. Bhaaj and her crew of Undercity Dust Knights plunge into the Byzantine world of Imperial politics--a jigsaw world where none of the pieces seem to fit. As the assassination plot becomes more and more convoluted, Bhaaj is kidnapped and must fight for her life against the growing number of people threatened by her investigation. Bhaaj has faced all this and more before, but now she must deal with something far deadlier--interstellar politics."--
