The first Porfiry Rostnikov mystery I read by Stuart Kaminsky was one of the last one of the series. So I picked up A Fine Red Rain (his third) to gain some more background information. I was not disappointed.
Rostnikov sets out to investigate the deaths of two thirds of a high wire circus act (one a suicide and the other an "accident"). Rostnikov does not believe in coincidence, and when he interviews the third person in the act, he discovers that her life is in danger as well. The inspector finds that there is quite a bit of monkey business going on behind the scenes of the Moscow New Circus.
At the same time, Rostnikov's associates, Emil Karpo and Sasha Tkach are investigating cases of their own. Karpo is trying to track down a serial killer. Tkach has come across a black market for western goods. This subplot is quite fascinating, and gives us an interesting look at the extensive black market (along with accompanying police corruption) during the communist era.
Kaminsky's Rostnikov series is excellent, and I only regret that he hasn't been more prolific in writing these particular books. Fortunately for me, I have at least six or seven more to read. I'm already working on Rostnikov's Vacation.
