The Escort Service

The end of veneral diseases has come. A person can now rent an android or a gynoid with interchangeable parts for one night stands, as a casual relationship, as a perfect escort, or simply to fool one's friends into thinking you're sleeping with a hunk or hot babe. Once the android or gynoid is returned to the escort service it is sterilzed and prepped for the next client. All goes wrong though when the president of the service is murdered.
Was the killer human or robot? In this world it is not easy to tell the humans from the robots. Irene, a flashy free spirit, knows the suspects are great in number. However, there's a certain android who is able to satisfy all her whims and fancies that she definitely wants to save from final dismantling. She'll find the real killer or die trying.
