Sandor Horvath is a student in international law at a university in Hungary. Trying to fit into the gadji world, he is unprepared when his younger brother steals his passport and his computer to sell what he finds in the hospital

Sandor is picked up by the Hungarians. His release is just before his final exam is to take place. He is denied his chance to graduate and sets out to find out what Invisible scheme his brother has caught him up in.

An intricately woven story that brings together many threads involving two countries and two different ideologies, INVISIBLE MURDER is a strong statement about the indignities that society inflicts on people who don't fit into their conception of normal. While the story is strong, I found it hard to follow because the authors did a lot of scene hopping; both in time and location. If you like dark mysteries, this will meet your needs. For those who like cozies or light mysteries, this will depress you.
