This article about Hans Reiser is amazing. I haven't heard about this case until now, but it seems very interesting. I found it hard to believe at first as it sounds so unreal; murder/disappearance, troubled relationships, international, eccentric protagonist

(suspect), custody battles, secret messages in code, sex and drugs, serial killers, and Russian Mafia and spy agency.

This is not a work of fiction, although it is sensationalised in many respects.
