Sami, try reading anything by John Douglas especially Mindhunter and The Cases that haunt us.
He is basically a guy at the FBI who invented criminal profiling, he will walk into a crime scene and reel off without touching anything (sometimes just by looking at photos of the scene) who the person is they are looking for, sex, age, where they work, why they killed this person, who else they have killed, what they used, where they did it, etc etc. It is absolutely amazing. bit gruesom for a holiday but if you like true crime!!!
It's all true stories and the cases that haunt are cases that have never been solved (Jack the Ripper one is so interesting) and his views on if he had been around at the time what he would have done and who he thinks the offender was (includes the Lindbergh abduction and Lizzie Borden).
