What color is murder?

A well-known multimillionaire is murdered in front of several hundred spectators. His death seems inevitable — he had made quite a few enemies. If not for one "but" — the victim knew in advance that someone was already preparing a... bullet for him. He was kindly notified of this in a letter.

The witness to the crime is popular coach and human behavior specialist Alex King. Acting as a consultant to the police, he teams up with Inspector Nina Mander to investigate.

The foundation of King's method is based on a very real approach to color typology of human characters. It is also dedicated to the psychological super bestseller by the author of "Surrounded by Idiots," which explains how to accurately read people's thoughts and predict their actions through color typology. But will this approach work in the case of investigating a high-profile crime? Will the hero manage to figure out "what color" the killer is? Especially since the killer has already marked a new victim.
