Last Son of Cain

"The last son of Cain" is the first installment of the #Blackcoast saga about the private detective Martín Costa, a criminal profiling retired after the murder of his wife and who will be involved in different murder cases once again as he participates as an advisor in the search for a psychopath nicknamed the Master, who will become his particular Moriarty while pursuing different criminals throughout the saga. Intuitive, disgustingly intelligent and with a striking humorous point, Dr. Costa will even see old ghosts and worse nightmares reborn. Throughout the saga he will be accompanied by invaluable companions such as Inspector Irene Sanleón, with whom he will have a strange romance / attraction, Inspector Ricardo Dobico or Commissioner Gabriel Brescia.
In this first installment and his first face to face with the Master, he will try to find out who is behind the serial murders that plague the streets of the city of Santiago. Each corpse is a perfect reconstruction of the signature, modus operandi, and victimology of a famous serial killer from the past.
Martín Costa will understand that he is before the perfect murderer. The question is: will he be able to find him and prevent the deaths from accumulating victims to the case?
