The Assassin Drug.

BOOK 4. Shen Wei is a doctor working in accident and emergency but also Black Robe. Zhao is a detective chasing bank robbers when he first meets Black Robe thinking that he is one of them and shoots him. The story is about their relationship and their search to stop a drug which turns normal people into assassins, this drug has followed through in all my books, sometimes only in the background. Maybe this time they will destroy it completely. I hope you enjoy the book as much as I did writing it.
