After completing bachelor’s and master’s courses at the Seoul National University School of Law, Jin-Ki Do served as the presiding judge of Seoul District Court. At present, he divides his time between practicing law and writing mystery fiction. Do's debut was in 2010, when his short story Choices received the New Mystery Writer Award from the Korea Mystery Writers Association. Do’s works include Murder at the Red House, featuring lawyer Ko Jin, The Portrait of La Traviata, Mental Suicide, featuring Jin-Ku as the main character, The Problem of Order, and The Man Who Knows Me. Four of Do’s fiction titles have been exported to China. Do’s detective fiction has garnered a strong fan base of mystery readers for its brilliant tricks and intellectual games. Publication of the educational book Who Killed the Little Match Girl? was part of Do’s effort to present law in simple and interesting terms to the general public.
