The Detective Inspector Chen Novels Volume One: Snake Agent, The Demon and the City, and Precious Dragon

Three paranormal mysteries featuring Detective Inspector Wei Chen of Singapore Three's Thirteenth Precinct, whose jurisdiction extends to the supernatural realms of Heaven and Hell. Chen works alongside Zhu Irzh, a demon from Hell's vice squad, to investigate cases beyond the mortal world. Snake Agent introduces Chen as an occult detective with an unusual comfort around the supernatural—his wife is a demon. When he must journey to Hell to locate the ghost of Pearl Tang, a wealthy industrialist's deceased daughter, he discovers that escaping the underworld proves far more difficult than entering it. The Demon and the City follows Zhu Irzh as he aids the Singapore Three police department while Chen takes a vacation. Investigating the brutal murder of a would-be witch at an occult market, Zhu Irzh uncovers a supernatural conspiracy that reveals evil exists beyond Hell's borders. Precious Dragon sends Chen and Zhu Irzh to escort a Heavenly functionary, Mi Li Qi, on a diplomatic mission to the underworld. When Qi disappears into the abyss, they must navigate demonic bureaucracy and otherworldly dangers to prevent a political catastrophe.
