Nocturnal, perpetually exhausted private detective Robert Lee's life is changed one morning when he receives a visit from a peculiar man desperate to find his missing sister. The only problems are that the sister has been missing for over a month and there are no tangible leads. Forced deeper into the case by necessity and a morbid fascination, Lee uncovers a dangerous mystery perpetuated by people not unlike himself: morally ambiguous, inherently cynical and irretrievably lost. Compelled to continue wading through the darkness, the detective soon realizes that the darkest demons in the city of angels might be those that lurk in the corners of his own heart. All the way up until the shocking conclusion, Nocturnal is a gripping tale of a broken man lost in a shadowy haze of corrupted souls, with his path illuminated only by the discerning eye of nighttime.
