When Sam Kornberg’s wife, Lala, walks out on him, he’s an unemployed used-book store clerk and failed experimental novelist with a broken heart. Desperate to win her back, he takes a job as assistant detective to the enigmatic Solar Lonsky, a private eye who might be an eccentric and morbid genius or just a morbidly obese madman.

It’s a simple tail job, following a beautiful and mysterious lady around L.A., but Sam soon finds himself helplessly falling for his quarry and hopelessly entangled in a murder case involving Satanists, succubi, underground filmmakers, Hollywood bigshots, Mexican shootouts, video-store geekery, and sexy doppelgangers from beyond the grave. A case that highlights the risks of hardcore reading and mourns the death of the novel - or perhaps just the decline of Western civilization.

Mystery Girl is a thriller about the dangers of marriage and a detective story about the unsolvable mysteries of love, art, and other people.
