Sins as Scarlet (Inspector Iwata)

After a brutal investigation ripped apart his life, Kosuke Iwata quit both his job as a detective with the Tokyo Police Department and his country, leaving Japan for the sunnier shores of Los Angeles, California. But, although he’s determined to leave his past behind, murder still follows him.

Having set up shop as a private investigator, Iwata is approached by someone from his old life. Her daughter has been killed and the case has gone cold. Out of loyalty, Iwata agrees to take on the case and reinvestigate the homicide. However, what seems initially like a cold-blooded but simple murder takes a complex turn when a witness, a vagrant, recalls the killer's parting words: “I’m sorry.”

From the depths of Skid Row to the fatal expanse of the Sonoran Desert, Iwata tracks the disparate pieces of a mysterious and heartbreaking puzzle. But the more he unearths, the more complex this simple act of murder becomes.

Lives untangle, fates converge, and blood is spilled as Inspector Iwata returns.
