DCP Rita Ferreira is called into the investigation after a third corpse is discovered in Mumbai, which confirms it is the work of the same killer who paints his victims's lips with dark red lipstick.

The Lipstick Killer, like all serial killers, is fast decompensating—the time interval between the murders shortening, the victims shifting from street-side hookers to high-heeled wives ... and he watches everything and everyone—the news of his exploits, Rita, the investigation—and talks. However, he only talks to you: "When I'm gone, some people may tell you that I was evil, perhaps even call me a psychopath. Don't believe them. I am not. I am anything but irrational and impractical; perhaps only slightly more detached than your average guy on the street."
