Madison Kelly, a San Diego private investigator, arrives home to a note stabbed to her front door: "Stop investigating me, or I will hunt you down and kill you." The only problem?

The only way to remove the threat is to do exactly what "Anonymous", the note writer, is telling her not to do: investigate to see who left it. Could this have something to do with the true crime podcast she's been tweeting about, and the missing girls?
