Dirty Proof is the first mystery I wrote, and I was inspired to write it both because I’m a life-long mystery fan and because, at the time, I was working as a typesetter at the Chicago Tribune and was so taken by the setting that I vowed to write a mystery featuring it.
In order to write the story I created my detective, Frank Dragovic, from Chicago’s south side Croatian community. Next, I created the crime and the murder victim, Ralph Blasingame, and the newspaper he worked for, The Chicago Truth-Examiner. After that I created Frank’s client, Suzanne Quering, who is suspected of murdering Blasingame. Thus, with a detective, a client, and a crime, I proceeded with the story.
Along the way I had to create more characters, some of them suspects and some of them not. Some of them major characters, some of them minor. All of them in the newspaper trade, but each with a different job and thus a different outlook on matters. Creating the characters, their motives, and their work environment was fun for me, and I suspect that all novelists enjoy this part of writing the book.
What was difficult for me was deciding on who the murderer was. I rewrote the novel three times, and each time I changed the murderer and the motive. (This wasn’t the case when I wrote the sequel, Sound Proof — I knew from the beginning who the murderer was, and that never changed.)
Over the years, people have told me that what they remember most about Dirty Proof is the crime, the newspaper setting, and the ending. I like knowing that what inspired me to write the novel — the setting and the crime — is what resonates with readers.
