The 1970s! Disco! Abba! The Eagles! Richard Nixon. The end of the Vietnam War. Women’s Rights. And, umm, yeah, other stuff. I was born mid-decade and have no real memories of the 1970s. Writing about the 1970s, for me, isn’t a matter of “write what you know,” but rather one of “research what you need to know.”
When editor Michael Bracken asked me to submit a story for the Private Dicks and Disco Balls: Private Eyes in the Dyn-O-Mite Seventies (Down & Out Books, May 2024) I read the requirements, which specified including some historical event from the 1970s, and knew I would have to dive into research.
I began searching for events of the 1970s with the help of the internet and my local library card. Logging into my local library online gave me access a plethora of research material, including the archives for Time Magazine (1923-2000), Life Magazine (1936-2000), one hundred years of The Austin American Statesman (1871-1980), and access to Newspapers.com for free. I skimmed or read news articles from major newspapers covering crime, disasters, and political issues of the 1970s. Women’s rights issues, including Title IX, employment protections, and the attempts to pass the Equal Rights Amendment, recurred in my search, leading me to the event I needed for the story: the Battle of the Sexes tennis match between Billie Jean King and Bobby Riggs. The Battle of the Sexes took place in Houston in September 1973.
I even found video from the era, including video from the tennis match itself. Archived videos are fabulous research resources. I discovered news broadcasts from Houston during the 1970s and watched several segments. The benefit of video in research for writing can’t be overstated. Watching news broadcasts provided glimpses of linguistic quirks, clothing styles, hair styles, technology, and automobiles of the 1970s. The insane way (by today’s standards) in which reporters wandered into crime scenes, shoved microphones into the face of working doctors in hospitals, and even sickened themselves while reporting on chemical disasters fed into my understanding of the decade. If a reporter could get away with that much, a private investigator could do that and more.

My research uncovered regulations on who could and couldn’t be a police officer, leading me to articles explaining how, for decades, the height requirement for the Houston Police Department eliminated all the Hispanics who applied for the police academy. The height requirement was changed in the early 1970s to allow for greater diversity in the department. I learned how women’s roles in police departments were limited and about efforts to remove those limits. This research helped in the creation of one of my secondary characters for the story: a petite, Hispanic woman with quashed aspirations for law enforcement.
In researching fires and industrial accidents, I found articles on hazardous materials being routed through Houston and the dangers they posed. I read calls for the creation of hazardous material routes around big cities. Then I reached out to an expert with knowledge of industrial explosives from the 1970s to 2000s. My father worked as an insurance underwriter for a special risk program that included insuring businesses that manufactured, distributed, or used things that go “BOOM.” He had to learn a lot about explosives. He was, and is, a fount of information.

As I worked, I learned more than I needed for my story, and the research began to coalesce into a plot involving my detective, Jerry Milam, in an arson investigation that led him from Austin to Houston during the week of the Battle of the Sexes tennis match. Jerry Milam previously appeared in Groovy Gumshoes: Private Eyes of the Psychedelic Sixties, (Down & Out Books, 2022, edited by Michael Bracken) in a story entitled “Nice Girls Don’t.”
They say “write what you know,” but the caveat to that is “learn what you need to know.” I researched what I didn’t know and I melded it with what I already knew. I was already familiar with my setting in Houston, although I did consult a few maps. Describing Houston is easy for someone who was born there and visits the city regularly. Also, tucked into the story are details that I know because I have an affinity for trivia, including details that my PI would have known: like who was Red Adair (hint: John Wayne played a version of him in The Hellfighters) and what happened in Texas City in 1947 (hint: worst industrial accident in US History).
My local library online research resources are phenomenal and are my favorite place to browse when I need very specific historical information. Reaching out to experts is also beneficial for getting the nitty-gritty details right. Do you have favorite research sites? Where do you look when you need accurate information quickly?
