A Portland, Oregon romance novelist who once published an essay called “How to Murder Your Husband” was arrested on September 5 on charges of murdering her husband with a gun.

Oregon chef Daniel Brophy was found shot to death on June 2. Seven years ago, his wife, novelist Nancy Crampton-Brophy had penned an essay titled How to Murder Your Husband.

“Dan was one of the very few people I’ve known that knew exactly what he wanted in life and loved doing it,” she said at a candlelight vigil two days after the demise of her husband of 27 years.

But on September 5, Crampton-Brophy, 68, author of romance mysteries such as Hell on the Heart and The Wrong Husband, was arrested for the murder.

Oregon police did not explain the three-month gap between the killing and the arrest.

“Detectives believe Nancy L. Crampton-Brophy is the suspect in Daniel C. Brophy’s murder,” said Portland police, who refused to discuss motive or evidence.

Daniel Brophy, 63, who was found dead in the Oregon Culinary Institute in Portland, had worked there as a chef for over 10 years.

Relatives were stunned by the news, and the author’s sister is convinced Nancy is innocent.

“None of us believe it,” said Holly Crampton. “It’s craziness and it’s just not true,” she told ABC News.

A neighbour of the Brophys from Beaverton, Oregon, recalled the writer saying she might move to escape her old life.

“She said that his side of the bedroom was haunting her,” Heidi Hutchinson told People.

Nancy Crampton Brophy is the author of several romance and suspense novels. Her series “Wrong Never Felt So Right” includes the book “The Wrong Cop” — it tells the story of a woman who fantasizes about killing her crooked police officer husband. Brophy’s author bio states that her “stories are about pretty men and strong women, about families that don’t always work and about the joy of finding love and the difficulty of making it stay.”

In 2011, Brophy posted the aforementioned prophetic essay on the blog “See Jane Publish.” It listed five motives and the kinds of weapons a romance novelist could choose from if she wanted to write about a character killing her spouse.

In the 700 word essay, since removed from the site, she explained that, “As a romantic suspense writer, I spend a lot of time thinking about murder and, consequently, about police procedure…After all, if the murder is supposed to set me free, I certainly don’t want to spend any time in jail.”

Brophy’s husband Daniel was gunned down on June 2 at the Oregon Culinary Institute where he worked as a chef. The next day, Brophy published an emotional Facebook post asking friends to withhold condolence phone calls because she was “overwhelmed.” She asked friends and family to, “please save phone calls for a few days until I can function.”

Brophy’s arrest earlier this month for Daniel’s murder came as a shock to family and friends. She has not entered a plea and the Washington Post reports that “a judge took the unusual step of sealing a probable cause affidavit in Crampton Brophy’s case at prosecutors’ request.”

On her author website, Brophy wrote about her husband of 27 years saying, “Like all marriages, we’ve had our ups and downs, more good times than bad.”
