One morning in September 2016, a person sat in their home in Bucks County, Pennsylvania, holding a business card. Like always, the sight of it made their stomach twist into knots. The card had been given to them years ago by a detective, and it was worn and faded from all the times the person had turned it over in their hands, agonizing over what to do with it. The detective had been looking for leads in a murder case, and at the time, the person said they had nothing to share. But that was a lie – they actually did have information about that murder, and had kept it a secret for years. Now, over two decades later, they’d finally decided to tell the truth. But they were scared. Because they knew when they did – nothing would ever be the same.
