So let's get back to January 1990, six months after Collier saw his father kiss Sherry. Collier's mother has just disappeared, and he's reporting to Lieutenant Dave Messmore regularly with clues. The kissing, the ring, all of it. Dave doesn't exactly jump up and down with excitement.

He's writing it down in his little book. Dave doesn't say much because Dave didn't have much. He hadn't been able to find Noreen, and Dr. Jack Boyle still wouldn't talk to him. So with little else to go on, Dave decided to dig into the good doctor a little bit more. He started hearing stories, lots of them.

In fact, Jack came from a modest family. His dad was a firefighter, and Jack didn't grow up with privilege. He'd gone to medical school on a scholarship and also had a part-time job. By that point in Dave's investigation, he'd started interviewing nurses.

Dave was a family man. Family meant a lot to him. And this philandering thing, it offended him.

As if that wasn't enough, the woman said Jack had left something disturbing for her. It was a photograph of himself dressed in his former white Navy uniform, dozens of medals pinned to his chest, standing with his arm around a much younger woman.

And what about Collier's favorite story, the one about Dr. Jack Boyle's heroism on the high seas during the Vietnam War?

Of course, when his mother first disappeared, Collier didn't know most of this. What he did know was that his mother was gone, his father was involved with another woman, and something felt very, very wrong. And then, according to Collier, on January 1st, just one day after Noreen went missing, the Boyle household got a visitor.
