“There used to be a form of treatment for schizophrenics called insulin shock therapy. The patients would be brought in over the course of several weeks and regularly put into insulin shock, going deeper and deeper each time. Eventually, they’d be put into daily comas and brought out again after an hour or so. Not a very pleasant process, and the results were debatable. But I saw another use for the procedure. I devised a series of experiments to test different areas of the brain, to try to determine which one caused people to develop the sight. But to do this, I needed to re-create the conditions under which the sight develops. Namely, I had to bring the body into a state that mimicked the onset of death. Insulin shock therapy did just that. Paranormal neuropsychiatry, and I was the only person in the world qualified to practice it.

“My status as a Shade gave me unrestricted access, and they already knew me as a doctor. So I went back to the places I had worked before. My idea was simple. I would take the young people I’d met who had the sight, and I would say I was giving them experimental therapy. Getting insulin isn’t difficult, nor is the process of putting someone into a diabetic coma. It’s a bit of a risky procedure, but done carefully it causes no lasting harm. And I would be working on youths in the prison system, people already considered irredeemable. I performed my work for two years, taking the same subjects down about a dozen times each. I also conducted physical and psychological examinations.

“No one knew about this research of mine,” he continued. “I had planned on revealing it only when I had a clear result, at which point I would certainly have been given a proper lab and resources to continue. Finding out what controls the ability to see the dead? That’s a valuable asset. So I still did all of my normal duties—removing ghosts from buildings, getting trains working, all the mundane things they had us do. In my spare time, I did my real work. I had just located a fifth subject, a young girl. I began the process with her. To this day, I’m not sure what went wrong. I took her down—and she didn’t come back up. That’s when the powers that be discovered the work I’d been doing. They should have thanked me, despite the mistake. They didn’t.”

I was convinced now that Newman was telling us the truth. He may have been a murderer, and evil, but he was also honest. At least he was right now.
