I slipped in the window, which had been left open for me. The crime scene had been processed; the coroner’s on-site prelim completed. The only person in the room besides me was Detective Sergeant Patrick Mulligan. I knew Mulligan – he was an honest cop who admitted that sometimes, a costume could handle things a uniform couldn’t. At the same time, I was not on the Boston PD’s list of approved people to call in, which meant that he wasn’t sure the PD could handle it. Or there was another reason. A call on the way over to my contact in the coroner’s office confirmed it for me.
