It was as if the couple had gone on the same vacation tour every day, over and over again, collecting the same general batch of pictures each time.

“Matching T-shirts,” I said. “Creepy.”

Murphy’s smile was unpleasant. She was a tiny, compactly muscular woman with blond hair and a button nose. I’d say that she was so cute I just wanted to put her in my pocket, but if I tried to do it, she’d break my arm. Murph knows martial arts.

She waited and said nothing.

“Another suicide pact. That’s the third one this month.” I gestured at the pictures. “Though the others weren’t quite so cuckoo for Cocoa Puffs. Or, ah, in medias res.” I shrugged and gestured at the obsessive photographs. “This is just crazy.”

Murphy lifted one pale eyebrow ever so slightly. “Remind me: How much do we pay you to give us advice, Sherlock?”

I grimaced. “Yeah, yeah. I know.” I was quiet for a while and then said, “What were their names?”

“Greg and Cindy Bardalacki,” Murphy said.

“Seemingly unconnected dead people, but they share similar patterns of death. Now we’re upgrading to irrational and obsessive behavior as a precursor…” I frowned. I checked several of the pictures and went over to eye the bodies. “Oh,” I said. “Oh, hell’s bells.”

Murphy arched an eyebrow.

“No wedding rings anywhere,” I said. “No wedding pictures. And…” I finally found a framed family picture, which looked to have been there for a while, among all the snapshots. Greg and Cindy were both in it, along with an older couple and a younger man.

“Jesus, Murph,” I said. “They weren’t a married couple. They were brother and sister.”
