“She’s right, you know, sahib,” Bob said brightly. “If you’d just do something with your hair and wear nicer clothes, you’d find a woman. You’re a doctor, after all. What woman doesn’t want to marry a doctor?”

“Did he just get a little Yiddish accent?” I asked Butters.

“I get it twice a week already, Bob,” Butters growled. “I don’t need it from you, too.”

“Well, you need it from somewhere,” Bob said. “I mean, look at your hair.”

Butters ground his teeth.

“Anyway, Harry,” Bob began.

“I know,” I said. “The thing I saw with the Grey Ghost must be the piece that you cut off.”

“Right,” he said. “Got it in one.”

“Your offspring, one might say.”

The skull shuddered, which added a lot of motion to the bobblehead thing. “If one was coming from a dementedly limited mortal viewpoint, I guess.”

“So it’s a part of you, but not all of you. It’s less powerful.”

Bob’s eyelights narrowed in thought. “Maybe, but… the whole of any given being is not always equal to the sum of its parts. Case in point: you. You aren’t working with a lot of horsepower in the brains department, yet you manage to get to the bottom of things sooner than most.”

I gave the skull a flat look. “Is it stronger than you or not?”

“I don’t know,” Bob said. “I don’t know what it knows. I don’t know what it can do. That was sort of the whole point in amputating it. There’s a big hole where it used to be.”

I grunted. “How big?”

Bob rolled his eyes. “Do you want me to tell you in archaic measurements or metric?”

“Ballpark it.”

“Um. A hundred years’ worth of knowledge, maybe?”

“Damn,” I said quietly. I knew that Bob had once been owned by a necromancer named Kemmler. Kemmler had fought the entire White Council in an all-out war. Twice. They killed him seven times over the course of both wars, but it didn’t take until number seven. Generally remembered as the most powerful renegade wizard of the second millennium, Kemmler had at some point acquired a skull inhabited by a spirit of intellect, which had served as his assistant.

Eventually, when Kemmler was finally thrown down, the skull had been smuggled away from the scene by a Warden named Justin DuMorne—the same Justin who had adopted me and trained me to grow up into a monster, and who had eventually decided I wasn’t tractable enough and attempted to kill me. It didn’t go as he planned. I killed him and burned down his house around his smoldering corpse instead. And I’d taken the same skull, hidden it away from the Wardens and company, and named it Bob.

“Is that bad?” Butters asked.

“A bad guy had the skull for a while,” I said. “Big-time dark mojo. So those memories Bob lost are probably everything he learned serving as the assistant to a guy who was almost certainly the strongest wizard on the planet—strong enough to openly defy the White Council for decades.”
