"The Queens."
I frowned. "Tell me if I'm off track here. If it comes from the Queens, it's a part of them, right? If a Knight dies, the power should snap back to the Queen like it was on a rubber band."
"Exactly."
"But this time it didn't. So the Summer Queen is missing a load of power. She's been weakened."
"If everything you've told me is true, yes," Bob said.
"There's no more balance between Summer and Winter. Hell, that could explain the toads. That's a serious play of forces, isn't it?"
Bob rolled his eyelights. "The turning of the seasons? Duh, Harry. The Sidhe are closer to the mortal world than any other beings of the Nevernever. Summer's had a slight edge for a while now, but it looks like they've lost it."
"And here I thought global warming was due to cow farts." I shook my head. "So, Titania loses a bunch of juice, and naturally suspicion falls on her archenemy, Mab."
"Yeah. It is kind of an archenemy-ish thing to do, you have to admit."
"I guess." I frowned down at my notes. "Bob, what happens if this imbalance between the Courts continues?"
"Bad things," Bob said. "It will mess around with weather patterns, cause aberrant behavior in plants and animals, and sooner or later the Sidhe Courts will go to war with one another."
"Why?"
"Because, Harry. When the balance is destroyed, the only thing the Queens can do is to blow everything to flinders and let it settle out into a natural distribution again."
"What does that mean to me?" I asked.
"Depends on who has the edge when everything is settled," Bob said. "A war could start the next ice age, or set off an era of rampant growth."
"That last one doesn't sound so bad."
"No. Not if you're an Ebola virus. You'll have lots of friends."
"Oh. Bad, then."
"Yeah," Bob said. "Keep in mind that this is theory, though. I've never seen it happen. I haven't existed that long. But it's something the Queens will want to avoid if they can."
"Which explains Mab's interest in this, if she didn't do it."
"Even if she did," Bob corrected me. "Did she ever actually tell you she was innocent?"
I mulled it over for a moment. "No," I said finally. "She twisted things around a lot."
"So it's possible that she did do it. Or had it done, at any rate."
"Right," I said. "So to find out if it was one of the Queens, we'd need to find her hitter. How tough would it be to kill one of these Knights?"
"A flight of stairs wouldn't do it. A couple of flights of stairs wouldn't do it. Maybe if he went on an elevator ride with you - "
"Very funny." I frowned, drumming my pen on the table. "So it would have taken that little something extra to take out Reuel. Who could manage it?"
"Regular folks could do it. But they wouldn't be able to do it without burning buildings and smoking craters and so on. To kill him so that it looked like an accident? Maybe another Knight could. Among the Sidhe, it was either the Winter Knight or one of the Queens."
"Could a wizard do it?"
"That goes without saying. But you'd have to be a pretty brawny wizard, have plenty of preparation and a good channel to him. Even then, smoking craters would be easier than an accident."
"The wizards have all been in duck-and-cover mode lately. And there are too many of them to make a practical suspect pool. Let's assume that it was probably internal faerie stuff. That cuts it down to three suspects."
"Three?"
"The three people who could have managed it. Summer Queen, Winter Queen, Winter Knight. One, two, three."
"Harry, I said it could have been one of the Queens."
I blinked up at the skull. "There are more than two?"
"Yeah, technically there are three."
"Three?"
"In each Court."
"Three Queens in each Court? Six?" That's just silly."
"Not if you think about it. Each Court has three Queens: The Queen Who Was, the Queen Who Is, and the Queen Who Is to Come."
"Great. Which one does the Knight work for?"
"All of them. It's kind of a group thing. He has different duties to each Queen."
I felt the headache start at the base of my neck and creep toward the crown of my head. "Okay, Bob. I need to know about these Queens."
"Which ones? The ones Who Are, Who Were, or Who Are to Come?"
I stared at the skull for a second, while the headache settled comfortably in. "There's got to be a simpler parlance than that."
"That's so typical. You won't steal a baby, but you're too lazy to conjugate."
"Hey," I said, "my sex life has nothing to do with - "
"Conjugate, Harry. Conju - oh, why do I even bother? The Queen is just the Queen. Queen Titania, Queen Mab. The Queen Who Was is called the Mother. The Queen Who Is to Come is known as the Lady. Right now, the Winter Lady is Maeve. The Summer Lady is Aurora."
"Lady, Queen, Mother, gotcha." I got a pencil and wrote it down, just to help me keep it straight, including the names. "So six people who might have managed it?"
"Plus the Winter Knight," Bob said. "In theory."
"Right," I said. "Seven." I wrote down the titles and then tapped the notebook thoughtfully and said, "Eight."
"Eight?" Bob asked.
I took a deep breath and said, "Elaine's alive. She's on the investigation for Summer."
"Wow," Bob said. "Wow. And I told you so."
"I know, I know."
"You think she might have gacked Reuel?"
"No," I said. "But I never saw it coming when she and Justin came after me, either. I only need to think about if she had the means to do it. I mean, if you think it would have been tough for me, maybe she wasn't capable of taking down Reuel. I was always a lot stronger than her."
"Yeah," Bob said, "but she was better than you. She had a lot going for her that you didn't. Grace. Style. Elegance. Breasts."
I rolled my eyes. "So she's on the list, until I find some reason she shouldn't be."
"How jaded and logical of you, Harry. I'm almost proud."
I turned to the folder Mab had given me and went through the newspaper clippings inside. "Any idea who the Winter Knight is?"
"Nope. Sorry," Bob said. "My contacts on the Winter side are kinda sketchy."
