It sounds like she has something specific in mind, but I’m sure it’s something stupid. “Look, he’s not a killer.”

She lets out an exasperated sound. “Don’t you get it, Brooke? It had to be him. He’s the only one who had the opportunity. He was alone in the living room and he could’ve gone up and killed her. Nobody else had the chance to do it.”

I chew on my lower lip. My lips have gotten very chapped in the last couple of weeks, as the weather has turned. Licking them and biting them makes it worse, but I can’t help it.

“Actually,” I say, “one other person had a chance.”

“Who? Shane was outside. And nobody else is here. Who else had a chance?”

“You.” I try to pick out her features in the dark room, but all I can see are her dark eyes with leaked mascara. “You were alone in the living room when Tim and I were in the kitchen.”

Her jaw falls open. “Excuse me?”

“Well,” I say thoughtfully. “It does make sense. More sense than Tim or Shane randomly killing Brandon and Kayla. I mean, Brandon was cheating on you. A lot. And then Kayla was accusing you of killing him. It stands to reason—”

“Oh, this is good!” Chelsea sounds like she’s trying to be sarcastic, but there’s a slightly hysterical edge to her voice. “First my boyfriend is murdered and I have to find his dead body. And now you think I killed him, and apparently busted down Kayla’s door and did her in as well?”

“No, I’m not saying that,” I say carefully. “I’m just pointing out that you had an opportunity and a motive.”

She stands there for a moment, her silhouette completely still. “If I am the one who killed them, why am I bothering to look for a weapon? If I did it, that means I’ve got a knife stashed away somewhere, doesn’t it?”

“I… I guess so.”

“Damn straight.” She shakes her head. “I mean, you are seriously out of your mind if you think that I’m capable of killing two people.”

My stomach churns as a thought hits me. Tim was looking for the knife while Chelsea and I were in the house. He didn’t find it, but that was information he told to me alone. So how could she know the killer has a knife stashed away? Unless…

“I think we should go downstairs.” I scramble to my feet. “I want to make sure the guys are okay. And… I think it’s better if we’re all together.”

“Are you crazy? For all we know, Tim has already stabbed Shane to death, and he’s waiting for us at the bottom of the stairs!”

“No,” I say firmly. “He’s not.”
