A is for Alibi

I could kill him again."
    She looked at me fully then and the enormity of what she was saying began to sink in.
    "What about Nikki? What did she ever do to you?"
    "I thought they'd acquit her," she said. "I never thought she'd go to jail, and when the sentence was handed down I wasn't going to stand up and take her place. By then it was too late."
    "So what else?" I said and I noticed that my tone was getting sullen. "Did you kill the dog too?"
    "I had nothing to do with that. He got hit Sunday morning. I drove Diane over there because she'd remembered that she'd left him out and she was upset. He was already lying in the street. My God, I wouldn't run over a dog," she said emphatically, as though I should appreciate the delicacy of her sentiments.
    "And the rest just fell into place? The oleander in the yard? The capsules upstairs?"
    "One capsule. I doctored one."
    "Bullshit, Gwen. That's bullshit."
    "It's not. I'm telling the truth. I swear to it. I'd thought about it for a long time but I couldn't see a way to make it work. I wasn't even sure it would kill him. Diane was a wreck about the dog anyway so I drove her to my place and put her to bed. As soon as she was asleep, I took her keys and went back and that's all it was." She spoke with an edge of defiance, as though having opened up this far there was no point in mincing words.
    "What about the other two?" I snapped. "What about Sharon and Libby Glass?"
    She blinked at me, pulling back. "I don't know what you're talking about."
    "Oh the hell you don't," I said, getting up. "You've lied to me since the first minute we met. I can't believe a goddamn word you say and you know it.
    She seemed startled by my energy. "What are you going to do?"
    "Give the information to Nikki," I said. "She paid for it. We'll let her decide."
    I moved away from the table, heading toward the door. Gwen grabbed her jacket and purse, keeping pace with me.
    Out on the street, she snatched at my arm and I shook her off.
    "Kinsey wait" Her face was remarkably pale.
    "Blow it out your ass," I said. "You'd better hire yourself a hot attorney, babe, because you're going to need one."
    I moved off down the street, leaving Gwen behind.

Chapter 25
----
    I locked the door to my place and tried dialing Nikki out at the beach. The phone rang eight times and I hung up, pacing the room after that with an unsettled sensation in my chest. There was something off. There was something not right and I couldn't put my finger on what was bothering me. There was no feeling of closure. None. This should have been the end of it. The big climax. I'd been hired to find out who killed Laurence Fife and I had. The end. Finis. But I was left with half a case and a lot of loose ends. Gwen's killing of Laurence had been part premeditation and part impulse, but the rest of it didn't seem to fit. Why wasn't everything falling into place? I couldn't picture Gwen killing Libby Glass. Gwen had hated Laurence Fife for years, titillating herself perhaps with ways of killing him, maybe never even dreaming that she'd actually do it, never imagining that she could actually pull it off. She'd come up with oleander scheme and suddenly she'd seen a way to make it work. A perfect opportunity had presented itself and she'd acted. Surely Libby Glass's death couldn't have been that easy to arrange. How did Gwen know about her? How did she know where she lived? How could she have gotten into that apartment? And how could she have counted on her taking medication of any kind? I couldn't picture Gwen driving to Vegas either. Couldn't imagine her shooting Sharon in cold blood. For what? What was the point? Killing Laurence had wiped out an old grudge, satisfied an ancient and bitter hatred between them, but why kill the other two? Blackmail? Threat of exposure? That might account for Sharon but why Libby Glass? Gwen had seemed truly self-righteous in her bewilderment. Like her denial of any responsibility for killing the dog. There was just that odd note of genuine outrage in her voice. It didn't make sense.
    Unless there was someone else involved. Someone else who killed.
    I felt a chill.
    Oh my God. Lyle? Charlie? I sat down, blinking rapidly, hand across my mouth. I'd bought into the notion that one person killed all three, but maybe not. Maybe there was another possibility. I tried it out. Gwen had murdered Laurence Fife. Why couldn't someone else have spotted the opening and taken advantage of it? The timing was close, the method
