K Is for Killer

the cause of death was undetermined, which means the coroner's office couldn't say with any certainty what she died of, right?"
    Reluctantly. "That's right."
    "How do you know she didn't have an aneurysm or a stroke or a heart attack? With all the allergies she suffered, she might have died from anaphylactic shock. I'm not saying you're wrong, but you're making a big leap here without a shred of proof."
    "I understand. I guess it sounds crazy to you, but I know what I know. She was murdered. I'm absolutely sure of it, but I can't get anyone to listen, and what am I supposed to do? I'll tell you something else. She had quite a lot of money at the time she died."
    "I low much?"
    "Close to five hundred thousand dollars' worth of stocks and bonds. She had some money in CDs, but the bulk was in securities. She had five or six different savings accounts, too. Now where'd she get that?"
    "How do you think she acquired it?"
    "Maybe somebody paid her off. To keep quiet about something."
    I studied the woman, trying to assess her powers of reasoning. First, she claimed her daughter was being blackmailed or coerced. Now she was suggesting she was guilty of extortion. I set the issue aside temporarily and shifted my focus. "How did the police react to the tape?"
    Dead silence.
    I said, "Janice?"
    Her expression was stubborn. "I didn't take it to them. I wouldn't even show it to Mace, because he'd die of embarrassment. Lorna was his angel. He'd never be the same if he knew what she'd done." She picked up the tape and put it back in the paper bag, folding the top down protectively.
    "But why not show it to the cops? At least it would give them a fresh avenue..."
    She was already shaking her head. "No, ma'am. No way. I'd never in this world turn it over to them. I know better. That's the last we'd ever see of it. I know it sounds paranoid, but I've heard of cases like this. Evidence they don't like disappears into thin air. Get to court and it's mysteriously vanished. Period, end of paragraph. I don't trust police. That's the point."
    "Why trust me? How do you know I'm not in cahoots with them?"
    "I have to trust someone. I want to know how she got into this... blue movie stuff... if it's why she was killed. But I'm not trained. I can't go back in time and figure out what happened. I have no way to do that." She took a deep breath and changed gears. "Anyway, I decided if I hired an investigator, that's the person I'd give the tape to. I guess now I have to ask if you're willing to help, because if you're not, I'll have to find someone else."
    I thought about it briefly. Of course I was interested. I just wasn't sure about my chances of success. "An investigation like this is likely to be expensive. Are you prepared for that?"
    "I wouldn't have come up if I wasn't."
    "And your husband's in agreement?"
    "He's not wild about the idea, but he can see I'm determined."
    "All right. Let me nose around first before we sign any contracts. I want to make sure I can do you some good. Otherwise, it's a waste of my time and your money."
    "Are you going to talk to the police?"
    "I'll have to do that," I said. "Maybe unofficially at first. The point is, I need information, and if we can get their cooperation, it will save you some bucks."
    "I understand that," she said, "but you have to understand one thing, too. I know you feel the police here are competent, and I'm sure that's true, but everybody makes an occasional mistake, and it's just human nature to want to cover it up. I don't want you to decide whether or not you can help on the basis of their attitude. They probably think I'm crazy as a loon."
    "Believe me, I'm capable of making up my own mind about things." I could feel a crick in my neck, and I took a look at my watch. Time to wind it up, I thought. I asked for her home address, her home phone, and the number at the coffee shop, making notes on my legal pad. "Let me see what I can find out," I said. "In the meantime, can you leave that with me? I'd like to get myself up to speed. The meter won't actually start ticking until we have a signed contract."
    She glanced down at the paper sack beside her but made no move to lift it. "I guess so. I suppose. I wouldn't want anybody else to get their hands on the tape. It'd kill Mace and the girls if they knew what was in here."
    I crossed my heart and held my hand up. "I'll guard it with my life," I said. I didn't think there was any point in reminding her that pornography is a commercial
