I Is for Innocent

for sport. Guy like Morley whose liver or kidney functions were probably already hampered by disease will be more severely affected by any kind of toxic agent because they got no efficient way to excrete such a substance and they probably can't tolerate as much as a healthy individual. Few things we can probably eliminate right off the bat," he said. "Acids, alkalies. I take it she didn't mention any kind of smell to his breath."
    "No, and she'd have noticed. They tried mouth-to-mouth resuscitation at first and then figured out it was pointless."
    "Takes out cyanide, paraldehyde, ether, disulfide, and nicotine sulfate. You couldn't palm those off on a person anyway."
    "Arsenic?"
    "Well, yeah. Symptoms you described would fit that pretty well.
    Except him feeling better. I don't like that much. Too bad he never went over to ER. They'd have tagged it."
    "I guess with his wife sick, he didn't want to be a bother," I said. "Everybody's had the flu. He probably thought that's all it was."
    "Which it might have been," Burt said. "On the other hand, if it's something he ate and you're talking about the gastrointestinal tract as the portal of entry, then you're talking about a period of time here when you got both chemical transformation and elimination. Generally speaking, chemicals that enter a living organism are either metabolized, eliminated, or both, which means you're progressively reducing the amount of detectable poison. Digestive system goes to work. Hell, he's throwing up the evidence. If the poison kills quickly, there's almost always quantities present on autopsy. It doesn't help he's been embalmed. In a situation like that, when you've got embalming fluid injected in the circulatory system with resultant visceral profusion, toxicologist's problems are blown way bad."
    "But would it still be possible to identify?"
    "Probably. We'd have to analyze samples of clean embalming fluids, too, check those against whatever foreign elements and compounds are found in the viscera. I tell you what would be the biggest help if you want to get serious about this: Bring me any household products you can find on the premises. Check the garbage for suspect foods. Pill bottles, rat poison, roach powder, cleaning and disinfecting agents, garden insecticides, that kind of thing. I can have a conversation with the funeral director and see if he has anything to contribute. Those guys are pretty sharp once they know what you're after."
    "So you'll do it?"
    "Well, if she signs the papers, we'll give it a shot."
    I could feel excitement bubble up, mixed with equal parts fear. If I was wrong, I was going to feel like a fool.
    "What's the grin for?" he asked.
    "I didn't think you'd take me seriously."
    "I'm paid to take people seriously when it comes right down to it. Lot of times, presumption of death by poisoning only comes about because of suspicion on the part of decedent's friends and relatives. We'll bring Morley out here and take a look."
    "What about the funeral?"
    "They can go ahead with the services. We'll have him brought out here after that and get right on it." He paused, giving me a speculative look. "Got a suspect in mind if it turns out you're right?"
    "I literally don't have a clue," I said. "I'm still trying to figure out who killed Isabelle Barney."
    "I wouldn't try too hard if I were you."
    "How come?"
    "That kind of curiosity might have been what killed Morley."

Chapter 16
----
    I couldn't believe I had to go back to Morley's again, but that's where I was headed. Burt Walker had asked me to bring him any household products that were possible poison candidates. Louise was out in front, standing at the mailbox, when I pulled up. If she was surprised to see me she gave no indication. She waited patiently while I parked the car and got out. We began walking toward the house as companionable as old friends.
    "Where's Dorothy?" I asked.
    "She's gone to her room to rest."
    "Was she upset?"
    Her look was frank. "My sister is a realist. Morley's gone. If someone poisoned him, she wants to know. Of course it's upsetting. Why wouldn't it be?"
    "I hated to add to her burden, but I didn't see a way around it."
    "There's nothing either one of us can do about that. What brings you back?"
    I told her about my conversation with the coroner. "He doesn't seem optimistic, but at least he's willing to check into it if I round up some possibilities. I'm going to need some sort of carrier for the items we find."
    "How about a kitchen
