Free River of Ruin by Jack du Brul Page A

talking about?” she asked in her scratchy alto voice.
    “I noticed something was wrong when we first arrived on this river. There were no sounds from the jungle, no birds or monkeys. An area like this should sound like a zoo at feeding time. I also saw that a lot of the trees were stripped of foliage on their upstream side, as if a storm had passed through.”
    “I noted that stuff too.” Captain Vanik nodded. “I didn’t think anything of it.”
    “Neither did I until I did some exploring. Some of the dead chickens supposedly shot by the gunmen hadn’t been shot at all. They didn’t miss the goats or dogs but they just raked the chicken pen figuring no one would look too closely. And the animal corpses I saw in the jungle show no physical trauma, no reason to be dead. Also they weren’t decomposed yet. Few insects out there to eat them. That’s when I checked around the kitchen tent. The cockroaches were all dead and all of them were on their backs.”
    “Meaning?”
    “Cockroaches breath through a tube on their abdomens. When they’re poisoned, they roll over in an effort to get more air. An exterminator explained it to me when I first bought my town house and discovered a roach problem. The only thing that could have killed the roaches, the birds, monkeys and Gary’s people at the same time is some kind of poison gas. With me so far?”
    “Yeah. I can see that.”
    “Okay, if it was an attack by rebels using mortars or gas grenades, the people would have panicked and tried to run into the jungle. Yet everyone appears to have simply fallen dead where they were. No one ran anywhere. No one panicked. They all just fell dead when the carbon dioxide hit.”
    “How do you know it was CO 2 ?”
    “Because it’s colorless, odorless, heavier than air, and can come from a natural source. It would have swept this camp like a wind that no one would have thought anything of until they started to die.” He paused. “And because something like this has happened before.”
    Lauren’s bicolored eyes told him to continue. “In August of 1986 a volcanic lake called Nyos in Cameroon, Africa, erupted one night, belching out thousands of tons of CO 2 that killed about seventeen hundred people. The gas had risen up from a magma chamber under the lake and became dissolved in the water until something released it, a small earthquake possibly. Like opening a can of soda after shaking it, the gas came out of solution in a fountain that scientists estimate was two hundred and fifty feet tall. The villagers lived in a valley below the lake. When the heavy gas poured into the town, it suffocated every living creature.”
    She listened intently. “I’ve never heard of such a thing.”
    “Few people have. There’s only one other lake like it in the world, well, maybe two if I’m right about what happened here.”
    “I’m not saying I don’t believe you, but volcanic gas can’t explain bullet holes. And you said this wasn’t Colombians. Why?”
    “This is where the story gets really weird.” He told her about Gary’s belief in the Twice-Stolen Treasure and how he thought it might be here. Then he explained how he’d been drawn into the search by going to a Paris auction and how thieves almost made off with the Lepinay journal, saying that it was the only item not purchased by a nameless Chinese businessman with ties to Panama.
    “So you’re saying some Chinese guy who’s looking for this treasure shot a bunch of corpses for the fun of it?”
    “I think what happened was he came out here to hijack Gary’s effort, I assume by killing him and his people, but when he arrived he found everyone was already dead. He had to know that eventually Gary’s wife would become suspicious and the bodies would be found. He couldn’t afford to have such a mysterious death investigated. Scientists would fly in from all over the world to test the lake to see if it was a CO 2 eruption.”
    “By shooting the bodies,” Lauren
