“About three hundred and fifty grams of botulinum toxin is enough to kill everyone on the planet,” I reply. “Or about twelve ounces.”
“No fucking shit.”
“So it wouldn’t take much on the back of stamps to create a potent poison that would have caused a rapid onset of symptoms,” I add. “My guess is that within several hours Dawn Kincaid was feeling really bad. If Kathleen had used the stamps when she first received them, I wouldn’t have been able to interview her because she would have been dead.”
“Maybe that was the intention,” Benton says.
“I don’t know,” I reply. “But you have to wonder.”
“But that’s not what killed her, and that’s what’s weird.” Lucy hands out stacks of whatever she’s printed so far. “Someone sends her stamps spiked with botulinum toxin but doesn’t wait for her to use them. Why? Seems to me she would have used the stamps eventually, and when she did, she was going to die.”
“It might suggest that whoever sent them doesn’t work at the prison,” Benton remarks. “If you didn’t have access to Kathleen or what was in her cell or witness mail going out, you might assume the stamps were ineffective, not realizing she simply hadn’t gotten around to using them. So the person doing the tampering decided to try again.”
“The stamps sure as hell aren’t ineffective,” Marino comments. “And how would the poisoner know what’s effective?” Benton points out. “Who do you test your poisons on to make sure they work? Certainly not yourself.”
But you might test your poisons on inmates — a possibility I’ve considered throughout the evening — and that a warden might be inclined to allow it in certain cases, if she is driven by a need to control and punish, the way Tara Grimm seems to be. I remember the hard look in her eyes that wasn’t disguised by her southern charm when I sat in her office yesterday, and her obvious displeasure with the idea that a wrongfully convicted woman soon to be executed might go free or that a deal was in the works that could release Kathleen Lawler early. There could be no doubt that Tara resented Jaime Berger’s meddling in the lives of inmates and overriding the wishes of their respectable, highly praised warden, the daughter of another prominent warden, who designed the very facility that she considers rightfully hers.
It no longer seems possible Tara Grimm wasn’t aware of the kite Kathleen slipped to me. The warden probably knew all about it and not only didn’t care but considered my meeting with Jaime a gift, the ideal opportunity to have me intercepted by someone with a take-out bag that I suspect contained a potent dose of botulinum toxin serotype A injected into sushi or seaweed salad. Tara had known for almost two weeks that it was in the works for me to come to her facility, and somehow the woman with the take-out bag knew I was headed to Jaime’s apartment, and perhaps, as Lucy has suggested, this person was waiting in the nearby dark for me, possibly waiting all night and well into the morning, watching the silhouette of her victim walking past windows, waiting for lights to go off and back on, waiting for death.
People stalked and followed and spied on, and manipulated like puppets, by someone who is cunning and meticulous, a poisoner who is patient and precise and as cold as dry ice, and I can’t think of a more vulnerable population, a captive one like rats in a lab, especially if anyone working at the correctional facility is in collusion with whoever might be masterminding such sinister research. Figuring out what works and what doesn’t as you design a much bigger attack, biding your time, fine-tuning for months, for years.
Barrie Lou Rivers died suddenly while she was awaiting her execution. Rea Abernathy was found dead inside her cell, slumped over the toilet, and Shania Plames appeared to be a suicidal asphyxiation, supposedly hog-tying herself with her prison uniform pants. Then Kathleen Lawler, and Dawn Kincaid, and now Jaime Berger, all of the deaths disturbingly the same. Nothing is found on autopsy, the diagnosis one of exclusion. There was no reason, at least not in the earlier cases, to suspect homicidal poisonings that would elude routine toxicology screens.
It is almost two o’clock in the morning, and I don’t remember the last time I called General John Briggs at this hour. Whenever I’ve been as inconvenient as I’m about to be, I’ve had an ironclad reason. I’ve had proof. Lucy adds to my pile of printouts, and I take them with me. I go back to the bedroom and close the door as I imagine Briggs snapping up his cell phone wherever he’s sleeping or working. It could be the Air Force base in Dover, Delaware, the headquarters of the AFME and its port mortuary where our military casualties are flown in and given dignified transfers and sophisticated forensic examinations, including three-dimensional CT and explosive-ordnance scans. He could be in Pakistan or Afghanistan or Africa, maybe not the MIR space station, but we speculate about it, not really joking, because AFMEs could end up any place where deaths are the jurisdiction of the federal government. What Briggs doesn’t need is one more thing to worry him needlessly. He doesn’t need me and my intuition.
“John Briggs,” his deep voice answers in my wireless earpiece. “It’s Kay,” and I tell him why I’m calling.
“Based on what?” he says what I knew he would.
“Do you want the short answer or a more involved one?” I prop pillows behind me on the bed and continue scanning the information Lucy has been printing out.
“I’m about to get on a plane in Kabul, but I have a few minutes. Then you’re not going to get me for about twenty-five hours. Short answers are my favorite, but go ahead.”
I give him the case histories, starting with suspicious deaths at the GPFW that Colin has told me about, and from there I move on to what has happened in the past twenty-four hours. I point out the obvious concern that the one confirmed poisoning by botulinum toxin serotype A, Dawn Kincaid, suggests an enhanced delivery system, something we’ve not seen before.
“While it’s theoretically possible that death or severe illness due to botulinun toxin can occur in as few as two to six hours,” I explain, “usually it’s more like twelve or twenty-four. It can take longer than a week.”
“Because the cases we’re accustomed to seeing are foodborne,” Briggs says, as I go through the printouts Lucy generated, studying an enhanced surveillance image of the woman who delivered the take-out bag of sushi last night.
A sadist, a poisoner, I believe.
“We don’t see cases of exposure to the pure toxin,” Briggs says. “I can’t think of a single one.”
The woman’s head and neck are completely whited out, but Lucy has produced sharply defined and enlarged images of the rest of her, including the silvery bicycle she walked across the street and leaned against the lamppost. She is in dark pants, running shoes and socks, no belt, and a light-colored short-sleeved blouse tucked in. The only flesh exposed is her forearms and her hands, and a close-up of her left ring finger shows a baguette-cut square band that might be white gold or yellow or platinum, I can’t tell. All of the images are infrared and in shades of white and gray.
“Food contaminated by the Clostridium botulinum spores that produce the toxin,” Briggs is saying, “and it’s got to work its way through the digestive tract, usually becoming absorbed in the small intestine before it gets into the bloodstream and begins attacking neuromuscular proteins, basically attacking the brain and preventing the release of neurotransmitters.”
The woman in the surveillance footage also has on a watch: what Lucy shows through other image files is a dark-faced Marathon wristwatch with a high-impact fibershell and waterproof and dustproof case, made by contract with the U.S. and Canadian governments for issuance to military personnel.
