voice said, âHello, Deputy Calhoun. This is Ella Grimshaw calling you on Thursday morning from the medical examinerâs office here in Augusta. When I saw you yesterday, I promised Iâd let you know when I heard from the CDC. Their report just came in a short time ago, and Iâm relieved to tell you that those two victims from St. Cecelia, who we determined were not killed by gunshot wounds, appear not to have died from some rare mutated virus or some insidious new strain of influenza, either. I donât know if youâre interested in the details, but they are public record, and Iâd be happy to share them with you if you want. You may call me here at the office or on my cell phone.â She recited two numbers, and Calhoun knew heâd remember them without writing them down.
He tried Dr. Grimshawâs office number and reached a receptionist, who asked his name and put him through.
A moment later Dr. Grimshaw said, âDeputy Calhoun. Hello.â
âHi,â he said. âIâm returning your call.â
âRight,â she said. âI told you Iâd call when I had something new about the McNulty and Gautier deaths, right?â
âYes, maâam.â
âWell, I got the report from the CDC just this morning,â she said. âThey both died of botulism poisoning.â
âBotulism,â said Calhoun.
âThatâs right.â
âI donât know anything about botulism,â he said. âItâs pretty deadly, isnât it?â
âVery deadly,â she said. âFortunately, itâs quite rare. We have only about a hundred and fifty cases a year in the United States. The botulinum neurotoxins kill you by paralyzing your respiratory system. Not a pleasant way to die. Itâs actually the most poisonous substance known to man.â She hesitated, then said, âItâs no wonder that we worry about terrorists.â
âYou saying that stuffâs a biological weapon?â He remembered how Mr. Brescia had told him that he thought McNulty was working on something involving national security when he died. A biological weapon in the hands of terrorists would certainly qualify.
âNot a weapon,â she said. âNot as far as we know. Not yet, anyway. We worry that it could be, though. Just a matter of figuring out how to package it and deliver it efficiently.â
âSo how did McNulty and Millie Gautier get botulism? Not from terrorists, I assume.â
âNo,â said Dr. Grimshaw. âThere have been no terrorist incidents lately in Aroostook County.â Dr. Grimshaw chuckled softly. âNo, so far this is good news. Most likely they both just ate the same tainted food. They apparently died at about the same time.â
âThatâs good news, huh?â
âIf no one else ate that food, if itâs not an outbreak, itâs good news, yes.â
âHow long between when you eat the bad food and when you die?â
âIt can be as little as six hours or as much as several days,â she said. âWhy do you ask?â
âJust wondering,â he said, though since he intended to investigate McNultyâs and Millie Gautierâs deaths, he was thinking that the information could prove helpful. âHow do you figure it?â he said. âThey were driving in their car, and both of them started to feel sick, so they pulled off the road there where they happened to be, which was in the woods on the outskirts of St. Cecelia, and they sat there in their car until they were dead? Then somebody came along and shot them both and tried to make it look like a murder and a suicide?â
âI guess so, Mr. Calhoun,â said the doctor. âItâs a hard one to figure, isnât it? Frankly, right now Iâm more concerned with the health of the people living in and around the town of St. Cecelia than I am with the details of these two deaths. With
