“Now it's just you and me,” she said. “I'm going to ask you a couple of questions, and I'm only going to ask them once. If I think you're lying to me, I'll have my dog clamp down on your windpipe until you turn blue. And I know when a man is lying to me, Tullyâso either you'd better be the world's best liar or you'd better tell me the truth. Got it?”
Tully did his best to nod.
“Did you put those bugs in Kathryn's field?”
“No.”
“Do you know who did?”
“No.”
“Did you have anything at all to do with her husband's death?”
“Of course not.”
Alena studied his eyes for a moment, then slowly nodded. “Well, what do you know? You're not a complete jerk after all.”
“Call off your dog,” Tully said.
“In a minute. First I'm going to walk over to that truck of yours and see if you've got a gun rack or a revolver in the glove compartment, 'cause you're just the kind of big baby who might come back over here and shoot a girl.”
She did. The truck was clean.
“Satisfied?” he asked.
“Almostâjust a couple of final things we need to cover.” She bent down close to his ear and lowered her voice to a whisper. “You're not getting this farm,” she said. “Not now, not ever. She'll salt the fields and burn the house down before she sells it to youâI'll make sure of it. Never, ever offer to buy this place againâit hurts her feelings, and I don't like to see her hurt. And one more thing, Tully: If I ever hear you call that beautiful little girl âtwisted' again, I won't need a dogâI'll tear your throat out myself.”
Dr. Polchak?”

ick looked up from his microscope. He saw two figures standing in his doorwayâa tall, heavy man with coarse black hair and a woman of similar age but much smaller in stature. They were both dressed professionally.
The man pointed to the woman with his thumb. “She said we should make an appointment first, but I told her we'd have better luck if we just dropped by. We never agree on things like that.”
“I don't do marriage counseling,” Nick said.
The woman smiled. “We're not married, Dr. Polchak. If he wasn't my partner I would have shot him a long time ago.”
“Sounds like a marriage to me.”
“I'm Special Agent Califano,” she said. “This is my partner, Special Agent Waleski. We're with the Drug Enforcement Administration.”
“The DEA. You got my sample then.”
“That's why we're here.”
“And?”
The woman paused. “You want us to shout it from the doorway?”
“No need to shout. I can hear you.”
“How 'bout we come in?” Waleski suggested. “That way we can all get to know each other better.”
“Right. Sorry. Come on in.”
The two DEA agents entered the laboratory and looked at the tables jammed with specimen cases, laboratory equipment, and electronic gear.
“Look at this place,” Waleski said.
Nick shrugged. “It's not much, but I call it home.”
“Do you actually know how all this stuff works?”
“The only thing that works is the butterfly netâthe rest is just to impress people.”
Waleski looked at him. “No kidding?”
Califano elbowed her partner in the gut. “He's being sarcastic, dummy.”
Waleski extended his finger toward a large red button on a formidablelooking apparatus. “What does this button do?”
“It sends ten thousand volts of electricity surging up your arm.”
“I'll bet it doesn't.”
“I wish it did. If âDiscovery Time' is over, can we get down to business?”
“Sure. Can we sit down?”
“It's a lab. There is no place to sit down.”
“You work standing up?”
“I stand up all day and I lie down all night. Do DEA agents do it differently?”
“What about visitors?”
“If I'm lucky they feel unwelcome and leave. What about my sample?”
They gathered around an empty lab table. The edge of the table barely rose past Waleski's waist but covered half of Califano's torso, making her look even smaller than she did in the doorway. Waleski swung his briefcase onto the table and took out a multipage report.
“This came in this morning. It's from our Special Testing and Research Lab up in Dulles, Virginia.”
“I wasn't expecting a personal visit,” Nick said. “They could have just mailed it.”
“They mailed it to us. They asked us to deliver it personally.”
“Then I assume they found something.”
“You sent the DEA an ordinary sample of cannabis, Dr. Polchak. Do you mind if I ask why?”
“Because it wasn't ordinary.”
“What do you mean?”
“Well, first of all, the marijuana originated in Colombia.”
Waleski glanced down at the report. “I was just about to tell you thatâRed Colombian Haze, they call it. How did you know?”
“Insect parts.”
“Insect parts?”
“Legs, heads, antennae, maggotsâyou always find insect parts in a marijuana shipment, just like you do in food.”
“In food?”
“Of course. Ninety-five percent of all the animal species on earth are insects. Many of them like the same food you do. It's impossible to keep insect parts out of food; the FDA just limits their number. Take canned orange juice, for example: An eight-ounce glass is allowed to have up to five fly eggs or one maggot.”
“So much for Happy Meals,” Waleski groaned.
“Or take chocolate for exampleâ”
Califano held up her hand. “Stop! Don't make me use my gun. Can we get back to the cannabis, please?”
Nick nodded. “I've been going through the sample I collected, and I've been able to identify body fragments from a beetle that's indigenous to Colombia. That means the shipment must have originated there.”
“That's not exactly unusual,” Waleski said. “The Colombians grow a lot of the stuff.”
“There's something else. The cannabis contained an extremely large number of insect eggs.
Manduca sexta,
to be specificâa type of hornworm.”
“Is there anything particularly unusual about that insect?”
“Yes, there is.”
“What?”
“Nothing.”
Waleski blinked. “You want to run that by me again?”
“The unusual thing about
Manduca sexta
is that it's one of the most ordinary insects of all. The larva is enormous. It has a very accessible nervous system and its organs are easy to isolate and dissectâthat makes it a model organism for research. Entomologists call it âthe white lab rat of insects.'”
“Fascinating. So what?”
“
The white lab rat of insects
âthe perfect insect to choose if you wanted to conduct an experiment.”
“What kind of experiment?”
“To see if living insects could survive shipment in marijuana.”
The DEA agents looked at each other.
“Hiding insects in drugs?” Califano said. “That's kind of an expensive shipping method, don't you think? I thought FedEx was priceyâwhy would anybody want to do that?”
“I don't know whyâbut I think someone did.”
“How do you know?”
“
Manduca sexta
is a North American insectâyou don't find it in Colombia. So how does a North American insect find its way into a drug shipment that originated in Colombia? It doesn'tâunless someone purposely puts it there. And the hornworm only feeds on plants from the
Solanaceae
familyâpotatoes, tomatoes, tobaccoânever on marijuana.”
“Did you say tobacco?”
“Yes.
Manduca sexta
is the tobacco hornworm. Why?”
Waleski opened the report. “Yeah, here it isâI thought I remembered that. The cannabis you sent us also contained tobacco leaves, shredded up along with the marijuana.”
“Let me see that.” Nick grabbed the report and studied the chart showing the chemical analysis of the marijuana.
Califano shrugged. “Maybe it's just fillerâsomebody trying to make a few extra bucks.”
Nick shook his head. “I don't think so. There's all kinds of stuff that shouldn't be in there: sugar, yeast, caseinâ”
“What's âcasein'?”
“A common proteinâyou find it in milk and cheese. Look at this: There's even some wheat germ.”
Califano smiled. “What do you know? The potheads are getting healthy.”
“So what do you make of all this, Doc?”
Nick looked at him. “Why are you here, Waleski? You two didn't come over here just to hand-deliver a reportâand the DEA wouldn't get excited over one bizarre marijuana sample.”
“It's not just one,” Waleski said.
“Excuse me?”
“In the last month we've intercepted two other marijuana shipments exactly like the one you sent usâone in Iowa and one in Illinois.”
“Were the same insect eggs present?”
“Yeahâbut we didn't know what they were until now.”
“Did they rear any of them? Did they let the eggs hatch and raise them to adults?”
“I don't think so. They just took specimens and preserved them. I can request samples for you if you want them.”
“No needâI already know what they are. I wanted them alive.”
“Why?”
“Come here. Let me show you something.” Nick led both agents to the microscope and let each one peer through the powerful lens.
“What am I looking at?” Califano asked.
“A tobacco hornworm. That little thing growing from the back of its head is a parasite of some sort. The insect is dead, but the parasite is still growing.”
“I see it. What is it?”
“I have no ideaâbut I'm fairly certain the parasite was present on the eggs when they were shipped. That's why I wish your people had reared those other eggsâI'd like to know if they were infected with the same parasite.”
Waleski took his turn at the microscope. “Yeah, I see it too. Is this something you don't see very often?”
“Some insects are commonly parasitizedânot this insect.”
“Is that a big deal?”
“It might be. I don't know yet.”
Waleski looked up. “Look, Dr. Polchak, we've been instructed to ask you a couple of questions.”
“Go ahead.”
“Where did you find your sample?”
“Not far from hereâon a farm in Sampson County. I'm investigating a murder there.”
“A murder?”
“A farmer named Michael Severenson was shot in his own tomato field. That's where I found the marijuana, right there in the dirtâsomebody had thrown it out. Quite a coincidence, don't you think? Marijuana just happens to get tossed into a tomato field; the marijuana just happens to contain tobacco hornworm eggs; tobacco hornworms just happen to love tomato fields. Isn't coincidence amazing?”
“Then you think it was done on purpose.”
“Yes, I do.”
“Why?”
“I don't know yet.”
“Any idea where the drugs came from?”
“I'm hoping you guys can help with that. That's what you do, isn't it?”
“That's part of it.”
“So that's why you're hereâbecause my sample matched two others you found, and you think the same guy might've sent all three.”
“It looks that way to us. We look for similarities, Dr. Polchakâsimilar ingredients, similar packaging, similar method of transport. That's how we track down suppliers.”
“Well, let me know if you find this one. I'd like to know what he's up to.”
“It's an interesting theory you've got there, Dr. Polchak, but there's one thing you haven't explained.”
“What's that?”
“Why would anyone want to smuggle insects in marijuana?”
“I don't know,” Nick said, “but I have a feeling we'd better find out.”

ick leaned into the door with his shoulder and pushed; a cascading stack of journals and books occupied both of his hands. The door slowly gave way under his weight and he stepped out of Gardner Hall and into the afternoon sunshine. He felt the last breath of airconditioning on his back, then the suffocating August heat. The heat felt almost comforting after a day in his chilly laboratory, but he knew the fuzzy feeling would last only about ten more secondsâthen his eyeglasses would begin to fog over and his shirt would cling to his back and he would begin to curse the first misguided settlers of North Carolina.
