“A Coke?”
“I don’t believe so. We want to know where this woman was held captive and where she was killed. We’re hoping this bug has some specialized habitat, or it’s limited in range, you know, or it only sleeps on some kind of tree—we want to know where this insect is from. I’m asking for your confidence because—if the perpetrator put the insect there deliberately—then only he would know that fact and we could use it to eliminate false confessions and save time. He’s killed six at least. Time’s eating us up.”
“Do you think he’s holding another woman right this minute, while we’re looking at his bug?” Roden asked in her face. His eyes were wide and his mouth open. She could see into his mouth, and she flashed for a second on something else.
“I don’t know.” A little shrill, that. “I don’t know,” she said again, to take the edge off it. “He’ll do it again as soon as he can.”
“So we’ll do this as soon as we can,” Pilcher said. “Don’t worry, we’re good at this. You couldn’t be in better hands.” He removed the brown object from the jar with a slender forceps and placed it on a sheet of white paper beneath the light. He swung a magnifying glass on a flexible arm over it.
The insect was long and it looked like a mummy. It was sheathed in a semitransparent cover that followed its general outlines like a sarcophagus. The appendages were bound so tightly against the body, they might have been carved in low relief. The little face looked wise.
“In the first place, it’s not anything that would normally infest a body outdoors, and it wouldn’t be in the water except by accident,” Pilcher said. “I don’t know how familiar you are with insects or how much you want to hear.”
“Let’s say I don’t know diddly. I want you to tell me the whole thing.”
“Okay, this is a pupa, an immature insect, in a chrysalis—that’s the cocoon that holds it while it transforms itself from a larva into an adult,” Pilcher said.
“Obtect pupa, Pilch?” Roden wrinkled his nose to hold his glasses up.
“Yeah, I think so. You want to pull down Chu on the immature insects? Okay, this is the pupal stage of a large insect. Most of the more advanced insects have a pupal stage. A lot of them spend the winter this way.”
“Book or look, Pilch?” Roden said.
“I’ll look.” Pilcher moved the specimen to the stage of a microscope and hunched over it with a dental probe in his hand. “Here we go: No distinct respiratory organs on the dorsocephalic region, spiracles on the mesothorax and some abdominals, let’s start with that.”
“Ummhumm,” Roden said, turning pages in a small manual. “Functional mandibles?”
“Nope.”
“Paired galeae of maxillae on the ventro meson?”
“Yep, yep.”
“Where are the antennae?”
“Adjacent to the mesal margin of the wings. Two pairs of wings, the inside pair are completely covered up. Only the bottom three abdominal segments are free. Little pointy cremaster—I’d say Lepidoptera.”
“That’s what it says here,” Roden said.
“It’s the family that includes the butterflies and moths. Covers a lot of territory,” Pilcher said.
“It’s gonna be tough if the wings are soaked. I’ll pull the references,” Roden said. “I guess there’s no way I can keep you from talking about me while I’m gone.”
“I guess not,” Pilcher said. “Roden’s all right,” he told Starling as soon as Roden left the room.
“I’m sure he is.”
“Are you now.” Pilcher seemed amused. “We were undergraduates together, working and glomming any kind of fellowship we could. He got one where he had to sit down in a coal mine waiting for proton decay. He just stayed in the dark too long. He’s all right. Just don’t mention proton decay.”
“I’ll try to talk around it.”
Pilcher turned away from the bright light. “It’s a big family, Lepidoptera. Maybe thirty thousand butterflies and a hundred thirty thousand moths. I’d like to take it out of the chrysalis—I’ll have to if we’re going to narrow it down.”
“Okay. Can you do it in one piece?”
“I think so. See, this one had started out on its own power before it died. It had started an irregular fracture in the chrysalis right here. This may take a little while.”
Pilcher spread the natural split in the case and eased the insect out. The bunched wings were soaked. Spreading them was like working with a wet, wadded facial tissue. No pattern was visible.
