“It’s obvious they’re paper. What else would they be? Absorbent paper too. Don’t have a clue what the source is, though. Now, that dirt is very interesting. Can you get some more? Out of the cuffs?”

“I’ll try.”

Ben cut the stitching securing the cuff and unfolded it. He brushed more dirt out onto the card.

“’Scope it,” Rhyme ordered.

The zoologist prepared a slide and slipped it onto the stage of the compound microscope, which he again held rock steady for Rhyme, who peered into the eyepieces. “There’s a lot of clay. I mean, a lot. Feldspathic rock, probably granite. And—what’s that? Oh, peat moss.”

Impressed, Ben asked, “How d’you know all this?”

“I just do.” Rhyme didn’t have time to go into a discussion of how a criminalist must know as much about the physical world as he does about crime. He asked, “What else was in the cuffs? What’s that?” Nodding toward something resting on the subscription card. “That little whitish-green thing?”

“It’s from a plant,” Ben said. “But that’s not my expertise. I studied marine botany but it wasn’t my favorite subject. I’m more into life forms that’ve got a chance to get away when you’re collecting them. Seems more sporting.”

Rhyme ordered, “Describe it.”

Ben looked it over with a magnifying glass. “A reddish stalk and a dot of liquid on the end. It looks viscous. There’s a white, bell-shaped flower attached to it…. If I had to guess—”

“You do,” Rhyme snapped. “And quickly.”

“I’m pretty sure it’s from a sundew.”

“What the hell’s that? Sounds like dish soap.”

Ben said, “It’s like a Venus flytrap. They eat insects. They’re fascinating. When I was a kid we’d sit and watch ’em for hours. The way they eat is—”

“Fascinating,” Rhyme repeated sarcastically. “I’m not interested in their dining habits. Where’re they found? That’s what would be fascinating to me.”

“Oh, all over the place here.”

Rhyme scowled. “Useless. Shit. All right, run a sample of that dirt through the chromatograph after the cloth sample’s done.” He then looked at Garrett’s T-shirt, which was lying, spread open, on a table. “What’re those stains?”

There were several reddish blotches on the shirt. Ben studied them closely and shrugged, shook his head.

The criminalist’s thin lips curved into a wry smile. “You game to taste it?”

Without hesitation Ben lifted the shirt and licked a small portion of the stain.

Rhyme called, “Good man.”

Ben lifted an eyebrow. “I assumed that was standard procedure.”

“No way in hell would I have done that,” Rhyme responded.

“I don’t believe that for a minute,” Ben said. He licked it again. “Fruit juice, I’d guess. Can’t tell what flavor.”
