"Okay," said Nate, feeling as if he had just invited the Medusa in for a sandwich. "The Old Broad called."

"How is she?"

"Still nuts."

"How're you?"

"Getting there."

When a visitor first drives into the Hawaiian Islands Humpback Whale Sanctuary — five baby blue shiplap buildings trimmed out in cobalt, crouching on the edge of the huge Maalaea Bay and overlooking the ruins of an ancient saltwater fish pond — his first reaction is usually "Hey, not much of a sanctuary. You could get maybe three whales in those buildings, tops." Soon, however, he realizes that these buildings are simply the offices and visitor centers. The sanctuary itself covers the channels that run from Molokai to the Big Island of Hawaii, between Maui, Lanai, and Kahoolawe, as well as the north shores of Oahu and Kauai, in which there is plenty of room for a whole bunch of whales, which is why they are kept there.

There were about a hundred people milling around outside the lecture hall when Nate and Amy pulled into the parking lot in the pickup.

"Looks like a good turnout?" Amy said. She'd attended only one of the sanctuary's weekly lectures, and that one had been given by Gilbert Box, an ill-tempered biologist doing survey work under a grant for the International Whaling Commission, who droned through numbers and graphs until the ten people in attendance would have killed a whale themselves just to shut him up.

"It's about average for us. Behavior always draws more than survey. We're the sexy ones," Nate said with a grin.

Amy snorted. "Oh, yeah, you guys are the Mae Wests of the nerd world."

"We're action nerds," Nate said. "Adventure nerds. Nerds of romance."

"Nerds," Amy said.

Nate could see the skeletal Gilbert Box standing off to the side of the crowd under a straw hat whose brim was so wide it could have afforded shade for three additional people and behind a pair of enormous wraparound sunglasses suitable for welding or as a shield from nuclear flash. His gaunt face was still smeared with residue of the white zinc oxide he used for sun protection when out on the water. He wore a long-sleeved khaki shirt and trousers and leaned on a white sun umbrella that he was never seen without. It was a half hour before sunset, a warm breeze was coming off Maalaea Bay, and Gilbert Box looked like Death out for his after-dinner stroll before a busy night of e-mailing heart attacks and tumors to a few million lucky winners.

Nate had given Box the nickname "the Count," after the Sesame Street vampire with the obsessive-compulsive need to count things. (Nate had been too old for Sesame Street as a preschooler, but he'd watched it through grade ten while baby-sitting his younger brother, Sam.) People agreed that the Count was the perfect name for a survey guy with an aversion to water and sunlight, and the name had caught on even outside Nate and Clay's immediate sphere of influence.

Panic rattled up Nate's spine. "They're going to know we're faking it. The Count will call us on it the first time I say something that we don't have the data to back up."

"How's he going to know? You had the data a week ago. Besides, what's this 'we'? I'm just running the projector."

"Thanks."

"There's Tarwater," Amy said. "Who are those women he's talking to?"

"Probably just some whale huggers," Nate said, pretending that all of his mental faculties were required for him to squeeze the pickup into the four adjacent empty parking spaces. The women Tarwater was talking to were Margaret Painborne, Ph.D., and Elizabeth «Libby» Quinn, Ph.D. They worked together with a couple of very butch young women studying cow/calf behavior and social vocalizations. They were doing good work, Nate thought, even if it appeared to have a gender-based agenda. Margaret was in her late forties, short and round, with long gray hair that she kept perpetually tied back in a braid. Libby was almost a decade younger, long-legged and lean, blond hair going gray, cut short, and she had once, not too long ago, been Nathan Quinn's third wife. A second and totally different wave of anxiety swept over Quinn. This was the first time he'd encountered Libby since Amy joined the team.

"They don't look like whale huggers," Amy said. "They look like researchers."

"How is that?"

"They look like action nerds." Amy snorted again and crawled out of the truck.

"That's not very professional," Nate said, "that snorting-laugh thing you do." But Amy had already walked off toward the lecture hall, a carousel of slides under her arm.

Nate counted more than thirty researchers in the crowd as he walked up. And those were just the ones he was acquainted with. New people would be coming back and forth from the mainland all season — grad students, film crews, reporters, National Fisheries people, patrons — all hitchhiking on the very few research permits that were issued for the sanctuary.

For some reason Amy made a beeline for Cliff Hyland and his navy watchdog, Tarwater, who was out of uniform in Dockers and a Tommy Bahama shirt, but still out of place because his clothes were ironed to razor creases — his Topsiders had been spit-shined, and he stood as if there were a cold length of rebar wired to his spine.

"Hey, Amy," Cliff said. "Sorry to hear about the break-in. Bad?"

"We'll be all right," Amy said.

Nate strolled up behind Amy. "Hey, Cliff. Captain." He nodded to each.

"Sorry to hear about the break-in, Nate," Cliff said again. "Hope you guys didn't lose anything important."

"We're fucked," Nate said.

And Tarwater smiled — for the first time ever, Nate thought.

"We're fine." Amy grinned and brandished her carousel of slides like a talisman of power.

"I'm thinking about getting a job at Starbucks," Nate said.

"Hey, Cliff, what are you guys working on?" Amy asked, having somehow moved close enough into Cliff Hyland's personal space to have to look up at him with big, girly-blue eyes and the aspect of a fascinated child.

Nate cringed. It was… well, it was just not done. You didn't ask, not outright like that.

"Just some stuff for the navy," Cliff said, obviously wanting to back away from Amy, but knowing that if he did, somehow he'd lose face.

Nate watched while Amy grated his friend's middle-aged irrelevance against his male ego merely by stepping a foot closer. There, too, was a reaction from Tarwater, as the younger man seemed to be irritated by the fact that Amy was paying attention to Cliff. Or maybe he was just irritated with Amy because she was irritating. Sometimes Nate had to remind himself not to think like a biologist.

"You know, Cliff," Amy said, "I was looking at a map the other day — and I want you to brace yourself, because this may come as a shock — but there's no coastline in Iowa. I mean, doesn't that get in the way of studying marine mammals?"

"Sure, now you bring that up," Cliff said. "Where were you ten years ago when I accepted the position?"

"Middle school," Amy said. "What's in the big case on your boat? Sonar array? You guys doing another LFA study?"

Tarwater coughed.

"Amy," Nate interrupted, "we'd better get set up."

"Right," Amy said. "Nice seeing you guys."

She moved on. Nate grinned, just for a second. "Sorry, you know how it is?"

"Yeah." Cliff Hyland smiled. "We've got two grad students working with us this season."

"But we left our grommets at home, to analyze data," Tarwater added.

Nate and Cliff looked at each other like two old broken-toothed lions long driven from the pride — tired, but secure in the knowledge that if they teamed up, they could eat the younger male alive. Cliff shrugged, almost imperceptibly, that small gesture communicating, Sorry, Nate, I know he's an asshole, but what am I going to do? It's funding.
