found himself wondering again why a federal agent should be interested in Mike.
Before he could ask her, though, she had parked in the driveway and popped the carâs trunk. Cochrane got out and went to the back of the car. By the time he had pulled out his roll-on suitcase and slung his laptop over his shoulder, Sandoval was already through the lobbyâs glass doors, a single shapeless tote bag in one hand. He slammed the trunk shut.
As he came up to the registration desk, Sandoval said smilingly, âI know a neat little sushi place not far from here. Interested?â
âSure,â he replied automatically.
âOkay. Give me half an hour to unpack and shower. Iâll meet you right here.â
Cochrane was impressed with his mini-suite. It included a kitchen, a sofa, high-speed Internet access, and even a gas-fed fireplace. The government must be paying for this, he thought. Nobody had asked to see his credit card. He set up his laptop on the coffee table, checked his sparse e-mail, and still was back down in the lobby before Sandoval.
She came out of the elevator dressed in a comfortable pair of off-white slacks and a loose rose-pink blouse with a modest collared neckline. Still she looked elegantly attractive. Cochrane couldnât help smiling as they walked together out to the parking lot.
The sushi bar was noisy with customersâ laughter and conversation and the Japanese chefs yelling back and forth to one another. A busy place, Cochrane saw. Country music, of all things, wailing out of the ceiling speakers. The spicy tang of ginger and other aromas in the air. Three TV sets, all muted and tuned to sports shows. Locals crowded the bar, so he and Sandoval took a small table off in the shadows. Cloth napkins, he noticed. He began to polish his eyeglasses as a waitress took their order for hot sake.
âSo what exactly was your brother working on?â she asked, after a first sip from the tiny ceramic cup.
âDamned if I know,â he said, raising his voice enough to be heard over the noise. âHe was going to show me but I got there too late.â
Sandoval sipped at her sake, then said, âNo, I mean in general. You said he was some sort of biologist.â
âMicrobiology. He dealt with algae and bacteria.â
âCyanobacteria.â
âYou remembered.â
âWhatâs so special about them?â
The kimono-clad blond waitress brought their trays. Cochrane realized he was hungry and picked up his chopsticks.
âCyanobacteria?â Sandoval prompted.
âIâm not a biologist,â Cochrane muttered as he fumbled his first try at snaring a piece of eel roll.
She gave him that dimpled smile again. âYouâre a scientist. You know more about this kind of thing than I do.â
Finally stuffing the rice-wrapped piece of eel into his mouth, Cochrane chewed fast, swallowed hard, then answered, âCyanobacteria are very ancient forms of life. Billions of years old. If I remember correctly, they were one of the first organisms to use chlorophyll.â
âLike green plants.â
âRight. But cyanobacteria are one-celled creatures. Bacteria.â
âYour brother was working with them?â
âFarâs I know. Yes.â
She picked up a piece of sushi expertly, then took another sip of sake.
âYou said that these bugs produce oxygen?â she asked.
Cochrane pushed his glasses back up his nose. âThey changed the earthâs atmosphere. Several billion years ago this planetâs atmosphere was mostly carbon dioxide. Unbreathable. But cyanobacteria and other chlorophyll-bearing organisms put out so much oxygen that our atmosphere eventually changed to what we have now: oxygen and nitrogen.â
âThereâs still carbon dioxide in the atmosphere, isnât there? Isnât that what causes the greenhouse effect?â
Cochrane started talking about carbon dioxide and greenhouse warming and
