Cochraneâs at home, but sheâs not taking calls. This has been something of a shock to her.â
Cochrane nodded. âMe, too.â
âI suppose so. Of course.â
âWhatâs Washington doing in this? Why are you involved?â
âActually, itâs the Department of Homeland Security whoâs interested in your brotherâs murder. Iâm just a local field agent.â
âHomeland Security?â
âYour brotherâs office was ransacked, either just before or just after he was killed.â
âRansacked?â Cochrane knew he was making an ass of himself, but he couldnât think of anything else to say.
âDid your brother confide in you? Did he tell you anything about the work he was doing?â
âMikeâs a biologist, for chrissake! He wasnât involved in anything dangerous.â
âAre you certain of that?â
âHe worked with algae and cyanobacteriaââ
âCyanoâ¦?â
âCyanobacteria,â Cochrane repeated.
âThat sounds ominous.â
He didnât know whether to laugh or scowl at her ignorance. âTheyâre harmless bacteria that produce oxygen.â
âTheyâre not dangerous, then?â
Cochrane shook his head. âTheyâre on our side.â
Sandoval tilted her head slightly to one side, as if trying to determine if he was telling the truth. Cochrane realized she was very pretty, beautiful even.
âSomeone murdered your brother for a reason. I think it has something to do with his research.â
âMike said heâd hit on something that would make him rich, butââ
âSomething? What?â
âHe wouldnât tell me. Made me go out to Palo Alto to see for myself.â
âAnd?â she asked eagerly.
Cochrane felt his insides go hollow. âI never saw him. The receptionist wouldnât let me in. He was murdered while I was in the buildingâs lobby.â
She pursed her lips, disappointed. âSo you didnât get to see what he was working on.â
âNo. But you should be able to check it out on his computer.â
âThe laptop computer he worked on is missing. Stolen, we presume. His office was thoroughly looted of any paperwork that might have held his notes, his references, anything pertaining to his work.â
âWhat the hell were they after?â
âI was hoping you would know,â said Sandoval.
Cochrane didnât know what to say. Then his cell phone began playing Mozart. He pulled it out of his shirt pocket, flicked it open, and put it to his ear.
âHello.â
âPaul, itâs me.â He instantly recognized the voice of his brotherâs widow.
âIrene! Are you okay?â
âHeâs dead, Paul. Somebody killed Mike.â
Glancing at Sandoval, who turned away slightly and pointedly stared out the window, Cochrane said, âI know. I was there when it happened. I went to your house.â
âThe police told me. I should have phoned you earlier, Paul, but I couldnât. I just couldnât.â
He could hear the tears in her voice. âItâs okay, Irene. I was starting to worry about you, though.â
âIâm fine. Well, not really, but Iâm all right. I got home from the school and there were a pair of police detectives on the front steps. Thatâs how I found out.â
âI must have just missed you,â Cochrane said. Sandoval turned in her chair and studied the spines of the
Astrophysical Journals
on the top shelf of his bookcase.
âMy carpool dropped me off around five-thirty. We had a teachersâ meeting after classes.â
You donât need to give me an alibi, Cochrane thought. Aloud, he said, âLousy thing to come home to.â
Irene sighed heavily and Cochrane realized she must be struggling to hold herself together.
âIâll come out there tomorrow,â he said. âIâll help
