"Why no autopsy?" Rachel broke in.

"Because I think he was murdered."

"I thought you said he died in his office."

"He did."

"You think he was murdered at work? Workplace violence?"

She still didn't get it. "I mean premeditated murder. Carefully thought out, expertly executed murder." "But…why would someone murder Andrew Fielding? He was an old man, wasn't he?"

"He was sixty-three." Recalling Fielding's body on the office floor, mouth agape, sightless eyes staring at the ceiling, I felt a sudden compulsion to tell Rachel everything. But one glance at the window killed the urge. A parabolic microphone could be trained on the glass.

"I can't say anything beyond that. I'm sorry. You should go, Rachel."

She took two steps toward me, her face set with purpose. "I'm not going anywhere yet. Look, if anyone died while not under a doctor's supervision in this state, there has to be an autopsy. And especially in cases of possible foul play. It's required by law."

I laughed at her naiveté. "There won't be an autopsy. Not a public one, anyway."

"David-"

"I really can't say more. I shouldn't have said that much. I just wanted you to know… that it's real."

"Why can't you say more?" She held up a small, graceful hand. "No, let me answer that. Because to tell me more would put me in danger. Right?"

"Yes."

She rolled her eyes. "David, from the beginning you've made extraordinary demands about secrecy. And I've complied. I've told colleagues that the hours you spend in my office are research for your second book, rather than what they really are."

"And you know I appreciate that. But if I'm right about Fielding, anything I tell you now could put your life at risk. Can't you understand that?"

"No. I've never understood. What sort of work could possibly be so dangerous?"

I shook my head.

"This is like a bad joke." She laughed strangely. "'I could tell you, but then I'd have to kill you.' It's classic paranoid thinking."
