Hallucinations, I thought bitterly. Never dreams.

"Have they intensified? Become more personal? Are you afraid?"

"Andrew Fielding is dead," I said in a flat voice.

Rachel blinked. "Who's Andrew Fielding?"

"He was a physicist."

Her eyes widened. "Andrew Fielding the physicist is dead?"

It was a measure of Fielding's reputation that a medical doctor who knew little about quantum physics would know his name. But it didn't surprise me. There are six-year-olds who'd heard of "the White Rabbit." The man who had largely unraveled the enigma of the dark matter in the universe stood second only to his friend Stephen Hawking in the astrophysical firmament.

"He died of a stroke," I said. "Or so they say."

"So who says?"

"People at work."

"You work with Andrew Fielding?"

"I did. For the past two years."

Rachel shook her head in amazement. "You don't think he died of a stroke?"

"No."

"Did you examine him?"

"A cursory exam. He collapsed in his office. Another doctor got to him before he died. That doctor said Fielding exhibited left-side paralysis and had a blown left pupil, but…"

"What?"

"I don't believe him. Fielding died too quickly for a stroke. Within four or five minutes."

Rachel pursed her lips. "That happens sometimes. Especially with a severe hemorrhage."

"Yes, but it's comparatively rare, and you don't usu¬ally see a blown pupil." That was true enough, but it wasn't what I was thinking. I was thinking that Rachel was a psychiatrist, and as good as she was, she hadn't spent sixteen years practicing internal medicine, as I had. You got a feeling about certain cases, certain peo¬ple. A sixth sense. Fielding had not been my patient, but he'd told me a lot about his health in two years, and a massive hemorrhage didn't feel right to me. "Look, I don't know where his body is, and I don't think there's going to be an autopsy, so-"
