"I imagine you were planning to."

Malloy cleared his throat. "That's one way to look at them."

"Don't be servilely civil to me. That is an accurate, clinical description of the Riders—they are a cerebral infection."

"You mean their powers of emergency telepathy and precognition, their seeming secondary personality—all that's a hallucination?"
