Prism

"When Debra Randall goes missing, Lieutenant Patrick Garrigan, of the San Francisco police department is baffled. Because Debra is the daughter of aircraft mogul Josh Randall, the richest man in California, he assumed it was a kidnapping. Now he's not so sure. The three men in her life, her father, her best friend from childhood, Paul Diamond, and her estranged boyfriend, Blake Mallory each seem to be holding something back. Her father won't discuss her mother's death when Debra was two. Paul doesn't tell what he knows about spells that she likes to call her "feelings" that cause her to lose consciousness and time and seem to be associated with her favorite piece of jewelry, a cheap pyramid-shaped piece of glass, a prism, that she wears almost constantly. Blake doesn't tell about a threat made to Debra's life because the man who threatened seems to own law enforcement. Finding Debra, which seems pretty hopeless, may be the only way to reveal how these withheld clues are connected"--
