Mask of Sanity

For the last year Tricia Gleason shifted back and forth from fishing guide on Tillamook Bay to homicide detective. In the latter role she "fished" for clues to solve two murders.
To celebrate the new day Tricia makes the decision to leave her fishing and detective roles. And, to the voice of her heart, sets the goal to become a minister. Puts her detective hat and her fishing waders in the closet. Closes the door.
Hope? To attend classes at Ocean Divinity School in Berkeley, California and learn about the Bible. Hope? To be a good seminary Field Work student at a Palo Alto Community Congregational Church. Hope? To be effective in leading a college church group of Stanford students.
But then. Her first night a troubled Stanford student wants to share personal problems. Tricia glances at her watch, the student reads her dismissing body language and leaves. Tricia doesn't see her again...until she is in the morgue. When the casket closes on this coed Tricia's closet door opens. At first she doesn't know the murderer is in her midst, closer than bad breath. On goes the detective hat.
Tricia learns she is dealing with more than two women, only distinguished by reddish-orange hair and neon-blue hair. Tricia surmises there is a third person, a primary identity. And then she knew: the murderer actually is someone whose public persona is rational and impressive. This person wears a mask of sanity, hiding the blue and red haired impersonations. As Tricia moves in there is only one problem...she has the wrong sane person in her sights.
Would the mask of sanity ever be ripped off?
