Dr. Jennifer White's best friend Amanda has been killed, and four fingers have been surgically removed from her hand. Dr. White, who suffers from dementia, is the prime suspect... and she herself doesn't even know if she's guilty. Told in White's own voice, fractured and eloquent, a picture emerges of the surprisingly intimate, complex alliance between these life-long friends, two proud, forceful women who were at times each other's most formidable adversaries. As the investigation into the murder deepens and White's relationships with her live-in caretaker and two grown children intensify, a chilling question lingers: is White's shattered memory preventing her from revealing the truth? or helping her to hide it?
