Palette of Secrets is a mystery story about a famous artist, Nancy Miller.  Nancy is growing old and is in the early stages of Alzheimer& 39;s. She has been persuaded by her agent to publish her memoirs but needs a ghost writer to help her to write them.  She finds a young woman called Ana who is keen to take on the job.  However, as Nancy starts to recount her life story, it becomes obvious to Ana that the artist is hiding something, so she decides to dig more deeply to unravel Nancy’s past.  However, when she eventually works out what Nancy& 39;s terrible secret is, she doesn& 39;t know what to do with the information; should she include it in the book and risk ruining Nancy& 39;s international reputation or should she tell Nancy& 39;s son what she has discovered?  Either way the consequences threaten to be devastating for Nancy and her family.
