Another enjoyable Barbara Vine , pseudonym for Ruth rendell (winner of the Mystery Writers of America Grand Master Award for lifetime achievement) book. I only recently found out this was a nom de plume. I'm working my way reading & listening through all her work, that I can ...worth it.
When succesful author Gerald Candless dies of a sudden heart attack, his eldest, adoring daughter Sarah embarks on a memoir of him and soon discovers that her perfect father was not all he appeared to be. That infact he wasn't Gerald Candless at all. But then, who was he? And what terrible secret had driven him to live a lie for all those years?
