In 1925 beautiful, bohemian Diana Pollexfen was celebrating her 30th
birthday with a party at a country estate, but the celebrations soured
when her husband died, poisoned by a cocktail that had been liberally
laced with some of Diana's photographic chemicals. Sixty years later,
Diana's grand-niece, Helena, is also turning 30, but with rather less
fanfare. An overworked attorney in London, Helena's primary social
outlet is an obsessive love affair. By way of distraction, Helena starts
looking through her great-aunt's papers and soon develops another
obsession: Determining just who did kill George Pollexfen in that
lovely, sunlit garden between the wars.
