Monkshood

Aileen Seaton, a lawyer and former fencing champion, hears a dying man's confession: he swears the best-selling Scottish writer Calum Weir is innocent of the double murder of his wife and her lover. When Aileen meets Weir in prison, she realizes that he remembers nothing of the horrific murders. But why is he even scared to talk about them? And why do his terrifying nightmares involving the poisonous plant, monkshood? Together they reconstruct the murder scenario, and after interrogating the writer's previous lovers, friends, and rivals, Aileen feels sure someone plotted to incriminate Weir and put him away for life. As she pierces together the enigma the killers emerge, and only Aileen's talent with an old dueling sword can save her.
