The Best Laid Plans
(1952)(Book 13 in the Chief Inspector William Austen series)
A novel by Anne Hocking
From the Book Jacket: "Warren was really sorry he had to murder his wife: she was easy to live with, and in a way he was quite fond of her. If it had been only a question of money, he wouldn't have thought of it. But now there was Julia. Warren was a thwarted novelist. Warren was also in love with Julia, a woman who had achieved distinctions as a writer, a woman who moved through select literary circles and could easily take him with her...."
