Messenger of Truth
by Jacqueline Winspear
This is the fourth book in the Maisie Dobbs series. I have loved all of the books so far. The characters are interesting and well-developed, the stories are fascinating (and you learn a bit of history along the way) and compelling, and the writing is excellent. AND, they are clean. Bonus!
Maisie is a great heroine, and I love the character development that continues throughout the series. She grows as a person, as well as in her profession. Highly recommended! You must start with "Maisie Dobbs: A Novel."
