The Fire in the Flint — Candace M. Robb

“Intrigue abounds” in the series starring sleuth Margaret Kerr. “Robb's captivating blend of history and mystery vividly evokes medieval Scotland” (Booklist).
 
Scots are gathering in Murdoch Kerr's Edinburgh tavern, plotting to drive out the English forces. Margaret takes her place there as innkeeper, collecting information to pass on to William Wallace -- until murder gives the English an excuse to shutter the tavern. The dead man was a witness to the intruders who raided chests belonging to Margaret's husband and her father, the latest in a string of violent raids on Margaret's family, but no one knows the identity of the raiders or what they're searching for.
 
Margaret's uncle urges her to escape to Edinburgh, but as she flees north with her husband Roger, Margaret grows suspicious about his sudden wish to speak with her mother, Christiana, who is a soothsayer. Margaret once innocently shared with Roger one of Christiana's visions, of “the true king of Scotland” riding into Edinburgh. Now she begins to wonder if their trip is part of a mission engineered by the English crown . . .
