Mary Miley grew up in New York, Pennsylvania, Illinois, and Virginia, and worked her way through the College of William and Mary in Virginia as a costumed tour guide at Colonial Williamsburg.

As Mary Miley Theobald, she has published numerous nonfiction books and articles on history, travel and business topics. As Mary Miley, she is the award-winning author of the Roaring Twenties mysteries and the new Mystic's Accomplice mysteries series. When she's not home writing, she can be found in the fields or bottling factory at Valley Road Vineyards, the Virginia winery she (and a few friends) own, where everything she does would have been illegal in the Roaring Twenties.
