Before Molly Murphy crossed the Atlantic or even had an inkling that she might someday become a much sought after private investigator in New York City, young Molly lived in Ireland in a small cottage with her father, brothers and little else.

While keeping herself and her home together, Molly receives a request from Lady Hartley—the lady of the country estate where Molly lives, and the family that employs Molly’s father and brothers. The Hartleys are hosting a ball at their manor house, and there will be so many fine gentlemen and ladies in attendance that Lady Hartley needs Molly to help some of her guests prepare for the ball.
