To all appearances, Miss Omega Chartley is a school-teacher on holiday. In fact she is a gentlewoman fallen on hard times, left at the altar eight years earlier and forced to make her own way in the world after the loss of her family fortune.

Omega’s modest tour of England is cut short when she comes to the aid of a runaway. Jamie Clevenden has fled the clutches of a brutal uncle, and Omega is determined to help him escape the law, as represented by Bow Street Runner, Mr. Timothy Platter.

Aided by a kindly war veteran and his adopted daughter, the two fugitives arrive at the home of Jamie’s other uncle, the Viscount of Byford—none other than Miss Chartley’s disgraced fiancé, Matthew Bering. There Miss Chartley will finally learn the secret that Lord Byford has hidden from her all these years, the story of the dark chapter in his past that stands in the way of not only their happiness but that of his nephew. Now they must face the truth together, no matter how dire the consequences.
