After her journey to France, Lady Emily Stanford resumes her much hated life as the mistress of the Greywell mansion and strives to be the obedient wife her husband, Lord Charles Stanford, wishes her to be. In the deceptive calm that follows, her brother-in-law Lyndon Stanford returns to Ireland—his former home, where he once lost his family in a brutal attack. When he unexpectedly receives details about the men involved in the deed, he sees an opportunity to get answers and perhaps even bring them to justice. His quest brings him onto unexpected paths, one of which leads to a revelation that will change his life forever, and another path once again crosses the life of his sister-in-law, Lady Emily, who is facing a personal dilemma and needs Lyndon's help.

As events unfold, old wounds begin to heal and promises of bright futures finally beckon—but then dark secrets from the past emerge, bringing with them a new enemy, who is seeking to take control over the Stanford legacy and will stop at nothing to attain it.
