In a city built on secrets, the deadliest betrayal comes from within.

When the body of Ryan Cooper, the Duke of Wrengate's long-lost brother, is discovered in a blood-soaked alley, Chief Constable Kendrick turns to Adrian Croft to uncover the truth. But what begins as a murder investigation soon pulls Adrian into a deadly maze of aristocratic corruption, criminal ambition, and buried secrets someone will kill to protect. As danger closes in from every side, Adrian realizes the answers may lie far closer to home than he ever imagined.

Meanwhile, Adrian's loyal valet, Murry, cannot ignore his growing feelings for Wrengate's sister, Lady Edwina, despite the impossible divide between servant and noblewoman. But with Edwina threatened by an arranged marriage meant to save her reputation, defying Society could destroy them both. And when the hunt for Ryan's killer uncovers the shadow of a far older crime, Adrian is forced to confront a truth that could shatter everything he has fought to protect.
