A chilling disappearance, a lethal enemy, and a family pushed to the brink...

When the Duke of Wrengate's sister vanishes without a trace, suspicion swirls. Did she flee to escape a scandalous secret, or has she been abducted?

Determined to uncover the truth, Adrian Croft and his valet, Murry, plunge into London's darkest corners.

But while Adrian is drawn deeper into the search, Finn O'Leary is preparing his final move. With Samantha fighting for her life after the birth of their daughter, Adrian's family is more vulnerable than ever. And when Finn strikes, Adrian must risk everything to protect the people he loves and finally put an end to the enemy who has haunted him for too long.
