Book 15
Sebastian St. Cyr investigates the mysterious life and death of a nobleman convicted of murder in this enthralling new historical mystery from the USA Today bestselling author of Why Kill the Innocent….

     It’s June 1814, and the royal families of Austria, Russia, and the German states have gathered in London at the Prince Regent’s invitation to celebrate the defeat of Napoléon and the restoration of monarchical control throughout Europe. But the festive atmosphere is marred one warm summer evening by the brutal murder of a disgraced British nobleman long thought dead.

     Eighteen years before, Nicholas Hayes, the third son of the late Earl of Seaford, was accused of killing a beautiful young French émigré and transported to Botany Bay for life. Even before his conviction, Hayes had been disowned by his father, and few in London were surprised when they heard the ne’er-do-well had died in disgrace in New South Wales. But those reports were obviously wrong. Recently Hayes returned to London with a mysterious young boy in tow–a child who vanishes shortly after Nicholas’s body is discovered.

     Sebastian St. Cyr, Viscount Devlin, is drawn into the investigation by his valet, Jules Calhoun, an old friend of the dead man. With Calhoun’s help, Sebastian begins to piece together the shattered life of the late Earl’s ill-fated youngest son. Why did Nicholas risk his life and freedom by returning to England? And why did he bring the now-missing young boy with him? Several nervous Londoners had reason to fear that Nicholas Hayes had returned to kill them. One of them might have decided to kill him first.
 
Book 14
The death of a fiendish nobleman strikes close to home as Sebastian St. Cyr is tasked with finding the killer to save his young cousin from persecution in this riveting new historical mystery from the USA Today bestselling author of Why Kill the Innocent….

When the handsome but dissolute young gentleman Lord Ashworth is found brutally murdered, Sebastian St. Cyr, Viscount Devlin, is called in by Bow Street magistrate Sir Henry Lovejoy to help catch the killer. Just seven months before, Sebastian had suspected Ashworth of aiding one of his longtime friends and companions in the kidnapping and murder of a string of vulnerable street children. But Sebastian was never able to prove Ashworth’s complicity. Nor was he able to prevent his troubled, headstrong young niece Stephanie from entering into a disastrous marriage with the dangerous nobleman.

Stephanie has survived the difficult birth of twin sons. But Sebastian soon discovers that her marriage has quickly degenerated into a sham. Ashworth abandoned his pregnant bride at his father’s Park Street mansion and has continued living an essentially bachelor existence. And mounting evidence–ranging from a small bloody handprint to a woman’s silk stocking–suggests that Ashworth’s killer was a woman. Sebastian is tasked with unraveling the shocking nest of secrets surrounding Ashworth’s life to keep Stephanie from being punished for his death.

London, 1813. The decapitation of a wealthy plantation owner at Bloody Bridge draws Sebastian St. Cyr into a macabre and perilous investigation. The discovery near the body of a lead coffin strap bearing the inscription KING CHARLES, 1648 suggests a link between this killing and the beheading of the seventeenth-century monarch. Equally troubling, the victim’s kinship to the current Home Secretary draws the notice of Sebastian’s father-in-law, Lord Jarvis, who will exploit any means to pursue his own clandestine ends.
 
Working with his wife, Hero, Sebastian amasses a list of suspects who range from an eccentric curiosity collector to the brother of a brilliantly observant spinster named Jane Austen.
 
But as one murder follows another, it is the connection between the victims and ruthless former army officer Lord Oliphant that raises the stakes. Once, Oliphant nearly destroyed Sebastian in a horrific act of betrayal. Now he poses a threat not only to Sebastian but to everything—and everyone—Sebastian holds dear.

Described by all who knew him as an amiable young man, Ross at first seems an unlikely candidate for murder. But as Sebastian’s search takes him from the Queen’s drawing rooms in St. James’s Palace to the embassies of Russia, the United States, and the Turkish Empire, he plunges into a dangerous shadow land of diplomatic maneuvering and international intrigue, where truth is an elusive commodity and nothing is as it seems.
