Sebastian St. Cyr Mystery Series

The macabre murder of a prominent nobleman throws an already unsettled London into chaos in this electrifying new historical mystery by the USA Today bestselling author of What Cannot Be Said.

August 1816. England is in the grip of what will become known as the Year Without a Summer. Facing the twin crises of a harvest-destroying volcanic winter and the economic disruption caused by the end of the Napoleonic Wars, the British monarchy finds itself haunted by the looming threat of bloody riots not seen since the earliest days of the French Revolution. Amidst the turmoil, a dead man is found hanging upside down by one leg in an abandoned chapel, his hands tied behind his back. The pose eerily echoes the image depicted on a tarot card known as Le Pendu, the Hanged Man. The victim—Lord Preston Farnsworth, the younger brother of one of the Regent’s boon companions—was a passionate crusader against what he called the forces of darkness, namely criminality, immorality, and sloth. His brutal murder shocks the Palace and panics the already troubled populace.

Sebastian St. Cyr, Viscount Devlin, learns of the murder from a ragged orphan who leads him to the corpse and then disappears. At first, everyone in the dead man’s orbit paints Lord Preston as a selfless saint. But Sebastian quickly realizes that the man had accumulated more than his fair share of enemies, including Major Hugh Chandler, a close friend of Sebastian’s who once saved his life. Sebastian also discovers that the pious Lord Preston may have been much more dangerous than those he sought to redeem.

As dark clouds press down on the city and the rains fall unceasingly, two more victims are found, one strangled and one shot, with ominous tarot cards placed on their bodies. The killer is sending a gruesome message and Sebastian is running out of time to decipher it before more lives are lost and a fraught post-war London explodes.

A seemingly idyllic summer picnic ends in a macabre murder that echoes a pair of slayings fourteen years earlier in this riveting new historical mystery from the USA Today bestselling author of Who Cries for the Lost.

July 1815: The Prince Regent’s grandiose plans to celebrate Napoléon’s recent defeat at Waterloo are thrown into turmoil when Lady McInnis and her daughter Emma are found brutally murdered in Richmond Park, their bodies posed in a chilling imitation of the stone effigies once found atop medieval tombs. Bow Street magistrate Sir Henry Lovejoy immediately turns to his friend Sebastian St. Cyr, Viscount Devlin, for help with the investigation. For as Devlin discovers, Lovejoy’s own wife and daughter were also murdered in Richmond Park, their bodies posed in the same bizarre postures. A traumatized ex-soldier was hanged for their killings. So is London now confronting a malicious copyist? Or did Lovejoy help send an innocent man to the gallows?

Aided by his wife, Hero, who knew Lady McInnis from her work with poor orphans, Devlin finds himself exploring a host of unsavory characters from a vicious chimney sweep to a smiling but decidedly lethal baby farmer. Also coming under increasing scrutiny is Sir Ivo McInnis himself, along with a wounded Waterloo veteran—who may or may not have been Laura McInnis’s lover—and a charismatic young violinist who moonlights as a fencing master and may have formed a dangerous relationship with Emma. But when Sebastian’s investigation turns toward man about town Basil Rhodes, he quickly draws the fury of the Palace, for Rhodes is well known as the Regent’s favorite illegitimate son.

Then Lady McInnis’s young niece and nephew are targeted by the killer, and two more women are discovered murdered and arranged in similar postures. With his own life increasingly in danger, Sebastian finds himself drawn inexorably toward a conclusion far darker and more horrific than anything he could have imagined.

Sebastian St. Cyr must confront a savage killer and save his closest friend from the hangman’s noose in this heart-pounding new historical mystery from the USA Today bestselling author of When Blood Lies.

June 1815. The people of London wait breathlessly for news as Napoléon and the forces united against him hurtle toward their final reckoning at Waterloo. Among them is Sebastian St. Cyr, Viscount Devlin, frustrated to find himself sidelined while recovering from a dangerous wound he recently received in Paris. When the mutilated corpse of Major Miles Sedgewick surfaces from the murky waters of the Thames, Sebastian is drawn into the murder investigation, which threatens one of his oldest and dearest friends, Irish surgeon Paul Gibson.

Gibson’s lover, Alexi Sauvage, was tricked into a bigamous marriage with the victim. But there are other women who may have wanted the cruel, faithless major dead. His mistress, his neglected wife, and their young governess whom he seduced all make for compelling suspects. Even more interesting to Sebastian is one of Sedgewick’s fellow officers, a man who shared Sedgewick’s macabre interest in both old English folklore and the occult. And then there’s the valuable list of Londoners who once spied for Napoléon that Sedgewick was said to be transporting to Charles, Lord Jarvis, the Regent’s powerful cousin, who also happens to be Sebastian’s own father-in-law.

The deeper Sebastian delves into Sedgewick’s life, the more he learns about the Major’s many secrets, and the list of people who could have wanted him dead grows even longer. Soon others connected to Sedgewick begin to die strange, brutal deaths, and more evidence emerges that links Alexi to the crimes. Certain that Gibson will be implicated alongside his lover, Sebastian finds himself in a desperate race against time to stop the killings and save his friends from the terror of the gallows.

Sebastian St. Cyr, Viscount Devlin, has spent years unraveling his family’s tragic history. But the secrets of his past will come to light in this gripping new historical mystery from the USA Today bestselling author of What the Devil Knows.

March, 1815. The Bourbon King Louis XVIII has been restored to the throne of France, Napoleon is in exile on the isle of Elba, and Sebastian St. Cyr, Viscount Devlin, and his wife, Hero, have traveled to Paris in hopes of tracing his long-lost mother, Sophie, the errant Countess of Hendon. But his search ends in tragedy when he comes upon the dying Countess in the wasteland at the tip of the Île de la Cité. Stabbed—apparently with a stiletto—and thrown from the bastions of the island’s ancient stone bridge, Sophie dies without naming her murderer.

Sophie had been living in Paris under an assumed name as the mistress of Maréchal Alexandre McClellan, the scion of a noble Scottish Jacobite family that took refuge in France after the Forty-Five Rebellion. Once one of Napoleon’s most trusted and successful generals, McClellan has now sworn allegiance to the Bourbons and is serving in the delegation negotiating on behalf of France at the Congress of Vienna. It doesn’t take Sebastian long to realize that the French authorities have no interest in involving themselves in the murder of a notorious Englishwoman at such a delicate time. And so, grieving and shattered by his mother’s death, Sebastian takes it upon himself to hunt down her killer. But what he learns will not only shock him but could upend a hard-won world peace.

Sebastian St. Cyr thought a notorious killer had been brought to justice until a shocking series of gruesome new murders stuns the city in this thrilling historical mystery from the USA Today bestselling author of Who Speaks for the Damned.

It’s October 1814. The war with France is finally over and Europe’s diplomats are convening in Vienna for a conference that will put their world back together. With peace finally at hand, London suddenly finds itself in the grip of a series of heinous murders eerily similar to the Ratcliffe Highway murders of three years before. 

In 1811, two entire families were viciously murdered in their homes. A suspect–a young seaman named John Williams–was arrested. But before he could be brought to trial, Williams hanged himself in his cell. The murders ceased, and London slowly began to breathe easier. But when the lead investigator, Sir Edwin Pym, is killed in the same brutal way three years later and others possibly connected to the original case meet violent ends, the city is paralyzed with terror once more. 

Was the wrong man arrested for the murders? Bow Street magistrate Sir Henry Lovejoy turns to his friend Sebastian St. Cyr, Viscount Devlin, for assistance. Pym’s colleagues are convinced his manner of death is a coincidence, but Sebastian has his doubts. The more he looks into the three-year-old murders, the more certain he becomes that the hapless John Williams was not the real killer. Which begs the question–who was and why are they dead set on killing again?

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.

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.
