Newly released from the notorious asylum known as Bedlam, Lady Lydia Farrell finds herself in an equally terrifying position—as a murder suspect—when she stumbles upon the mutilated body of Sir Montagu Malthus in his study at Boughton Hall.

Meanwhile Dr. Thomas Silkstone has been injured in a duel with a man who may or may not have committed the grisly deed of which Lydia is accused. Despite his injury, Thomas hopes to clear his beloved’s good name by conducting a postmortem on the victim. With a bit of detective work, he learns that Montagu’s throat was slit by no ordinary blade, but a ceremonial Sikh dagger from India—a clue that may be connected to the fabled lost mines of Golconda.

From the mysterious disappearance of a cursed diamond buried with Lydia’s dead husband, to the undying legend of a hidden treasure map, Thomas must follow a trail of foreign dignitaries, royal agents—and even more victims—to unveil the sinister and shocking secrets in the stones…
Praise for The Devil’s Breath

“Excellent…Both literally and figuratively atmospheric, this will appeal to fans of Imogen Robertson’s series during the same period.”
