Secrets in the stones

the long version

1775. 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.
