The 18th-century meets the sharp blade of forensic science... 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... The Dr Thomas Silkstone Mysteries are perfect for fans of Antonia Hodgson's The Devil in the Marshalsea, E. S. Thomson's Jem Flockhart series and Sarah Perry's The Essex Serpent.
