Dr Thomas Silkstone Mysteries #6
Past misdeeds come back to haunt the residents of Boughton Hall with a vengeance as first Sir Montagu Malthus is found brutally slain, then the grave of Lady Lydia Farrell’s dead husband is desecrated and the diamond ring he was wearing when buried is stolen.
Using his newly-honed forensic skills Dr Thomas Silkstone discovers the crimes are linked to India where the late Captain Farrell served in the army. The arrival in London of Dr Carruthers’s brother, an expert in the ancient language of Sanskrit, throws new light on the investigation.
A visit by the Governor-General of India’s wife, a society beauty renowned for her love of gems, means that Thomas fears for her life. More bizarre murders lead the young anatomist to discover the existence of an ancient map of the diamond mines of Golconda. Dead men’s diamonds, it seems, hold the key to untold riches and the race is on to find where Lydia’s late husband has hidden the map before she, too, falls prey to the demented murderer who’s on the loose.
