In the third installment of the Le Fanu Mystery series, the intrepid superintendent is promoted to Inspector-General of Police in 1920s Madras, which proves to be more boring than he had envisaged. Instead of pushing papers across his desk, Le Fanu focuses on the disappearance of a senior Indian Civil Service officer and an apparently unrelated murder. As the two incidents intertwine, the world-weary detective is drawn into the worlds of indentured labour recruitment and antiquities theft.
