1812 – Recovering in Naples from the intrigues of Scottish politics, Charles Murray is drawn further afield by urgent news of an old servant in distant Mughal India. Going to the aid of one woman, he finds another and is pursued by a third. But that is no recipe for an easy life, and with imperial spies on the streets of Delhi, Murray must investigate the murder that brought him to the East, and redeem himself in his own eyes. The Tender Herb is the sixth in the Murray of Letho series.
