Captain Jim Agnihotri and Lady Diana Framji return to India as they investigate a murder amidst colonial Bombay's complex hierarchy in March's fourth mystery.

In 1894 colonial India, Lady Diana's family has lost their fortune in a global financial slump, but even worse, her brother Adi is accused of murder. Desperate to save him from the gallows, Captain Jim and Lady Diana rush back to Bombay. However, the traditional Parsi community finds Jim and Diana's marriage taboo and shuns them.

The dying words of Adi’s business partner, a silversmith, are perplexing. As Captain Jim peels back the curtains on this man's life he finds a trail of unpaid bills, broken promises, lies and secrets. Why was the silversmith so frantic for gold, and where is it? What awful truth does it represent?

Set in lush, late-Victorian India, Captain Jim and Diana struggle with the complexities of caste, tradition, and loyalty. Their success and their own lives may depend on Diana, who sacrificed her inheritance for love. Someone within their circle has the key to this puzzle. Can she find a way to reconnect with the tight community that threw them aside?
