Duleep Singh, the last Maharaja of the Sikh Empire, is Henry Green's great-uncle. He helps Evie find the Buckingham Palace plans in Family Politics, and is the central figure of The Last Maharaja missions, where the twins help him fight the British India Company.
Starrick's men took the palace plans before Duleep could get them for Henry. He makes Evie a deal: escort politicians he wants to win over, and he will say where copies are kept. Between rides they talk about India, her parents and Henry. After an abrasive trip with Gladstone he tells her the plans are in the White Drawing Room.
A rifle shot nearly hits him at a palace shooting contest, and the twins learn the Templars and the British India Company want him dead. Letters to his mother that the Company intercepted for years finally turn him against it. With the twins he recovers stolen Punjabi gold from a Starrick warehouse and ships it home, saving a twin from a sniper with his musket.
His next plan is to steal the Koh-i-Noor from the Tower of London. At the gala the Templars plant the diamond on him; Jacob pickpockets it before the guards search him. Henry smashes it and shows it is a fake, since his father Arbaaz made sure the real stone never left India, and the two men reconcile.
The attacks were organised by his childhood friend Brinley Ellsworth, a Templar. Ellsworth tries to kill Duleep at a meeting in Lambeth Cemetery; Evie stops him, and Duleep asks her to let him go. Duleep then tells the twins the Assassin way is not his and commits himself to India's cause.
