The Maharaja's beautiful and resourceful mistress Sirene is a sexually liberated woman who is no stranger to Simla. The former governess' glittering ascent stuns the snobbish local British wives, but Sirene is mindful that this high life won't last forever.

As Ralph goes to work on the Maharajah, his wife Madeleine does all she can to cultivate Sirene. But this exotic couple have other plans for the young Englishman.

Sirene is played by Rachel Griffiths.
