 Eating in a dingy café, James is astounded to find a large emerald in his pocket.From reading stories in the resort's weekly paper, he has no doubt it belongs to the Rajah of Maraputna who is staying at Lord Edward Campion's private villa and that when he changed out of his bathing clothes, he put on the wrong trousers (the beach hut belonging to Lord Campion).Leaving the café he sees newspaper bills stating that the Rajah's emerald has been stolen.
