Dugasse, 68, has spent most of her life in the Seychelles and the U.K., wondering what it would be like to set foot on the tropical island of Diego Garcia, part of the remote cluster of atolls in the middle of the Indian Ocean called the Chagos Islands.

A ceremony transferring sovereignty of the British Indian Ocean Territory of the Chagos Islands to Mauritius was called off at the last moment after the High Court in London granted an injunction to islanders.
