The island next to Johnny Depp's Caribbean retreat is on the market. Halls Pond Cay, which is part of the exclusive Exumas Island chain, is on sale for $62 million (£41.3 million). Depp whisked his new bride Amber Heard and 50 other guests off to his private island, Little Halls Pond Cay, on 8 January (15) to celebrate his wedding. He purchased the 45-acre island 11 years ago.
