Murder in the Sun [EPUB ebook] 

Phil Nevitt, a young American, is sent by his firm to the West Indies to get information about a rival firm of distillers whose headquarters are at Annunziata, a small island seldom visited by tourists. Phil Nevitt duly arrives at the island, but in spite of its sun-drenched atmosphere of scented flowers and tinkling guitars he realises that there is something sinister about the place. Life in the sun there may be… but also Death in the sun.
