The year is 1942. World War II is in full swing in the Atlantic. The Caribbean islands form an arc of lookout posts arrayed against an unseen enemy. From here Great Britain and the United States spy the waves for German U-boats attempting stealthy approaches to the Panama Canal, the Gulf of Mexico and the strategic ports of South and Central America. Far from the deadly fray out in the mid Atlantic, life could have gone on as usual in the British colony of Trinidad. But this cosmopolitan island has become a crucial outpost, now manned by thousands of American servicemen. And as the days grow hotter and the nights grow longer lying in wait for those Nazi ships, restlessness turns to mischief, and mischief turns to murder.
