Arlena Stuart, the famous actress, is enjoying—like our favorite Belgian detective Hercule Poirot—a summer holiday on Smugglers' Island, and will become a common enough sight, sunbathing on the hot sands. Then one azure morning her beautiful bronzed body is discovered in an isolated cove, in the shade. She is dead, strangled. And Poirot, as luckless as ever when he attempts some down-time, will learn in the course of his investigation that nearly all the guests of this exclusive resort have some connection to Arlena. But who had the capacity and the motive to kill her?
