Evil Under the Sun, Agatha Christie

The perfect holiday… For a passionate crime It was not unusual to find the sun-loving Arlena Stuart stretched out on a beach, face down. Only, on this occasion, there was no sun…she had been strangled. Ever since her arrival, the air had been thick with sexual tension. Each of the seaside guest had a motive to kill her, including Arelena’s new husband. But Hercule Poirot suspects that this apparent ‘crime of passion’ conceals something much more evil.
