Evil Under the Sun

Hercule Poirot arrives at a beautiful vacation island in the Adriatic Sea, expecting a relaxing holiday. Unbeknownst to him, dark secrets lurk beneath the island's picturesque facade.

The tranquility of the island is shattered when former actress Arlena Marshall is discovered strangled on the beach. The local authorities are called, and the guests are thrown into a state of shock.

As the detective, Hercule Poirot offers his services to investigate the murder. Each guest at the resort becomes a suspect, with Poirot quickly realizing that everyone had a potential motive.

Poirot interviews the guests, uncovering layers of secrets and resentments. The complexity of human emotions becomes evident, as most guests claim to have alibis at the time of the murder.

During his investigation, Poirot learns about the affair between Arlena and Patrick Redfern. The relationship had become a source of conflict, affecting not only Patrick's marriage but also other guests.

Investigation reveals that a valuable diamond, previously in Patrick’s possession, had been stolen. The diamond becomes a crucial focus for Poirot, hinting at deeper motives behind the murder.

Poirot discovers that Patrick's wife was not only aware of the affair but had a hand in the ruse to misdirect the investigation. Her seemingly supportive demeanor raises suspicions about her involvement.

In an elaborate trick, Patrick's wife impersonates Arlena after her murder to throw Poirot off the scent. The cunning plan reveals the lengths to which they would go to protect themselves.

Poirot connects the dots between Arlena's murder and a previous unresolved case involving a vagrant. This discovery opens up new avenues for investigation and reveals a pattern of deceit.

Confronted by Poirot, Patrick attempts to defend his actions regarding the affair and the murder. His alibi begins to crumble as Poirot lays out the evidence against him.

In a dramatic unveiling, Poirot reveals the truth behind Arlena's murder, exposing Patrick and his wife's conspiracy. The motives tied to jealousy and greed come to light, shocking the other guests.

As the authorities take Patrick and his wife into custody, the other resort guests find closure. Poirot reflects on the nature of evil, recognizing that it can exist even in paradise.

With the case resolved, Poirot prepares to leave the island, contemplating the darker side of human nature. He departs, leaving behind the chaos and treachery that once plagued the idyllic location.
