EVA

Tyvian Jones, a Welsh author from a working-class coal mining background, comes to Venice, rich and famous from the success of his first novel and its film adaptation by the Italian director Sergio Branco Mallone. Sergio and Tyvian compete for the affections of Sergio's assistant Francesca, who falls in love with Tyvian and gets engaged to him, but wants to keep her job with Sergio. Tyvian resents Sergio's demands on Francesca's time, but still accepts an advance from Sergio to begin writing a new novel, which Sergio hopes to film.

Francesca leaves on a business trip to Rome with Sergio, and Tyvian returns to his Venice house to find it occupied by local businessman Pieri and his "friend", a French call girl named Eve "Eva" Olivier. The couple broke in to take shelter after their boat's rudder failed in a storm. Initially angry, Tyvian finds himself strongly attracted to Eve and, after throwing Pieri out of the house, tries unsuccessfully to seduce her. Eve knocks him unconscious and leaves.

Tyvian tracks Eve to her penthouse apartment in Rome, where she has many clients. After pursuing her for several days, he finally succeeds in having sex with her. She indicates her primary interest is money, and warns him not to fall in love with her. His friends see him out with Eve, causing an upset Francesca to confront him and Sergio to berate and threaten him. Despite this negative fallout, Tyvian cannot resist spending an expensive weekend in Venice with Eve, where he reveals to her that his best-selling book was actually written by his deceased brother. Tyvian has begun to drink heavily and ends up publicly humiliated and rejected by Eve, who used the weekend to make money gambling and connecting with wealthy new clients.

Tyvian marries Francesca. Meanwhile, Sergio has discovered that Tyvian lied about his past and did not write the book published under his name, but cannot get Francesca to leave Tyvian. While Francesca is away working with Sergio, Tyvian trysts with Eve in his home. Francesca unexpectedly returns, discovers Tyvian with Eve, and, distraught, rushes away in a motorboat and dies in a crash. The night of her funeral, Tyvian breaks into Eve's apartment seeking comfort, but Eve drives him out with a riding whip and pushes him into a garbage pile.

Two years later, Sergio still mourns Francesca, while Tyvian haunts the bars of Venice and pursues a contemptuous Eve, who is planning to sail to the Greek islands with a wealthy Greek client.

Tyvian’s obsession leads to Francesca’s accidental death and his own downfall, as Eva ultimately rejects him, leaving him alone and disgraced years later.

The ending cements Eva as an untouchable force and Tyvian as her casualty; his fixation costs him love, reputation, and purpose. Francesca's tragic death underscores the collateral damage of Tyvian's self-destruction. Losey’s conclusion is a study in the perils of obsession and the soulless pursuit of desire, with Eva remaining indifferent while Tyvian is left to haunt the shadows of Venice.
