Dorrigo Evans and Amy Mulvaney’s affair turns a moment of acknowledged desire into a summer of secret, increasingly reckless intimacy, only to end when Keith Mulvaney reveals that he has known about it all along. The relationship’s force lies in its contradictions: the lovers seek a union that seems to abolish distance, while repeatedly encountering the other person’s separateness and the damage their desire inflicts on the life around them.

Confession and the first surrender

Amy makes her desire explicit when she tells Dorrigo that being alone with Keith makes her hate him and herself, and that she wants to be with Dorrigo. Her admission changes the terms of their closeness: what had been held back is no longer restrained, and they become physically intimate on the dunes. The scene presents desire not as a considered decision so much as a release that overtakes them. Their bodies seem to find a shared rhythm, and Dorrigo experiences the contact as a kind of improbable closeness, as if Amy had become another aspect of himself.

That apparent fusion is broken by a large dog carrying a living fairy penguin in its mouth. Dorrigo looks up from Amy and suddenly experiences her as remote, although moments earlier she had seemed inseparable from him. The animal’s violence does not explain or cause their estrangement, but its interruption marks how abruptly intimacy can change. The penguin’s shrill cry ends in a deeper howl; after the dog disappears, that sound remains with Dorrigo. The scene makes their affair’s central tension palpable from its earliest physical surrender: desire can briefly make the world seem to stop, but it cannot guarantee lasting understanding.

A summer of clandestine intimacy

As the summer continues, the affair becomes a pattern of seized opportunities. Dorrigo and Amy make love on beaches and in the ocean, in the Cabriolet, in the street behind the King of Cornwall Hotel, over a barrel of Coopers Red in the cellar, and late at night in the kitchen. The range of settings registers their willingness to risk discovery and their effort to fit desire into whatever brief interval is available. Their secrecy does not make the encounters cautious; instead, the possibility of being seen becomes part of their recklessness.

For Dorrigo, Amy’s attraction is at first difficult to believe, then tempting to dismiss as lust. Eventually he recognizes its power as something he cannot explain or resist. The narrative describes his surrender to that force without turning it into uncomplicated happiness. After lovemaking, he is often struck by Amy’s face: close to him, yet seeming to look through him. He watches her breathing and expression as if trying to assure himself that the woman beside him is real, while the feeling he names is amazement rather than joy or pride.

One morning, when Keith has gone to town for a meeting, Amy visits Dorrigo’s room. Their conversation gives way to an embrace, a kiss, and sex. As Dorrigo looks down at her, Amy seems absent from the encounter, absorbed in an experience that belongs to her alone. Her unfocused gaze and shallow breathing unsettle him. He wonders whether she is seeking obliteration through him, as though he were a passage to somewhere beyond the world. The encounter reverses the earlier fantasy of mutual fusion: Dorrigo recognizes that her intensity does not mean he understands her, and that the mystery is not hers alone.

The affair within Amy’s marriage

The affair takes place alongside a marriage that remains outwardly comfortable. Amy thinks of the Edwardian horsehair furniture Keith refused to replace: it sags, and comfort is possible if one settles into its soft places and avoids the hard ones. Keith is unselfish and kind, but Amy measures that goodness against her desire for Dorrigo and finds that it cannot make her feel she is in love. She returns to Keith’s bed amicably and quietly, while concealing an inner life in turmoil.

Amy’s guilt is not simply a wish to be forgiven. During the day she can live with it; at night it presses on her until she has to slow her breathing. What she longs for is the reconciliation of her truth with the life she is living, followed by the possibility of leaving. That wish sharpens the cost of the affair: the secret does not resolve the contradiction between her marriage and her desire, but makes her daily return to Keith more difficult to sustain. Her private conflict exists alongside Dorrigo’s consuming attachment, without becoming identical to it.

Discovery and rupture

The summer ends when Keith tells Amy that he knows about the affair and has always known. His disclosure overturns the lovers’ assumption that what they have hidden has escaped him. Amy wonders how he could have known when she and Dorrigo had not realized he did; Keith’s guileless relationship with truth makes her doubt that he is bluffing. He has carried his knowledge silently and patiently until, on the drive back from the Robertsons’, he can no longer bear it.

The discovery does not arrive as a gradual unravelling of the affair but as a sudden break after a season in which desire has seemed inexhaustible. The narrative compares the ending to a joyriders’ car smash, setting the affair’s headlong momentum against the abrupt violence of its collapse. Keith’s knowledge also changes the meaning of the marriage Amy had treated as a separate, if increasingly intolerable, world: he has not been unaware of the truth she has hidden there.

Narrative significance

The affair is defined by a persistent mismatch between bodily intensity and emotional certainty. Amy and Dorrigo repeatedly seek one another with an urgency that seems to overcome restraint, yet the first encounter already turns from closeness to distance, and later Dorrigo sees that Amy may be reaching for an oblivion he cannot share or interpret. The relationship’s physical abundance therefore does not settle the question of what they mean to each other.

Its ending also refuses to make secrecy equivalent to privacy. Amy and Dorrigo take their chances in multiple places, but Keith has been silently carrying knowledge through the same summer. The affair’s final reversal brings the hidden marriage back into view and breaks the lovers’ self-contained world. What remains is not a simple triumph of passion or a clean moral resolution, but the exposure of how desire, concealment, guilt, and unspoken knowledge have occupied the same season.
