Theo gets engaged to Kitsey

Theo Decker and Kitsey Barbour become engaged in a moment of shared exhilaration on Park Avenue, a decision driven by a desire to move forward, please Kitsey's mother, and escape the painful obsession Theo feels for Pippa Blackwell. The engagement, however, is built on a fragile foundation of mutual convenience and unspoken secrets, and it quickly becomes strained by Theo's deepening depression, his unresolved feelings for Pippa, and Kitsey's ongoing affair with Tom Cable.

The Proposal and Initial Joy

The proposal itself was spontaneous and electric. On their way to a party, both a little drunk, Kitsey and Theo stepped out onto Park Avenue. The street lights snapped on the moment they did, a coincidence so perfect it struck them both as hilarious. In that moment of shared laughter and light, Kitsey seized Theo's hand and said, "You know what I think we should do, Theo?" He knew exactly what she was going to say. When he asked, "Should we?" she replied, "Yes, please! Don't you think? I think it would make Mum so happy." The decision was made in a flash, fueled by the belief that it was the right thing for everyone. Theo was swept up in a giddy, delirious energy that summer, running on gin and the invigorating thrill of it all, thinking only of Kitsey. The memory of telling Mrs. Barbour, of seeing her startled eyes bloom with delight, was a moment he played over and over, never tiring of it. He felt a clean pain, a stark contrast to the dull misery of his years under the influence of drugs, as if he had removed a pair of smudged glasses.

A Growing Unease and the Shadow of the Past

Despite the initial euphoria, the engagement soon began to feel like a trap. By the time they were registering for china at Tiffany's, Theo was overwhelmed by a sense of dread. The pristine, gleaming displays of new tableware, with their tacit promise of a shiny, tragedy-free future, struck him as profoundly sad, reminding him of the funeral sales and broken-up households he knew from his work. He felt a suffocating sadness that stretched in every direction, and the social pace of the wedding preparations—the dinner parties, the busy restaurant tables with Kitsey's friends—became an immense strain. He was jumpy, un-opiated, and wracked to the last synapse, finding it hard to make the proper show of social ardor. He began to notice a troubling lack of depth in Kitsey. She was never tired, never unhappy, but nothing ever seemed to strike her as particularly urgent or emotional. He kept watching for some evidence of sorrow about her father and brother, Andy, and it was starting to disturb him that he hadn't seen it. Her sparkling blue shallows, so enticing at first, had not yet graded off into depths, leaving him with the disconcerting sensation of wading in knee-high waters, hoping for a place deep enough to swim.

The Fracture: Kitsey's Betrayal

The fragile peace of the engagement was shattered when Theo discovered Kitsey's ongoing affair with Tom Cable. After a tense encounter with Kitsey's roommate, who refused to let him into the apartment, Theo saw them on the street: Kitsey, head down in her pink Prada overcoat, huddled arm in arm and whispering with Cable, who kissed her with a mournful tenderness Theo had never seen from her. The revelation was a brutal shock, but it also brought a strange clarity. When confronted, Kitsey admitted the affair but argued that their marriage was still the right thing for both of them. She pointed out that Theo was a drug addict and that they were a good match, that they made each other better people. She told him, with plain pity and affection, "Let's both be good, and truthful, and kind to each other, and let's be happy together and have fun always." Theo, recognizing the truth of her words about his own failings and his own hopeless love for Pippa, felt his anger drop away. He spent the night with her, but the unbridgeable distance between them left him feeling completely alone.

The Engagement Party and a Final Escape

The engagement party at Anne de Larmessin's private club was a grand affair, but for Theo it was a nightmare of social performance. He was trapped in conversation with strangers, including the sinister Havistock Irving, who was connected to Lucius Reeve and knew about the fraudulent furniture sales. The party was a blur of forced smiles and clinking glasses, a stage set for a life he was no longer sure he wanted. The only bright spots were brief, painful encounters with Pippa and a surprise visit from Boris, who had come to the party. Boris, seeing Theo's distress, pulled him aside and told him they needed to leave immediately for Amsterdam to recover the painting. The prospect of escape was overwhelming. Theo agreed without hesitation, telling Kitsey he was leaving on business. He walked out of the party, leaving behind the champagne and the congratulations, and stepped into a waiting car with Boris, heading for the airport and a confrontation with his past.
