Plot summary

Married for 45 years, without children, Kate and Geoff Mercer are poised to celebrate their wedding anniversary with a party, when Geoff receives a letter that shakes both of them. The letter, from Switzerland, lets him know that a body has been found: that of Katya, his girlfriend before Kate, who died falling into a fissure in a glacier when the couple were on a walking holiday in 1962. Geoff tells Kate that he was regarded as Katya's next-of-kin, since they had been pretending to be married. Though Kate continues to prepare for the party, and the couple shares some romantic excitement about it, she becomes increasingly disturbed by Geoff's preoccupation with Katya. Geoff begins smoking again; reminisces at length about his carefree time with his previous love; seeks out photographs of her in the attic; and complains bitterly about the way his contemporaries and ex-colleagues have aged. Under Kate's questioning, he states that he would have married Katya had she lived. While Geoff is at a work lunch, Kate searches the attic and finds slides of Katya, which reveal that she was pregnant at the time of her death. As the celebrations grow closer, they delve further into their past, leaving their future in question.—yusufpiskin
