Strangely, our sexual acts took place only within my automobile. In the large bedroom of her rented house I was unable even to mount an erection, and Helen herself would become argumentative and remote, talking endlessly about the more boring aspects of her work. Once together in my car, with the crowded traffic lanes through which we had moved forming an unseen and unseeing audience, we were able to arouse each other. Each time she revealed a growing tenderness towards myself and my body, even trying to allay my concern for her. In each sexual act together we recapitulated her husband's death, re-seeding the image of his body in her vagina in terms of the hundred perspectives of our mouths and thighs, nipples and tongues within the metal and vinyl compartment of the car.

I waited for Catherine to discover my frequent meetings with this lonely woman doctor, but to my surprise she showed only a cursory interest in Helen Remington. Catherine had rededicated herself to her marriage. Before my accident our sexual relationship was almost totally abstracted, maintained by a series of imaginary games and perversities. When she stepped out of bed in the mornings she seemed like some efficient mechanic servicing herself: a perfunctory shower; the night's urine discharged into the lavatory pan; her cap extracted, re-greased and once again inserted (how and where did she make love during her lunch-hour, and with which of the pilots and airline executives?); the news programme played while she percolated the coffee…

All this had now passed, replaced by a small but growing repertory of tendernesses and affections. As she lay beside me, willingly late for her office, I could bring myself to orgasm simply by thinking of the car in which Dr Helen Remington and I performed our sexual acts.
