“There’s an old joke about a man who buys a cookbook for his wife and a negligee for his mistress. Somehow, though, the two parcels get mixed up and he fears that all will be lost. But on the contrary both women are delighted: the wife thrilled to be viewed in a sexual manner after years of domestic tedium, the mistress overjoyed that her lover considers her as more than just a body. I imagined the scenario as I trudged my way through Myer and David Jones. Should I look for lingerie for Cress, reassure her that despite all the hiccups of the past few months I still loved and wanted her? I thought I did, but a leopard-print G-string didn’t seem the right way to express that.”

“Chemistry is an overused word. I prefer ‘fit’, that indefinable sensation when a man takes your arm as you move through a door, or leans into you to light your cigarette. (I gave up smoking for Cary and sometimes I still miss it.) Fit is an understanding between bodies: that you’ve been designed the same way, that you speak each other’s language, and fluently. It’s all about physical compatibility and has nothing to do with whether you’ll last or even have anything to talk about afterwards; fit is no relation to the brain, and only a distant cousin of the heart.”

“I’m not proud of any of this, truly I’m not. Looking back I can’t believe how I acted, how each deceit flowed so seamlessly from another. My only excuse is that I was addicted, and like any addict all I could think about was my next hit. Hurting Cary didn’t seem of any consequence, neglecting Sarah or my work was unimportant. All that mattered was Luke and the singing in my veins whenever we were together.”

“Tired, yes, but it was more than that. Watching everything unfold had lurched me from anger to disgust and finally sorrow, had reminded me that love is fleeting and precious and should never be taken for granted. All of a sudden I felt the need to seize it with both hands, to assure myself that the same pain wouldn’t be mine.”

“Oh, I already loved my husband, of course, but this was different. That had been a decision; this was out of my control, an impulse as difficult to resist as gravity. Mad love, crazy love, drop, sink, stumble. The kind of love where every little thing is a sign, a portent: the song on the radio, his Christian name staring up at you from a magazine you’re flicking through, your horoscope in the paper. Normally I don’t even believe in horoscopes, for God’s sake. Love without holes or patches or compromises, soft as an easy chair, a many splendoured thing.”

“I was out of control, manic, less myself than I’d ever been. Like Eve must have felt after the fall, I reflected as I drove away. Leaving Eden for a land unknown.”

“I literally felt gutted, as if someone had hollowed me out, removed my core. Patients in the final stage of dementia revert to an almost neonatal state, their brains so atrophied they can only breathe and digest, suck and pout. That was how I felt. I continued to function, but only at the most basic level, my existence little more than a collection of primitive reflexes.”
