The last funeral I'd been to here — also the first funeral I'd ever been to — this gear had all seemed pretty appropriate, but now I was pondering the propriety of the Docs, the 501s and the black biker's jacket. I'd hauled my white trainers out of the bag, tried one Nike on and one boot (unlaced); I'd stood in front of the tilted full-length mirror, shivering, my breath going out in clouds, while the floorboards creaked and a smell of cooking bacon and burned toast insinuated its way up from the kitchen.

The trainers, I'd decided.

So I peered down at them in the crematorium; they looked crumpled and tea-stained on the severe black granite of the chapel floor. Oh-oh; one black sock, one white. I wriggled in my seat, pulled my jeans down to cover my oddly-packaged ankles. "Hell's teeth," I whispered. "Sorry, Aunt Tone."

My Aunt Antonia — a ball of pink-rinse hair above the bulk of her black coat, like candy floss stuck upon a hearse — patted my leather jacket. "Never mind, dear," she sighed. "I doubt old Margot would have minded."

"No," I nodded. My gaze fell back to the trainers. It struck me that on the toe of the right one there was still discernible the tyre mark from Grandma Margot's wheelchair. I lifted the left trainer onto the right, and rubbed without enthusiasm at the black herring-bone pattern the oily wheel had left. I remembered the day, six months earlier, when I had pushed old Margot out of the house and through the courtyard, past the outhouses and down the drive under the trees towards the loch and the sea.
