" Outside, a dog sprawls among the empty tables, its body rocking with the evening heat. Someone has given it a hamburger which first it guards, then, eventually, eats. It's some kind of winter dog, a malamute perhaps, a dog of marvellous subtle greys and whites. Also of transparent intelligence, and less transparent motive. The beauty of an animal like this appears to fix it in our expectations. But while its beauty says one thing, its heart may say another. "
