That day the four of them went to the library, though at different times. The library assistant, if he had noticed them at all, would have seen them as people who belonged together in some way. They each in turn noticed him; with his shoulder-length golden hair. Their disparaging comments on its length, its luxuriance, its general unsuitability – given the job and the circumstances – were no doubt reflections on the shortcomings of their own hair. Edwin wore his, which was thin, greying and bald on top, in a sort of bob – ‘even older gentlemen are wearing it longer now’, his barber had told him – and the style was an easy one which Edwin considered not unbecoming to a man in his early sixties. Norman, on the other hand, had always had ‘difficult’ hair, coarse, bristly and now iron-grey, which in his younger days had refused to lie down flat at the crown and round the parting. Now he did not have to part it and had adopted a medieval or pudding-basin style, rather like the American crew-cut of the forties and fifties. The two women – Letty and Marcia – had hair as different from each other as it was possible to imagine in the nineteen seventies, when most women in their sixties had a regular appointment at the hairdresser for the arrangement of their short white, grey or dyed red curls. Letty had faded light brown hair, worn rather too long and in quality as soft and wispy as Edwin’s was. People sometimes said – though less often now – how lucky she was not to have gone grey, but Letty knew that there were white hairs interspersed with the brown and that most people would have had a brightening ‘rinse’ anyway. Marcia’s short, stiff, lifeless hair was uncompromisingly dyed a harsh dark brown from a bottle in the bathroom cupboard, which she had used ever since she had noticed the first white hairs some thirty years earlier. If there were now softer and more becoming ways of colouring one’s hair, Marcia was unaware of them.
